About this book

Who this book is for

Maybe you are new to digital recording. Maybe you are curious about Linux. Maybe you have been using a Digital Audio Workstation, but are interested in getting away from the Microsoft/Apple duopoly or just want to try a new DAW. Maybe you have already been using Ubuntu Studio, but would like to explore more of it's features or could use a trusty handbook as a quick reference. This guide to home digital recording and music production with Ubuntu Studio is for the amateur or semi-professional (professionals welcome, too!) musician.

No knowledge of Ubuntu is required - this book in not an Ubuntu manual, but will cover the basics of the operating system needed to use the music software, including installation and command line operations. If you have used a PC or Mac, you already know just about everything you need to know and will be in very familiar territory.

Why use this book?

• For a complete overview of native and many non-native instrument and effect plugins, multitrack recording software, touching on synthesizer programming and review how to share your recordings online while stating your intentions for use via Creative Commons.
• Learn advanced techniques like synthesizer programming, creating soundfonts, turning your guitar into a MIDI controller, track automation, basic mastering, and more.
• Save time - no need to wade through online forums or watch slow-paced YouTube video tutorials – go straight to the information you need.
• Save money – Ubuntu Studio and all of the bundled software are free. And Ubuntu is closely tied to the kernel, meaning it runs very fast, even on older computers. If you have an old PC that could not take the Windows 10 upgrade, it could have a second life as a music workstation We cover this in detail in the next chapter.
• Compliment other resources The online forums, assorted manuals, and YouTube videos are great, especially on narrow topics. Many links to these resources are provided throughout the this handbook. While there are many books about Ubuntu, they do not cover the music software, I was never able to find a book on the Ubuntu Studio distribution. My hope is that, like me, you just want to see how things work and get on with making music.

How to use this book

You might be stuck on something. This book may or may not provide the answer, but it will show that, with a little patience, you can get un-stuck from whatever the problem is. I tried everything as I wrote – demonstrating that “it really does do that”. Maybe there's a buried menu, hard-to-find checkbox, or something needs to be restarted/re-installed. The point is: knowing what's possible is valuable in itself because it shows persistence will be rewarded.

• There is no need to read this book cover-to-cover. It's fine to skip over things you know to the things you want to learn about.
• Have a book marker at hand so you can try things out as you go. Do put the book to one side and open a new project or noodle around with presets whenever the mood strikes.
• Callouts like the one to the right contain helpful tips.
• Your feedback is welcome at the book web site, where you can also find a few free downloads.

Advanced Recording in Ardour

I hope that you have taken time out from reading this book to experiment with some of the synthesizer plugins and to make at least one short recording, not because it's necessary to move on, but for fun. Now we'll review some additional features and techniques of recording in Ardour.

Punch-ins

If you have a near-perfect take with one or two glitches, it's possible to set the track to record only a glitch region. Using the Range tool, highlight the part of the track where the glitch is. Then right-click-hold that highlighted area, and choose "Set Punch from Range" in the middle of the dropdown menu that will appear. Two Loop/Punch Range markers will appear in the marker area. Zoom in to make any fine adjustments to where the recording will start and stop. Arm the track for recording, place the cursor a few measures prior to the punch-in region, and you can safely correct the glitch without affecting the rest of the track. One limit to this technique is where there's a sustained sound like a ride cymbal along with the glitch. If there is no break in the music, and the punch-in just isn't right, try recording just the glitch passage to a new track. You can then select and cut the offending region in the original track. This new take is best done in the same session, so all the levels are the same.

Looping

Maybe that glitch is happening over a tricky part of the song? You can set a loop with the range tool to rehearse it. But let's review using the pointer tool to select a region. Place the pointer in the selected track at the beginning of the first measure you want to loop and strike the 'S' key to split the track. Repeat this at the end of the last loop measure, then click in between the two split points to highlight the region. In the main menu, go to Region/Loop to enable looping.

MIDI Tracks

You can import a MIDI track or record one from scratch in Ardour. Keeping the note values separate from the audio is useful for a couple of reasons: quantizing percussion and auditioning different patches to play a melodic part. And it's simple to set up. Go to Track/Add Track or Bus, and use the popup's second dropdown menu to specify MIDI. The default label identifies the track as a MIDI track.

By default, this new track is connected to MIDI through and will use the native Reasonable Synth as a sound generator as seen in the Mixer window. In JACK, connect your controller's MIDI out to MIDI Through and you're ready to record the MIDI track.

Now you can open any virtual synth, and assign the MIDI out from the new track in Ardour to it's MIDI in, under JACK/MIDI (click ardour to display the dropdown as in the screenshot below).

Connecting Ardour's MIDI out (left) to a virtual synthesizer (right).

In the Mixer window, set the input of a new track to the output of the plugin being played by the MIDI track, and arm this new track for recording. The plugin will appear under the Other tab (see below).

Yoshimi's output connected to EP input

A MIDI track can be imported like a wav file, and the same technique used to play it or record audio.

Fade-in and Fade-out

Mouse over the very beginning or ending of a track, then click and hold the handle in the upper corner - a curved icon should appear. Drag to define a fade-in or fade-out zone. Note, this technique also works in Audacity.

Automation

One of the coolest features of Ardour is the ability to automate track attributes like volume, panning, trim, and muting. Automation will appear in its own "lane" associated with a track. You will create a curve made up of control points (which you can add or subtract as needed). The four modes are manual (overrides automation), play (use the curve to control the parameter during playback), write (set the automation in real-time), and touch (hand-edit only part of the automation curve, leaving the rest alone). To see all of the automation lanes, just click "a" under the track name. The parameters have dropdowns set to "manual" - changing that to "touch" for the L/R (pan) automation lane made it possible to create the curve in the following screenshot by maniputlating the slider during playback. You can read more about automation in the Ardour manual - it can even be applied to instrument parameters!

Grouping Tracks

When a song has a large number of tracks, it may be necessary to apply the same action to a subset of those tracks. As you might have guessed, the "g" button next to the "a" button lets you create and assign groups, as well as what properties the tracks will/won't share.

Strings and Sinnah have been assigned to the "Pad Stuff" group, which was made bright green using the color picker we saw earlier. Grouping is also possible when first creating a track.

Creating a Bus and Inserting Effects

A physical mixer has auxilliary send and return "buses" that are typically connected to a rack-mounted effects unit and can be applied to individual channels, with the amount controlled by a pot. Thus the vocalist can sound like she is singing in the shower while the guitar remains dry. Ardour carries the metaphor through, as you may have noticed under "Track/Add track or bus". Let's say you have many hand percussion instruments on five or six tracks and want to apply reverb. Instead of putting a reverb effect on each track, you could create a bus with the effect you want, adjust the sound, and then use the sends in those tracks to apply it uniformly. This can be done pre- or post-fader. Here are the steps:

1. Add a bus under Track/Add track or bus
2. In the mixer, add an effect to the new bus by right-clicking in the blank area between track controls and selecting "new plugin" from the popup. Scroll to the desired effect and click on it.
3. Still in the mixer window, at the bottom of each channel that you want to apply the effect, change the destination from "Master" to your new "Bus In".
4. With the song playing, double click the effect and use its "Bypass" button to toggle it on and off to confirm everything is hooked up correctly. For testing, you might also want to crank up that effect's parameters to make the comparison less subtle as in the screenshot below.

Setting up a bus is a little bit of work, but not bad for something so powerful. Note that effects can be added per track without using a bus.

Additional Advanced Topics

It's out of the scope of this book, but video editing is possible within Ardour. You can rip the soundtrack from a video, view it over a timeline, even frame-by-frame, and make all the moves needed to create that Hollywood movie soundtrack of your dreams.

Right-click and hold in a track's charcoal area to browse and add effects. Here a flanger was added to the EP track.

Carla Alternatives LinVST and Airwave

There are two alternate ways of using Windows-only .dll VST plugins in Linux. LinVST will copy the Windows .dll file to a .so file, and they are stored together. A Linux DAW can then read the .so file via symbolic link. Unfortunately, this is only available as a Git repository. If you are not comfortable running a make file and addressing a large number of dependencies, LinVST is probably not for you. After a lot of work, and still unable to run the program, I discovered it still requires a Wine bridge, just like Carla. You can read more about it here: https://github.com/osxmidi/LinVst

The other choice is airwave, but it, too requires Wine. Source code is here:

• https://github.com/phantom-code/airwave/releases

Since none of these are part of Ubuntu, we won't cover this topic any further. One solution is to "go with what you know" - there is a handful of instrument plugins that run natively on Linux if you want to add to those that come out of the box (http://linux-sound.org/linux-vst-plugins.html also: sort by OS at vst4free.com).

Appendix

Troubleshooting

A lot is going on under the hood while making music on a computer, and so countless things can go wrong. There can be hardware idiosyncrasies, software updates that cause trouble, and any number of other glitches that would be impossible to cover in a single book. The good news is that someone else has probably encountered the same issue, posted it to the Ubutnu Forums, and already got one or more replies. https://ubuntuforums.org The Ardour manual is and extremely good resource as well: http://manual.ardour.org

Using the command line

When installing a program or troubleshooting in Ubuntu, it is common to run a command or series of commands by hand. You won't need to know what the commands mean, you'll just need to copy-paste them, one at a time (watching out for line breaks), then hit 'Enter'. But...first you need somewhere to type those commands! This is where the Terminal Emulator (know as Xterm on some systems) comes in. In the old days, a text-based "dumb terminal" was connected to a "mainframe" which is where the processing power was. When you open the Terminal window, you will be issuing Linux (UNIX) commands at a prompt - this is called a "command line operation". The prompt is usually the name of your computer or the current directory followed by a '$'. Instructions often include the $ to indicate the prompt, but should remind you to omit it when copy-pasting the command into the command line. To be sure you'll have "write permission", you should be logged in as the administrative user - the one you set up during the installation process. That's really all you need to know for the purposes of troubleshooting, but here are some common commands that might prove helpful, shown in courier font. Notice they are descriptive abbreviations (italcs). Square brackets [] indicated an option.

• • pwd - print working directoy. Shows where you are in the file system. • ls - list the contents of the current directory • ls -ls - long listing with more details on the files • ls -lsa - long listing including all "hidden" files (which start with a '.') • cd [path] - change directory to my home or a specified path (e.g. '$ cd /usr/local/bin') • rm [filename] - remove a file (substitute the target for 'filename') • rmdir [dirname] - remove named directory • mkdir dirname - make a directory called 'dirname' • sudo command - run 'command' as super user. You will see this in most instructions. • chown [user]:[group] [filename] - change ownership of a file to a given user. • chmod a+rwx [filename] - change "mode", i.e. give read, write, and execute priviledges to all users. Use with caution! This command gives univeral access to your file, making it unsecure. The chmod command takes many different arguments that can set permissions for everyone, just a particular group or users, or just the owner of the file. Also note: '.' is shorthand for "the current directory" and '..' means "the parent directory". '*' is the wildcard symbol - also use this with caution and make sure you understand what a command will do before using it.

It is also possible to edit files on your file system from the Terminal window using a text editor called "vi". I mention this because some help pages may instruct you to use vi. If you're not comfortable with vi, any text editing application will do.

Plugin Mania I love quirky VST plugins. One of the all-time champions is HG Fortune, whose left all of his creations on Archive for free use. Here is the "Nearly Forgotten Gems" archive (32 bundled plugins, multiple versions of some): https://archive.org/details/HGFortuneNFG

The following are not included in the bundle, but are worth checking out:

• • The Tyger Synth: https://archive.org/details/HgfortuneTheTygerSynth • Fortune Cookie: https://archive.org/details/HGFortune-FortuneCookie-2012 • Avatar: http://www.vst4free.com/free_vst.php?id=1036 • The Dream Machine: http://www.vst4free.com/free_vst.php?plugin=The_Dreammachine&id=1042

These synthesizers tend towards dark ambiance - some notes to help distinguish some of the HG Fortune plugins from one another appear at the end of this section.

Someone asked for links to the strangest VST plugins on Reddit (WARNING: foul language): https://www.reddit.com/r/edmproduction/comments/2qsh4d/whats_the_weirdest_vstau_you_know_of/

While we're talking about novelty synths, the PAL-9000 is hilarious: http://www.vst4free.com/free_vst.php?plugin=PAL-9000&id=2288

Some of my personal favorites are sampled instruments like Chau Gongs, Redtron (Mellotron M400S strings), Revitar, and OMB1 (bass). A couple of keyboard plugins to check out: MrTramp2 (everyone agrees it really sounds like the keys on Supertramp's "The Logical Song" - definitely adjust the settings to taste). Looking for an old-fashioned pump organ? Try Harmonium. Maybe you are into EDM? Firebird is loaded with contemporary patches and a bright, enticing interface (follwong page, top). All of the above are available on http://vst4free.com which has a Keywords search (top text menu, third link).

Super Spook Keys (groan) is a great example of the diversity and specialization of plugins. This Theremin by Simple Media has a lot more of the subtlety of the real thing than your typical keyboard Theremin patch. Hear it in action along with its other presets at the following link: http://www.vstplanet.com/News/2011/Super_Spook_Keys.htm

Simple Media's page is worth a visit (paid and free VST instruments, with an emphasis on strings): http://www.simple-media.co.uk/vsti.htm

Simple Media's plugins have gorgeous, unique graphics.

Pianos

As promised, some piano resources. The free Piano One is a good example of the trade-offs in sampling versus file size mentioned earlier. It's got shorter, 16 Bit samples in contrast to the 32 Bit notes of it's commercial version, NeoPiano, whose 32 Bit notes that capture the full note decay. Other features of the paid product are omitted. All of this adds up to a noticeable difference in sound quality; it may not sound exactly like the Yamaha C7 concert grand used for its samples, but it's still a serviceable piano that will run on older systems:

http://www.supremepiano.com/product/piano1.html

I've had some luck with Upright 1 from Versilian Studios. This piano is warmer than some real uprights. It might have a little latency on older systems, the GUI may crash, and it might not pick up the sustain pedal signal - but the 64 Bit sound is quite good, offering a distinctive upright sound.

http://vis.versilstudios.net/upright-1.html

A slew of different free pianos is available from Big Cat Instruments:

http://bigcatinstruments.blogspot.com/2015/09/all-keyboard-instruments.html

Some of the greatest pianists loved Baldwin pianos. I really like the sampled Baldwin baby grand of Big Cat's City Piano available at the following link with this cool blue skin.

http://vst4free.com/free_vst.php?plugin=City_Piano&id=2293

Free Piano from RDGAudio is more recent (2017) and has some layered sounds along with other controls (requires 64 Bit Windows 7). The KVR Audio site has many other free and paid plugins to browse.

https://www.krvaudio.com/product/free-piano-by-rdgaudio.

Continuous Velocity Piano by recording gear giant TASCAM is highly rated, and represents a clever approach to the size problem, spectral morphing. It runs a single sample through assorted filters to provide a great range of timbre. This is similar to Free Piano, but with far more options. The installer failed to run for me with an error message saying it requires Windows XP Service Pack 2. Maybe try running the standalone version. Once installed, there are some additional steps to get it to make any sound. Open the edit window and note the progress bar at bottom right - that shows the sample library is loading. Note - the dll file will load in Carla, but it will fail to load the sample library if you haven't run the installer. Make sure either Out or 'FX 1,2' is selected, and the leftmost dropdown should show CVPiano normal. You may need to "click to load" the first channel, then select a library from the dropdown. The CVPiano is a 7'4" KAWAI grand.

http://www.vst4free.com/free_vst.php?plugin=CVPiano&id=382

I hope this illustrates that results may vary widely when it comes to plugins in general and pianos in particular depending on your system and the instrument itself. The good news is there are many more available than covered in this short overview.

Still more plugins! http://vstmuseum.com/index/

Many synthesizers try to be all things to all people. And many VST plugins are emulators or "romplers" (sample players) of "vintage" synths. While it's amazing that every pre-existing type of synthesis is represented in one or another virtual instrument, often for free, after a point, there is some inevitable overlap. Even the GUIs generally follow a familiar hardware paradigm however artfully (or confusingly) masked by a GUI. By creating a suite of more narrowly-purposed plugins, no two of which look or sound alike, H G Fortune's instruments stand apart from the crowd. Unusual control interfaces that could not even exist in the physical world, randomizing buttons and ways to rapidly modify a sound all combine to encourage us to think outside the box.

By the time he passed away in 2014, he left behind an overwhelming 40 plugins. Here I review 16 of them, with an eye towards discovering just what each synth is "about". In many cases, there were two versions of the same synthesizer, which means this review covers more than it appears to (although the revamped version of a given synth may in fact be almost unrecognizable from its progenitor - feel free to make the comparisons yourself). While there is some redundancy, it is the case that these plugins constitute a suite serving distinct functions.

Alienoctis

Numinous ambient presets. The manual notes that dozens of "waveforms" are used for this synth, and it appears these are soundfonts, with an almost game-like GUI featuring three balls that you click and drag to alter the sound (or knob twist if you prefer). The presets are highly similar to one another - don't come here looking for lead synth sounds or anything percussive. HGF synths encourage play in the purest sense of the word, and the toy-like interface is a good example of this. Knowing what's to come, instruments that also have soft ambient sounds but are somewhat more versatile, I decided not to keep this one unzipped as redundant. That said, there were a handful of patches that got me started down the path of composing. HGF sounds are so rich that often a few notes that would sound uninteresting on, say, a piano, take on significance and could easily form a compositional starting point.

Alphatron

Interface looks like a traditional keyboard and panel synthesizer, and the sounds have plenty of analog punch allowing for strong lead and bass patches missing from most HGF concoctions. But you can find that with many other virtual synths. What sets Alphatron apart is an onboard sequencer. If the unusual control layout of the sequencer boggles you, fear not - call up any patch and hit "start" - that's right, the presets have built-in sequences, many of which are great for quick inspiration. Recommended.

Altair

This "SciFi Sounds Lab" is exactly that. Use it if you are making a science fiction movie. It's all here “ computer sounds, UFOs, spooky organs, theramin sounds, an more modern effects with names harkening Blade Runner, Jean Michel Jarre, and more. Very much a SFX generator, and the presets are wonderful even with no knob twisting. The glowing blue and orange interface looks like a mad scientist's lab video game. Because it is not very musical, I decided to uninstall and leave it zipped.

Anvilla Pro

The H G Fortune paradigm of the ability to mix and match - then tweak - two canned waveforms with a twist. A handful of "Lazy" buttons will alter any patch by doing the knob twisting for you. A quick tour of these settings with a plain vanilla (possible origin of "Anvilla?") patch shows that this paradigm is a clever way to get infinite never-before-heard sounds, as touted for all but the most preset-oriented synths, but sounds with some depth owing to effects and the waveforms themselves. Changing any one of the two source sounds has an even more profound effect on the overall layered sound, as might be expected. This is like cooking by matching flavors - lime and coconut, peanut butter and chocolate, etc.

The results are still often more akin to sound effects, and less "musical" in the sense that they do not lend themselves to playing a chord or a melodic line - many of the presets are not intended for those purposes. The few available lead sounds are uninspiring; likewise some of the organ sounds are perhaps serviceable, but I would first call up a typical tonewheel patch easily found elsewhere. Pads are good on this synth, but otherwise, it seems to be a bit of a pastiche of what you get from other HGF instruments, with the balance tipped in a brighter, happier direction than some of the darker, colder synths to be reviewed downstream. As with all HGF synths reviewed so far, there are some gems amongst these presets. One other fun feature is the back panel skin itself has ten presets. The default silver can be changed to a smoky gray, blue, deep red (which does not look very good behind the lighter blue buttons), sky (my favorite after the default) and some grainy galaxy and nebula images that don't work very well. Otherwise, the GUI is a plain panel of knobs with labels. This would be a good one to call up for inspiration, but probably not needed at my fingertips.

Arracis Gold

One of the first HGF synths I checked out, I had to give it a quick re-trial. Presets are almost exclusively one of two things - pads or sequences, the latter consisting mainly of pulsing sounds rather than a handful of looping notes. This may appear limited, but this is one of the HGF instruments where "what it does" matches the evocative name. Lots of shimmering sounds, many featuring two-note harmonies, bring to mind a mythical version of ancient Egypt (a quick search shows only a possible Dune reference, with a spelling difference). The distinctive gold interface helps set Arracis apart. For me, this one's still a keeper.

Alien Space Weaver (ASW)

Okay, I'll just quote the introduction to the manual and move on: Alien Space Weaver is a very exceptional synth as it is especially made for spacey or dark athmospheric backgrounds and FX sounds. One oscillator contains 75 very special samples i.e. fairly long ones being created from various images providing very spacey sounds from the start already. Thus play it slowly and let the sounds evolve. It's also been called the Eeriator...

We're in very familiar territory here. This really is a great atmospheric synth, and one of the larger downloads (probably owing to those fancy waveforms).

Atonoise

This one did not load for some reason. From the manual:

• Atonoise 2 is a widely enhanced version of prior Atonoise and is basically built around the modified Mystify processors of the Avatar ST VSTi Synth. Thus it can mangle up sounds to a great extend beyond recognition. It can be used on virtually any kind of sounds like vocals, drum loops, tracks and is even suited for deep sample processing if very few til no modulation is involved. For a more easy access and to give you some ideas of the capabilities a small set of internal samples (including vocals, drumloops & track excerpts) is used for the internal preset bank.

Avatar

More lush, cinematic atmospheres that "play themselves". Another interface with tons of knobs - four oscillaors. I should say a word about the patch names – they are wonderfully inventive in all HGF VST instruments, sometimes coined words. Lots of "space" this and "galaxy" that, in keeping with the sounds. Panning and delay are a big part of these soundscapes. One Avatar patch is called "Good For Intros" - that says it all. Some of these presets are like little movies unto themselves, one was called something like "Scene Three For Alien Movie". Herein lies a small problem - the names can almost dictate how the sounds might be used, just as the sounds themselves are so complex, often with pitch shifting, that they are not what we normally think of as "musical". This VST comes with a handy virtual keyboard, a feature that seems to have been added on to several HGF pro offerings at some point.

Laserblade

Where several of the above synths are weak on "musicality", Laserblade has sounds labeled as bass, synth, lead, and pad - while ranging in quality from interesting to cheesy, they certainly could be used to play a melody, bass line, or hold down chords. One feature that stands out is a "metalize" section. I'm not sure what this does, but some of the presets have a metallic timbre, and the GUI itself appears to be made of polished meta. As I mentioned, it's easy to find demo tracks of this synthesizer and many of the other HGF instruments. Lot of sci-fi film references in patch names, although sounds do not necessarily correspond.

(Z) Percumat

From the manual:

• "This is a versatile Rhythm machine for backing drums percussion so definitively not an 808 or 909 type thingie. It features 6 instrument parts / slots to choose from 512 inbuilt drum & percussions sounds. There are two step sequencers one for setting up the beat steps in groups of 4 x 8 steps (or 4 x half a bar) labeled A1, A2, B1 & B2, while the 2nd sequencers on the left allows you to control a sequence of the 8 step beat groups in 16 steps. Thus it is easy to get variations without having to program complete 16 step bars. In addition to that there is an Auto Track Mute feature for tracks 4, 5 and 6 to have one or two tracks muted for a certain range." Plenty of nice presets to get you going fast, includes world beat, a few alternate time sigs, etc.

Protoplasm

Gray GUI with art deco lettering. Three oscillators, High- and Low-pass filters, three LFO, sample and hold, delay, VCA mix section. Familiar ability to layer two soundfonts at once. Lot of patches named after planets. This may have been "proto"type for some of the space ambient synths to come later.

Shuniji

Maybe I am missing something with Shuniji pro, but it seems like more of the same. A few sounds are vaguely eastern-sounding, and this comes with a bar-graph supposedly for editing waveforms. Sounds tend to be muted. Another blue and gray GUI. I give it a "meh" and will not keep it installed.

Silver Orbit

Pretty typical HGF, another gray panel, this time with a ball interface in the Gui that can be animated. Primarily what I would call "goofy" sounds, unlike the darker long delay sound of similar synths. I don't dislike any of these synths, but this is one of my least favorite thus far. If someone had only this VST, they would probably get frustrated soon.

STS-26 Protoplasm

This was one of the first HGF VSTs I tried out, and was curious to see if it held up as "best of breed" for space ambients. From the picture of the galaxy on the "dashboard" to the four waveforms, this really is the luxury model. There are some credible lead sounds, but again pads and backgrounds are the strength of this synth. The STS strings patch rivals any synth string patch on any keyboard I can think of and is worth keeping this VST in itself. Many of the presets actually play little melodic motifs, again encouraging a different approach to composing, one of collaborating with the patch designer, effectively. And why not? If you don't like the chosen notes, it should be simple to mute that oscillator. If there was only one ambient HGF synth, I think I would still chose STS-26.

Swamp

Two versions of Swamp are great examples of idosyncratic VSTs - ambient, but darker and "swampier" than the other offerings. Electronic frogs and cricket sounds inhabit this voyage into a creepy otherworld. I've used this on a full project because it's like nothing else out there. Recommended to check out especially if you like 'em strange.

XWOF-4

Just when it appeared Mr. Fortune had nothing else up his sleeve, along comes this amazing electronica looper. If, like me, you are not very good at concocting beats, and at least occasionally like the idea of "press play and off to the races", this is for you. In fact, the synth has "play" activated as soon as you plug it into your rack. These segments are often longer than the memory limited two measures of old school drum machine "rhythm patterns" and the sounds go way beyond kick, snare, tinny hi hat, and toms. In fact, so much is going on, that these might sound like completed songs in themselves on first hearing. I did not read the manual, and the front panel does not have anything that looks like a step sequencer, so it's not clear if this is more than a loop library. Either way, this synth is, to my mind, distinct from the others in that it is more firmly in a subgenre (electronica/dance) and addresses the rhythm rather than pad backgrounds. Great to have in the arsenal, even if you're not a DJ.

(Z) Plutonia

Leads, leads, leads. This instrument has a smaller front panel and fills the void of lead patches from the HGF fleet of plugins, while still offering some breathtaking pads and wiggy special effect sounds. But let's be honest about highly complex sounds that have to be "held out" to even hear everything they do. The more bizarre they are, the more rare the situation where anyone will ever call them up. If you are writing a tuneful piece of music, atmospheric pads alone just won't cut it. The lead sounds here are on par with U-He's free offerings such as Zebralette, and things like warped, delay-rich bells are also quite similar in quality and approach. Many HGF bass sounds strike me as too busy or fuzzy to be functional, but some of the bass sounds on Plutonia are more punchy. Plutonia is not only a welcome addition to round out the HGF collection - it's lead presets have enough of their own character to compliment others in your library. Another keeper.

Conclusion

Which ones should you install? That depends what you want to do. These are all good, but I find some more inspiring than others. Why not play around with, say, Altair, even if you ultimately uninstall it? I hope this was a helpful overview of the synths the late Gunther Fortune most generously made freely available as his legacy to musicians everywhere. To audition them, you can find patch demos on YouTube and whole recordings at the Archive link for these instruments.

UbuntuStudio/AudioHandbook/BasicRecordingForMusicians - Community Help Wiki

Basic Recording For Musicians

Audacity

A number of recording applications are available for Linux. Because this book is about multi-track recording, we will focus on two, Audacity and Ardour, both of which can be found on the main "Audio Production" menu. If you mouse over Audacity, the simpler of the two, it says "record and edit audio files", but this belies the fact that you can add as many tracks as you like. Anyone who has used a tape recorder should feel at home with Audacity once the audio input is configured.

Be sure that JACK is running and you have a soft synth like Hydrogen launched prior to opening Audacity. From Audacity's Edit/Preferences/Devices menu, configure it to record from Hydrogen as in the screenshot below.

Back in the main menu, select "Track/Add Track", click the record button, and you should see the waveform appear as you play your drum track or other synth. Assuming all went well, here are some frequently-used actions:

• • To split a track, place the cursor where you want to make the edit, then go to "Edit/Clip Boundaries/Split" or use the Ctlr+I shortcut. You can then highlight or drag one portion of the track for further editing. • The magnifier tool (zoom) is helpful when making fine edits. • If a track sounds a little weak, either use Effect/Normalize or Effect/Amplify to boost the gain. • Effect/Pitch does a good job at pitch-correction, although some guesswork and using your ears may be involved. • To apply an effect, just highlight a track or region, then select the effect you want from the dropdown menu. • At mixdown time, don't forget to experiment with the pan control found below the Mute and Solo buttons.

Although we are primarily concerned with making digital recordings that tend to be very clean, note that Audacity's noise reduction, also found in the Effect menu, is remarkably good for a project like cleaning up digitized cassette tapes. It works by sampling a bit of the noise, then removing those frequencies throughout the recording. It even provides a way to subtract the noise more or less aggressively, in case you start to hear the filtering encroaching on parts of the signal you want to retain. We will see other tools that can target problem frequencies when we discuss mastering, but Audacity's noise reduction is simple to use and produces impressive results. Another strength of Audacity over other recorders is that it can export to any format imaginable. It may not be your primary DAW, but Audacity has many specialized uses. The manual (under Help) covers all of Audacity's capabilities clearly and succinctly.

This is as good a time as any to suggest http://freesound.org for all manner of sound effects (and a fair number of loops) that you can import directly into any recording project. If you are not familiar with that site, I suggest you pop in a bookmark here and go check it out. If you are making a test recording in Audacity, take a moment to try importing a file from freesound.org into its own audio track in Audacity as an exercise

Ardour

If you have used a Digital Audio Workstation (DAW) such as Ableton, Cubase, Cakewalk Sonar, Logic, Reason, or FL Studio, then you will be in familiar territory with Ardour. As with most freeware and shareware, Ardour may not have all the latest bells and whistles, but make no mistake - this is a full-featured DAW, and will give you professional-quality results. Personally, I like it that open source software evolves more slowly - it is less susceptible to feature bloat than commercial products. Ardour has two main windows, an editor and a mixer, shown below. Ardour's track editing view has familiar features - transport and editing tools, clock and measure readouts, metronome, and a timeline where you can set the meter, tempo, and place markers. New tracks are added below "master" in the above screenshot.

Ardour's mixer window, above, not only sets individual track levels, but also allows for inserting effects pre- and post fader. Input from JACK can easily be assigned via the button just below any track's name.

Above: the mixer button with the asterisks (top left, 2 just above Growler) was clicked to reveal the pop-up (shown) where the track input (green diagonal) can be connected to the Hexter plugin, found on the "Other" tab at bottom of the pop-up's vertical lefthand menu. Clicking the Rec button turns it pink, indicating the track is armed for recording.

Once the input is set, return to the track view tab, hit the red "record" button in the transport section, and recording will start as soon as you click the "play" arrow. On both Ardour and Audacity, the space bar can be used to start and stop playing. Ensure that Ardour's Master outs are connected to "System" in JACK, return the cursor to the start of your recording via the left-arrow transport button, and play back your first take.

Now let's take a closer look at track settings. In either the main window or the mixer, you can change a track name by clicking on it. Ardour automatically assigns each track a color, but you can alter that and other track attributes from a menu that appears on clicking in a blank area near the track name in the editor window

Next to the record enable button on each track are buttons for mute and solo ("m" and "s" respectively). We will discuss the bottom row of buttons in the chapter on advanced recording. The pointer tool (green button in image below), can be used to drag a region to a new location in the timeline. Clicking and holding the edge of a track with the pointer tool will resize the track. To start playback in the middle of a track, click in the area above the master track, then hit the space bar.

Ardour's toolbar includes selectors, zoom, and note editors.

To the right of the pointer icon in the toolbar is "region mode" which can be used to select/move regions with the cursor. There is also a "smart mode" to imbue the pointer tool with this ability. I have not found myself using these alternate modes much, but you should try them out to see how they alter the cursor's behavior. It should be clear what the Grid and Beats menus do (just try them). The Playhead menu sets the starting position of the cursor to either wherever the mouse is, an active (selected) marker, or the beginning of the song. This feature can be useful when working on longer and more complex tracks. More playhead options are under the main Transport menu. Hydrogen does not play well with JACK running, but recall that you can export a Hydrogen song to a wav file. To import a wav file into Ardour, use Session/Import to navigate to the file; open it, and it will appear on a new track. It is best to learn the keyboard shortcuts as soon as possible to avoid return trips to the edit menu. Copy, paste, and undo are the same as in a typical word processor. To split a selected track, place the cursor in the desired spot (you may need to zoom in with the magnifier tool first), and hit 'S'. If a track has many isolated regions, sometimes they all need to be moved at once. This can be done by selecting the track and using Edit/Combine, which will also prevent inadvertently moving part of a track and allow for making global changes like normalization. Ctrl-up or Ctrl-down will move a selected track up or down the track list, and click-dragging the track's edge - i.e. within the list area - will adjust its height.

To export a track, first make sure the start and end markers are where you want them and return the playhead to the start marker. Then select "Session/Export to audio" from the main menu and follow the instructions from there to pick a destination directory for your file. Tracks that are muted will not be included in the export. Note that you can export the whole song or export individual "stems" (tracks). The latter is very useful when collaborating with another musician or producer/engineer.

Other DAWs for Linux

If Audacity and Ardour are not to your liking, there are other options. LMMS is available in the Ubuntu Software Center and is a simple install. It is somewhere between the two recorders we just looked at, and has a colorful, quirky layout. LMMS boasts native support of VSTs, and comes with some nice pre-installed plugins. It is not as full-featured as Ardour, but a bit less complicated and free. https://lmms.io

Renoise has a $75 license fee. It uses a unique vertical scrolling tracker and uses QWERTY keys as the keyboard. Check out the tutorial video at: http://renoise.com/products/renoise

You can get Reaper for $60 (60-day free trial). It's sleek graphic design recalls, well...Ardour. Reaper also supports VST plugins. I have never used it, but there are a number of video tutorials on their site: https://www.reaper.fm

Bitwig, Computer Music's DAW of the year for 2017, will set you back $300. Always check the hardware requirements before you buy any software. The design looks modern with a lot of customization efficiently embedded in multi-purpose controls. Glancing at the video tutorials suggests a big learning curve is in store. But it is popular and it runs on Linux.

Don't forget to read the latest news about Ardour. Here is a theme pack that includes themes called "ableton-like", "blueberry-milk", and "cubase-like": https://community.ardour.org/node/13685 if you are more accustomed to one of those DAWs or just don't like the default skin. [Note - I have not tested these skins] https://ardour.org/whatsnew.html

Who knows what options will come down the pike? You can even install a DAW on a tablet (check your available space first!). It is probably a good idea to find one DAW that suits your needs and stick with it for a while. While it's true they all have things in common, as this book illustrates, there's always the buried menu item or secret command. Why learn the ins and outs of many DAWs when they all give you a similar result? Also, in making comparisons, bear in mind we have only scratched the surface of Ardour's capabilites in this chapter. Ardour's online manual is far more thorough and very well-written.

We have covered the basics of multitrack recording in Ubuntu Studio. Now let's have a look at non-native plugins to broaden our selection of sounds and instruments.

UbuntuStudio/AudioHandbook/CreateSoundFontSwami - Community Help Wiki

Creating Your Own SoundFont with Swami

Swami is available in the Ubuntu Software Center. But first, you will need some samples to import. Hook up a mic to your soundcard, and record individual notes, percussion hits, or sound effects using Ardour and save in wav format. If you are recording individual notes on an instrument, be sure to include the corresponding keyboard note value in the file name for ease in mapping later. Of course, it's not necessary to make new samples - for the purposes of learning to use Swami, any short wav file will do. In the example below, I used sound effects from freesound.org.

Now install and open Swami. Select File/New soundfont, name it, and click the arrow next to the green SF2 icon to see the soundfont's folders. Right-click the Samples folder and upload the wav files you gathered via "Load Samples" menu option. Once the samples are in the folder, highlight them one-by-one, and assign them a Root note in the Properties tab (bottom center of window). If these are tuned samples, make sure the root note corresponds to the pitch of the sample. Now right-click the Instruments folder and create a new instrument. Then simply drag the samples you want into that instrument. At this point, if you press the keys on Swami's virtual keyboard, things won't sound right because all samples default to play over the entire range of the keyboard. Click on the samples within the instrument and narrow the corresponding green bar to agree with the range of keys over which it should sound.

Finally, create a new Preset, and drag the instrument into that Preset. A Preset can have multiple instruments, but at this point, the soundfont is ready to play. Just save it in a dedicated soundfont directory with the .sf2 extension. Note that Swami has a wave editor that can help find the loop point for samples you want to play continuously as long as a controller key is depressed.

Open Qsynth to test the soundfont as an instrument. First import the soundfont to Q1 or Q2 via "Setup/Soundfonts/Open" - navigate to the soundfont folder you created and import the new soundfont. In the Channels tab, double-click next to the MIDI channel you wish to assign to your soundfont, and pick the soundfont from the pop-up list (since this is your first soundfont, it should be the only one on the list!) Make sure all connections are correct in JACK, with the keyboard MIDI going to Qsynth and Qsynth connected to Audio/System.

A soundfont comprised of horror movie sound effects loaded to Qsynth2, set to MIDI channel 1.

For a video tutorial of Swami with a few more details, such as making your soundfont velocity-sensitive, see: https://www.youtube.com/watch?v=8a3kS9b9gRg

General MIDI

There is a standard mapping of sound banks in MIDI, so that someone composing for, say, a computer game could create a MIDI track and know that the bass line would be played back as a bass sound. If your soundfont has multiple instruments, this could prove a good way to arrange them. You can find the list in the back of this book or here: https://www.midi.org/specifications/item/gm-level-1-sound-set.

UbuntuStudio/AudioHandbook/GettingStarted - Community Help Wiki

Getting started

Gear on a Budget

When I was a teenager, I started just playing the piano. I saved up my lawn mowing, snow shoveling, and leaf raking money to buy a little combo organ, and could only dream of owning a real synthesizer. I used gig money to modify the organ with one big purchase – an Electro Harmonix Phase Shifter! Who were the lucky kids who could afford that Concertmate MG-1 (made by Moog!) on display at Radio Shack? 'Teenaged me' would be gobsmacked with capabilites of soft synthesizers. Things got a little better in the 80's, but most weekend warriors were still not going to purchase more than one or two keyboards, meaning we would never get past trying out some boards at the music store. Now there seem to be more emulators (some highly accurate, others less so) of more vintage keyboards than we'll ever have time to play. But could 'teenaged me' afford to “go digital” today? With an eye towards this question, let's have a look at the minimal gear outlay for running Ubuntu Studio.

• • Laptop (requirements below) - $35 to $130 • Outboard sound card - $40 new [Behringer U-PHORIA UMC22] • MIDI controller - $40 • USB and other cables - $15 • Headphones - $20 • Optional: sustain and volume pedals, microphone, and monitors or amplifier, stands • Internet access – try WiFi at your local library for downloading software as-needed (free)

So the bare minimum outlay, assuming the two pricey items are purchased used, would be around $165, certainly below $200 (estimates based on web 2018 web searches). Considering what 'teen-aged me' could charge for shoveling snow these days, I'd say that's well within anyone's grasp. Of course, you can spend $300 on the sound card alone, and certain 'designer' headphones can cost as much as $350. If you buy everything new and consumer-grade, think in the range of $700-900 to completely outfit your bedroom studio from scratch.

How to find out if your old laptop can run Ubuntu

Linux does not run on every system. Fortunately, there are convenient web sites where you can look up your hardware to see if others have successfully installed Linux. The following resources also have installation notes:

Linux on Laptops http://linux-laptop.net Tuxmobile http://tuxmobil.org

For the first draft of this book, I used a decade-old Dell Inspiron 1420 laptop. Most used laptops have more horsepower than that, and you'll need it to run a current version of Ubuntu Studio. If you also have an ancient relic, all or most of what follows should work for you. Whatever hardware you end up with, check that it meets the requirements on the following page. In Windows, you can get the information via Settings/System/About.

System Requirements

Before running the installation, you might want to check that your computer has the minimum requirements.

• • 2 GHz dual core processor • 2 GB RAM (system memory) • 25 GB hard-drive space (Ubuntu Studio's footprint is much smaller, but you'll need extra space) • VGA monitor capable of 1024x768 resolution • Either a CD/DVD drive or a USB port to install and try out the operating system

Running Ubuntu from media

By now you should have a computer and soundcard. If you're still unsure about whether Ubuntu will work on your system, or just want to give it a test drive prior to committing, it's possible to run the system from either a DVD or USB drive – this is one of the startup options on the same disc image we'll use to run the full installation. The steps are:

• • Download the Ubuntu Studio ISO file at https://ubuntustudio.org/download • Burn it to a CD/DVD or bootable USB stick (DVD image is about 2.6 GB for version 16.04) • Restart the computer with media in place and follow the installation instructions

The Ubuntu Studio site has further installation instructions and details, but the process is self-explanatory save one step: changing the way your computer boots up. To boot from a DVD:

1. Back up your hard-drive. In particular, save any files you want to the cloud, USB stick, or other external drive.
2. If using a thumb drive, use Unetbootin from unetbootin.github.io to store the image, then follow all the steps, selecting “boot from USB” if that option is available.
3. Restart the computer. Before Windows comes up, you will need to hit one of the 'function' keys along the top of the keyboard. Usually it is F2 – check your PC manual. This will bypass the normal boot sequence and reveal a window that provides various options including where to start the boot process itself. The menu that comes up is text-based and you navigate it using the arrow keys to make a selection, then just hit 'enter'.
4. Insert the thumb drive containing the Ubuntu Studio ISO image you created.
5. Restart the computer again – this time it will read from the USB stick (thumb drive).
6. You will be presented with the choice between running Ubuntu from the USB stick, a clean install or a “dual boot” which would allow you to start to either Windows or Ubuntu. Run it from USB (or DVD).

Installing Ubuntu Studio

After having a look at your new system from media, restart again with the DVD still loaded, and pick the type of installation you prefer. A “clean install” will erase everything from the old computer, but this is recommended. We won't cover the dual-boot scenario here, other than to say you will need to know about creating disk partitions if you want to set it up that way. From here, there are not a lot of steps, but allow yourself 30 minutes or so as there are a lot of files to transfer. Here is what to expect:

1. Select English and do download updates during the installation.
2. Unselect “install alongside Windows”.
3. Select location and language for the keyboard layout.
4. Enter your personal name, and password. Note this will be the administrative password.
5. The 'computer name' is the name that will appear on any network, kind of a nickname, so accept the default or make it anything you prefer.
6. 'Encrypt my home folder' is useful for laptops in case they are lost or stolen.
7. Once the installation is complete, click 'Restart Now'.
8. Remove the DVD or thumb drive when prompted and hit 'Enter'.

Now you should take a moment and check out the non-musical software that comes with your new operating system, noting there is nothing mysterious about it. Ubuntu follows the standard concept of a launcher with icons that open assorted applications. A screenshot of the menu is on the next page. Start by opening Office. This book was written using Libre Office Writer. You'll notice it looks a bit like Word from a few years ago. Open a new document (File/New/Text Document). Enter some text in the white space and highlight it with the mouse. Guess what happens when you click the very large letter 'B' in the toolbar? I hope you can take it from there.

Before we leave this section, familiarize yourself with your desktop's software manager. There you can find a library of applications by category, with user ratings – almost anything you can imagine is available, and programs self-install at the click of a mouse. Have a look, play around with your new computer, and when you're ready, we'll do the finishing touch of setting up the sound card.

First, all of the hardware connections need to be made. Connect the MIDI controller and the outboard sound card to USB ports on the laptop. For now, you can connect headphones to the sound card, being sure to set the volume level relatively low and keeping them off your ears until we're sure the levels are reasonable. If you have speakers, connect them directly or via mixer now. Many sound cards and controllers are powered via USB, so the only thing you may need to plug in is the laptop. Note that your monitors should be off or volume set to zero when powering down the laptop. If you want to record an instrument, that usually goes into the front panel of the sound card. Be sure to consult the sound card's manual for appropriate settings. In general, “Pad” is for boosting the signal from a microphone. There might be an additional switch between “Line” and “Instrument”. The latter should work for electric guitar. Pots may need to be adjusted for different input sources.

The author's launch menu contains some items such as Wine that we'll add later|

Connecting a Sound Card With JACK and Patchage

The program called JACK is Ubuntu Studio's nerve center. From the launcher, click Audio Production/QjackCtl. Click Setup/Settings/Advanced to show the window on the following page. There's good news and bad news. The good news is that the default settings should work as-is for most sound cards. The bad news is that if they don't, it may be difficult to find specific instructions to tell you what works for your particular hardware configuration, and you may end up finding it by trial and error. On my system, there are seven options under input and output. The first time I tried to connect my sound card, using an earlier release of Ubuntu Studio, it took over an hour and some poking around the user forums. But in later releases, it was plug-and-play.

Under Parameters, I chose Alsa, Realtime, and the default Sample Rate (44100) Frames/Period (1024) and Periods/Buffer (2). Latency is grayed out at 46.4 msec, as I choose the low-latency option (recommended). Although I have a 64-bit processor, I have experienced some trouble running 64-bit programs under Windows in Ubuntu – we will come back to that point when discussing Wine and Carla in chapter 5. With luck, your system should be ready to go now.

The JACK advanced settings screen – this may or may not work for a given set of hardware. Details on the rig used for this book are in the appendix.

Making connections in JACK is covered in the next chapter. For now, return to JACK's main panel and try the Connections and Patchbay buttons. A good workflow is to set up Connections, then go into Patchbay and store a given configuration that you might want to call up again when working on a particular style of music. There isn't much to do in either of these windows until we open other applications. IMPORTANT: one last preliminary step will help later - see this link: http://manual.ardour.org/setting-up-your-system/setting-up-midi/midi-on-linux/

Ubuntu Studio Audio Configuration

In current Ubuntu Studio releases, Ubuntu Studio Audio Configuration is the main interface for configuring low-latency audio and JACK compatibility. Full documentation: Ubuntu Studio Audio Configuration.

Patchage

NOTE: Patchage is no longer part of the current Ubuntu Studio workflow. Carla can be used for graphical patchbays and routing.

• Patchage allows you to drag items around the screen to better visualize their connections.

You can use it to hook things up, as well. We're not quite ready to use this, but here's a preview.

Here a MIDI controller is connected to a amsynth, a soft synthesizer's MIDI input, the Hydrogen drum machine and amsynth's audio outs go to the system output, which we've already configured in JACK to use the outboard soundcard.

The audio generators depicted above are introduced in the next chapter, so read on!

UbuntuStudio/AudioHandbook/MixingMastering - Community Help Wiki

Mixing and Mastering

You've already been mixing - adding effects to tracks, adjusting faders with relation to one another, and so forth. Mastering is the final touch that helps make all tracks on a CD sound uniformly clean and balanced. Mastering includes frequency analysis to boost some parts of the spectrum that may be getting swamped, and notch out frequency spikes. It's an art unto itself. In fact, top musicians with years of studio experience tend to leave mastering to professionals. It can't hurt to at least understand what mastering is and how it differs from mixing, though. For the purposes of most people reading this book, an excellent mix may not require much mastering work, if any.

Earlier, I suggested normalizing a track that had a small waveform. Now I will take that back because normalizing tends to leave little to no "headroom" - the track is now very loud, so loud that if you apply compression, it will clip. Clipping is when the level meter goes into the red, and can result in horrid distortion on playback. Compression narrows the difference between loud and soft sounds in a track, hence allowing more room to increase the gain before the track clips (because the peak volume is lowered). This leveling has the effect of adding crystal clarity and presence to just about everything. Once you apply it, you may find yourself wanting to trim back those faders below zero Db! But that's a good thing, because it shows the signal-to-noise ratio is improved.

You will also see limiters in the list of audio processors - these do essentially the same thing as compressors, only with a high ratio and faster attack time. Sometimes applying a low- or high-pass filter can quickly eliminate frequencies you just know are irrelevant and possibly muddying a track - think piccolo or bass drum. While the timbre of some sounds such as the human voice can rely on harmonics over a broad frequency range, for other sounds a filter might be the right tool, especially if there is a glaring artifact showing up. These processors can be applied to individual tracks and/or to the whole song. In the Mixer, click on that blank region above the fader of any track or the Master track and select plugins/plugin manager. There you will see dozens of pre-installed effects and processors, many of which are frankly redundant. Notice the ability to favorite - checking that off will add the current effect to a short list under 'favorite' plugins the next time you add effects. I recommend starting with Calf Analyzer to get a view of levels across the spectrum. You can then deploy an equalizer or other tools to tweak those levels, but some caution is warranted. If you just go by your ears, you may be deceived by whatever monitors you are using, especially headphones where one is tempted to overcompensate the low end. A conventional piece of advice is to play back over a few different speaker systems. Also, trust the 'scope! The best way to understand mastering is to see it done live. Here is a great video on the topic from YouTube channel Mastering Monday, that includes a list of gorgeous free processors to try out: https://www.youtube.com/watch?v=FzNweEPg-2U

These did not all run on my system, but I liked Bluecat Audio's FreqAnalyst, and Tokyo Dawn Productions' Slick EQ, which includes saturation, a way to add a bit of warmth to digital recordings. Having tried out a few of these tools, my favorites list ended up with mostly standard Calf plugins. They come with an intuitive GUI and get the job done.

Mastering is an art, and getting the mix just right on a complex recording can be vexing. Really doing the subject justice is beyond the scope of this book. Please check the library, online resources, and the electronic music section of your local bookstore for more information on this very deep topic.

Overview of Out-of-the-box Instruments and Effects

Sound Generators

Start up QjackCtrl, then from the main Ubuntu menu, select Audio Production/Sound Generators, to see a list of pre-installed virtual instruments.

A list of eleven plugins appears (far right menu), with “Extra Sound Generators” at the top. We'll start with Hexter, Yamaha DX7 emulator that is also reminiscent of an early eighties Casio keyboard. Click on Hexter, then in JACK, click “Connections”. Go to the audio tab and connect Hexter's audio output to System by click-dragging a line between the two (see screentshot below). Use Hexter's “Send Test Note” button to check that the audio connection is working (bottom of left panel in following screenshot). If there is a problem, check the volume levels, then review JACK's configuration. Next, use the MIDI tab, open the left and right dropdown menus (here labeled “aj2”) to connect your controller's MIDI output to Hexter's MIDI in by drawing a line between them – drawing in either direction will work.

In Hexter's clean interface, it's easy to find a patch, and the patches are familiar sounds like marimba, clavinet, and synth brass. Screenshot 3.2 shows the surprisingly punchy patch, Growler, selected – be sure to give it a try along with other Hexter patches.

You can connect the other instruments in JACK the same way, but some of them may require additional setup, including connecting the MIDI out from your controller, which may appear in JACK's ALSA tab under the aj2 drowdown menu rather than under the MIDI tab where you would expect to find it. Let's continue the tour with an eye towards making sure everything plays.

Aeolus is a pipe organ emulator whose gorgeous sound compensates for a notably drab Graphical User Interface (GUI, pronounced “gooey”). When you launch Aeolus, all of its buttons flash in sequence. On older versions of Ubuntu Studio, it was necessary to install an additional helper program to run Aeolus. There is no default sound, and you must click “Recall” to get to the first preset. Depending how Aeolus is set up, you may notice that enabling and disabling some stops doesn't change the sound. Clicking on the MIDI button opens a grid where you can assign a different MIDI input channels to manuals P, I, II, or III. Remember to set the MIDI send channel accordingly on each controller (assuming you have more than one tier of keyboards).

For what it lacks in pizazz, the rest of Aeolus' operation is clear – use Prev and Next to page through a handful of presets. You can make fine adjustments to tuning, tremelo, and swell via the “Instrum” button, and “Audio” has sliders for volume, delay, reverb, and a few other parameters.

Pictured below is synthv1, an unassuming polyphonic analog synthesizer with 28 presets and a convenient waveshaping interface that allows you to sculpt the sound by clicking and dragging. It's possible to add nodes to the graphs as well. Connect it in JACK and you will see it has the classic fat analog sound. If all the knobs and initials appear daunting, please refer to chapter 10 for an introduction to creating sounds with any synthesizer.

Ubuntu Studio comes with three more “gray panel” synths pre-loaded: samplev1, drumkv1, and qsynth. See following screenshot.

Drumkv1 (top left), Qsynth (top), and samplev1 (bottom) share a common look and feel with synthv1. Qsynth is a soundfont player. Somewhat of an older format, soundfonts are a convenient way to package samples and map them to MIDI note events, effectively building your own instruments. Qsynth does not come with any preloaded soundfonts, but there are many resources for free soundfonts online. Two different patches can be loaded and triggered simultaneously to create a layered effect, using Qsynth1 and Qsynth2. Drumkv1 and samplev1 also require wav files to be imported. We'll look at importing sounds to Qsynth when we cover making your own soundfont. For now, let's note that samplers represent one way to get high-fidelity instruments (with some trade-off between sample size and quality) and continue the tour of out-of-the-box plugins. Amsynth has a brighter, almost harsh sound compared to Qsynth. This one is also polyphonic and comes with over 20 banks, each containing tens of powerful presets. The virtual keyboard may crash amsynth, but other than that, it's stable and quite an analog beast. This brings us to one my favorite native Linux synthesizers, Yoshimi. It boasts a simple interface and its sounds are a step up from Hexter, including some of the best bell tones you'll find. Yoshimi's virtual keyboard works without needing to enable it in JACK. To try the onboard effects, use the “Insertion Efx” tab and select “Master Out”. Under “Panel” (next to the pink reset button in the screenshot below), you can set up to 16 MIDI channels with different sounds. To get even more soft synths for Ubuntu Studio, first try “Audio Production/Sound Generators/Extra Sound Generators” - you should see a dropdown list of additional plugins to try out. Some of these cover similar territory to the ones we've already tried out, some may not have the best GUI. A handful more are listed in Ubuntu's Software Center – of those, don't overlook FOO, a bright red electric organ emulator. Here is a page that lists 73 synth plugins that run natively on Linux: http://linuxsynths.com/index.html. But...there are more free plugins for Windows than you could ever download, and only two programs are needed to run them (see chapter 5). Ubuntu Studio comes with the Hydrogen drum machine pre-installed – it's in the main “Audio Production” menu. This is a fairly deep program, so I recommend taking the time out to review the User Manual found under the Info tab. If a drum machine is any good, it will perforce be complex, as there are so many facets to creating a rhythm track. The good news is that most drum machines take similar strategies to addressing this complexity. You need a way to pull in sounds and organize them as a drum kit, a way to create patterns for the various parts of a song - intro, A, B, fills, coda, etc. - a way to tie these together, and, if we're lucky, save and export in multiple formats. Transport controls for real-time recording, and a grid for step recording (where events are added graphically via mouse click), and quantization (to keep individual hits where they belong), round out the basic functions to look for in any drum machine. The main distinction between programs is how user-friendly (or user-hostile) they are, and by keeping the GUI simple, Hydrogen excels in ease-of-use. The main menu has a slick LED clock, transport buttons, tempo selector and buttons to open a mixer (used to adjust the balance between sounds in a kit, if needed) and the instrument rack. Try the [+/-] increment/decrement buttons next to the BPM readout – this is how to adjust the tempo. If you are recording in real-time, the speaker icon just below [+/-] toggles the metronome, so you can record to a click (these three buttons are stacked in the middle of the following screenshot). Hyrdogen's main menu Directly beneath the main menu is the song section, where patterns can be chained together. The next screenshot shows a song that uses five distinct patterns, labeled on the left menu. Clicking a box in the grid turns it blue for a given pattern. So the four blue boxes next to pattern 1 will – you guessed it – play that pattern four times. And so on for the other patterns. Note the loop button in the transport window will keep the song playing if you have all the parts and don't feel like copy-pasting them. This can be good for real time recording and live performance, as we'll see in the next section. Before creating a song, you'll need to make some patterns. Open and save a new project. Clicking in the pattern grid will leave a black dot where an event should be triggered. You can work on this in real time by enabling looping and turning on the click in the main menu as mentioned earlier. Work your way up the kit adding and removing triggers by clicking. By creating a very simple pattern at first, you can then copy it to introduce additional parts. This will come in handy as you stitch the patterns together in the song editor. As you can see, I made two copies of Pattern 1, displayed as Pattern 1#2 and 1#3. Pattern 3 is this song's ending, a tom roll and cymbal crash. Hydrogen's pattern editor. Note the mute and solo buttons next to each instrument – these button might be used with looping enabled to add variety to beats during a live performance. The last panel has quite a few goodies in store – a way to edit the sound of individual instruments, and best of all for those of us with an insatiable appetite for sounds, a varied library of kits that can be swapped in for a given pattern. Not only that, you can upload your own sounds. Merely changing the kit can have a profound effect on a drum pattern's sound. Hydrogen is a highly adaptable workhorse of a drum machine with a GUI that is more intuitive than most other free drum machine plugins. Controls for editing instruments and changing out the drum kit (Sound Library). Hopefully this overview leaves you with a song made up of a couple of patterns. Refer to the on-board user manual for more detailed information on quantization, setting the tempo via tap tempo, exporting your song as an audio file, piano mode for triggering notes, and many other features. If you're like me, launching a new synth is like getting a new toy, and you may find yourself auditioning presets into the wee hours. So far we have analog and FM synthesis covered, which covers bass, chords, and leads (duties that can be shared with electric guitar). Our virtual band also has drums. But what about a really good piano? * I recently spotted a forum comment where someone complained that Ubuntu Studio does not lend itself to “just sitting down to play the piano”. While we're only using out-of-the-box, native Linux instruments, the best answer is probably to download a piano soundfont to use with Qsynth. But as noted previously, there is a trade-off between sound quality and the size of a sample. Linux compatible Pianoteq 6 starts at $130 and has a 50MB footprint. A smaller-sized, free piano sample may loop the fade-out of a note to minimize the soundfont's overall footprint. The bottom line is that it's often best to simply record a real instrument, such as a digital or stage piano. As for the commenter who just wants to play piano and doesn't want to deal with configuring software on his computer, it sounds like he should rescue an old acoustic piano and leave it at that! Your soundcard should be able to accept microphone input. So, if you have one, your ultimate “piano patch” might well be a real piano. But don't despair: once we learn how to run Windows-only VST plugins in chapter 5, you'll have your pick of pianos - see the appendix for some links. http://www.pianoteq.com – a native Linux piano. Audio Processors Ubuntu Studio comes with an insane number of effects and signal processors. I will only cover two guitar effects plugins here, and we'll see more about effects when we talk about recording. Guitarx is labeled as a “simple mono amplifier simulation”, but it is comparable to other amp models, with the ability to add rack units to your heart's content. I am not a guitar player, and have no stomp boxes or dedicated guitar amp. But even if you have a great live rig, plugins are just simpler to set up and use for digital recording. Are the eighteen different “Tube” settings are dead ringers for their namesakes? Does “Twin” really sounds just like a Fender Twin Reverb amp? Only you can decied, but t is very simple to go from a little crunch to a searing lead to a clean, slow tremolo. Click “Plugins/Plugin bar” and the entire gamut of effects is displayed. To add a rack unit from this selection, just double click. Throw the toggle switch on the left side of the unit to make it's LED light turn green, then adjust the knobs to your liking. To remove a rack unit, simply double-click one of the “screws” on its front panel. Skeuomorphic design – where one material, say plastic, is made to look like another, such as wood grain - has been around too long and there has been some criticism of it's use on virtual instruments. Yet the green brushed metal and chunky black knobs of guitarx make for a GUI that looks - and is - ready to rock. Set your sound card for monaural instrument input and make sure guitarx's output connects to System in JACK, then try the three banks of presets to get a feeling for guitarx's strengths. Rakarrak If you like to chain effects together as in a pedal board, Rakarrak is the plugin for you. I won't try to describe it's three banks of 60 presets each (plus a user bank!) other than to say Rakarrak is one of my favorite things to play around with in Ubuntu Studio. You can just park it on any preset and start fiddling with parameters to radically alter the sound. Once you load and connect it, click “FX On” so that it lights. The I/O faders default to 50-50, so you may want to adjust that balance to ensure the effect is all you hear. But first, set FX% to zero with FX On, and enable the Tuner in the top right-hand column. When you strike a note, the tuner displays it. As you work the tuning pegs on your guitar, the pitch meter will show fine tuning between sharp and flat. Even if you have another guitar tuner, this one proves very handy when recording on the computer. Rakarrak can turn your electric guitar into a MIDI controller. If you've ever wanted to play a guitar synthesizer, now you can control virtual instruments...with no extra gear!** Just below the Tuner, you'll see a MIDI section, something you might overlook while browsing presets, jamming, and cooking up your own blend of effects. Open one of the synths we've tried, such as amsynth, and enable MIDI in Rakarrak. You will see Rak' as an available MIDI source in JACK – just connect it to your synth plugin as any other controller, and – voila! - guitarists now have a whole new world of crazy sounds at their disposal. You may notice a bit of latency or delay between striking a string and hearing the note played back on the synth. The degree of this issue may vary from one sound or synth to the next. A quick fix to fill out your sound is to turn the Input fader back up a bit, as long as you don't mind layering the guitar sound with the synth patch you've chosen. Another problem is unwanted ghost notes. You can try adjusting the velocity and trigger settings in Rakarrak's MIDI section, but depending on what you're after, the stray notes can take on a surprisingly convincing arpeggiator character. In general, mono, lead sounds work well, and sounds like organ can take on a more mechanical sound when controlled from a fretboard. Linux musicians tend to be experimentalists, and to that end, I highly recommend trying Rakarrak's MIDI feature. Performance issues might be better or worse depending on your hardware, the plugin, and even the particular patch. Rakarrak set to one of the author's favorite presets. Tuner and MIDI sections are in the upper right. ToneLib GFX Ubuntu Studio has historically included a 30 day evaluation copy of ToneLib GFX, which has a straightforward pedalboard layout where you can click and drag thumbnails of effects boxes to add or reorder the chain to quickly craft the sound you want. As can happen with physical gear, there can be serious hum even when the guitar is not plugged in, and depending on your instrument, the hum can be beyond annoying. ToneLib GFX has a noise reducer that gets this problem under control. Tools & Utilities There are a few things to be aware of under the Audio Production “MIDI Utilities” and “Mixers and Card Control” menus but feel free to return to this section later and go to the next chapter if you are itching to start recording. The recording software we'll be focusing on has an excellent on-board mixer, and the standalone mixers available in Ubuntu Studio are for dedicated purposes or affect the onboard soundcard which we won't be using for recording. Note that Ubuntu Studio Audio Configuration is now the current place to adjust supported low-latency audio settings on modern Ubuntu Studio releases. There's even a level meter that might prove useful – or at least look cool – if you have a widescreen monitor with a corner of available desktop space. Major File Types Some common file extensions in Linux music software are LADSPA, LV2, DSSI, and SO. The following definition is via https://www.ladspa.org/ Linux Audio Developer’s Simple Plugin API, LADSPA, is a standard that allows software audio processors and effects to be plugged into a wide range of audio synthesis and recording packages. For instance, it allows a developer to write a reverb program and bundle it into a LADSPA "plugin library." Ordinary users can then use this reverb within any LADSPA-friendly audio application. Most major audio applications on Linux support LADSPA. And via http://lv2plug.in/ LV2 is the “version 2” of LADSPA. Unlike many popular audio plugin APIs, LV2 is a platform-agnostic Free Software specification with a liberal license. Via http://dssi.sourceforge.net/ DSSI (pronounced "dizzy") is an API for audio processing plugins, particularly useful for software synthesis plugins with user interfaces. DSSI is an open and well-documented specification developed for use in Linux audio applications, although portable to other platforms. SO files are shared objects, and are not restricted to audio application. They are the equivalent of dll files in Windows. You'll notice another acronym in these definitions – as any developers out there will know, an API is an Application Programming Interface. Remember, Ubuntu is open source, which means you have access to the code (often written in C or C++). The above open standards mean developers can create their own audio plugins, be they effects or synthesizers or whatever they've dreamed up. The ability to download and modify code has led to an explosion of innovative, colorful plugins. There is some redundancy, but if you look closely, you'll see all of the major schools of synthesizer design have been replicated, and some fascinating hybrids designs as well (see the glossary in section 10). Tools for DJs In the Audio Production menu, you'll notice some tools explicitly for the DJ. Internet DJ Console allows you to live stream over the internet. I have not tried this program myself, but it is geared towards podcasting. I did attempt to use SuperLooper, and once you figure out the labyrinthine interface, it does work as promised. You can create as many overlapping loops as you like. Sessions can be saved and imported to other programs. While intended for live performance, this plugin is not restricted for DJs – if you like overdubbing on the fly, it has great musical applications, and loops in themselves can be quite useful. Some documentation for SuperLooper can be found here: http://essej.net/sooperlooper/.<
> Note: SuperLooper is not included in the Ubuntu repositories and is therefore not officially supported. TerminatorX is an intriguing program (not bundled with Ubuntu Studio) that simulates record scratching using a digital track and a mouse. The mouse isn't the most comfortable tool for the deft handiwork exhibited by true practitioners, so in the spirit of open source, some fans of this plugin have repurposed old turntables, fitting them with a mouse to reproduce the visual and tactile experience of scratching an actual vinyl LP! https://terminatorx.org/turntables/ *

Sharing Your Music

It's remarkable how many creative people know little to nothing about intellectual property. That's why, even in a book about open source shareware, it's important to discuss.

Creative Commons

Unless you have a million dollar marketing campaign behind you, you're probably going to want to just post your music to a blog or some streaming sites and be done with it. Downloads don't make up a very large percentage of revenue, even for most established acts. And physical recordings, while nice to have at gigs, are considered a loss leader by many. Can't someone just rip your CD and file share it? Still, you might want to take some basic steps towards controlling how your music gets used. With a Creative Commons license, you can, at the very least, clearly express your intent - for example, a song might be in the public domain for personal, non-commercial use, but you retain rights in the song if someone wants to use it for a TV commercial. Just go to the web site, fill out a very short form and you will get a link and code you can embed that shows at a glance how the song can be used, including permission to create derivative material and whether the work should be attributed to you. Creative Commons is a reaction to what some feel are overly-restrictive copyright rules, extended by the 1998 Sonny Bono Copyright Act to 70 years after the holder dies. The whole point is to allow artists to expand the public domain without putting themselves in a position with no recourse should someone else commercialize their work. I believe this fits well with the ethos behind open source software. There is an example of a CC license in the frontispiece of this book.

https://creativecommons.org/choose/

Copyright Registration

The next step up from Creative Commons is to register your music for copyright with the Library Of Congress. If you read their FAQ (link is below), you'll see that as soon as a creative work is put down in a "fixed medium", you own the copyright. From there, it's a matter of building up evidence that you created the work - this can include performing the piece, and of course the registration counts (mailing your song to yourself does not hold up in a court of law). The price for online registration is $35 per song (not work made for hire, and you are the only author), so you might want to consider how many registration forms you want to submit.

https://www.copyright.gov/help/faq/faq-register.html

Royalty Collection Agencies

Publishers get half of the royalties for songs they sell on their client's behalf. This is why most professional songwriters establish themselves as publishers! The problem is, as individuals, we don't have the same connections and distribution capabilities as a true publishing operation, and should you be so lucky as to get a deal, that will almost certainly involve giving up the publishing, at least for some period of time. Some artists are hoping the blockchain method of payment and distribution cuts out the middleman and can help enforce CC-like licenses. Still, you might want to join ASCAP or BMI to list your original music with them, in case there are ever royalties to collect. Your membership could also prove useful in getting paid on collaborations and other projects. There is a lot more to the subject of intellectual property and business models in the internet age. It should go without saying that you should consult an entertainment lawyer before signing anything.

Making a CD

Despite the decline of the need for physical discs, surprisingly many people cannot deal with MP3 or other digital formats and prefer old school audio CDs. It's also good to have CDs at gigs. The simplest way to make a few CDs is to burn copies on your computer and bust out the Sharpie pen. Under the main menu in Ubuntu Studio, navigate to Media Playback/Brasero to find a no-frills CD burner. You can just drag your wav files into Brasero's file list. Click and drag .wav files to change the playing order. Click individual files to set the properties such as Title and Artist. When the song list looks good, if you have not already done so, insert a blank CD, and be sure to select it as the destination. Press the "Burn" button - accept or edit the default settings on the subsequent pop-up, and presto - the CD will write. You can elect to make more than one copy, but definitely check the first copy before inserting more discs.

As for that Sharpie pen, there are a couple of options to make better-looking CDs. One is to get Avery CD labels. There is a PDF template that will help you line up your artwork so you can print these sticky-backed labels on your home printer. Ubuntu Studio comes with Gimp image editor pre-installed, and Gimp can edit and save the PDF template. Adhesive labels fell out of favor some time ago for getting stuck in some CD trays. If you go this route, use a label pressing device to assure the label goes on evenly with no creases or bubbles.

There are dedicated CD printers that use special blank media, but such printers are costly. Having your CD professionally printed in small lots turns out to be relatively affordable and the end result will look terrific. They will also provide a handy template that provides a printable preview, if you want to make the cover yourself. You can easily find graphic designers to do this online. If you are having CDs made up for a gig or special occasion, be sure to allow ample time for production, mailing, etc.

I will assume you are already familiar with the many streaming sites where you can post your music for downloading. For podcasts, don't forget the Internet DJ Console (screenshot in chapter 3).

Sheet Music With MuseScore

Of course you can make ditigal music without ever touching an instrument. Platforms like Ubuntu Studio have democratized music and let's face it - learning to play an instrument well takes dedication. But musical notation, evolved over hundreds of years, is how we communicate ideas with other musicians. The beautiful clef signs, brackets, and rests no doubt took their form in part because they lend themselves to the quill pen. No discussion on sharing your music would be complete without mentioning MuseScore, which can produce very complex music charts entered by hand or imported MIDI file - no quill pen required. I will leave you with a screenshot of a user-submitted file and refer you to the online manual (see Help) for further information.

Musescore's notation is both comprehensive and elegant.

Sound Synthesis 101

By now you have seen quite a few virtual synthesizers with a bewildering array of GUIs. In this section, we will try to see what they all have in common with the goal of being able to modify and create patches.

In the most general terms, a synthesizer is an electronic instrument that sends one or more pure waveforms through a pipeline of filters and other processors to modify and mangle that waveform. The classic starting points are the sine, the square, the sawtooth, and noise. Pulse and triangle are also fairly common. Some hybrid waveforms are not unusual, and as we saw in Zebralette, some instruments let you draw and stack waves to produce very rich sounds. These geometric names are derived from how the sounds appear on an oscilloscope, which shows voltage over time, allowing analysis of things like frequency and amplitude of a signal. The pure tone is a single frequency sine wave (note that the other wave shapes can be constructed from sine and cosine waves). In theory, by crafting sounds the right way, it should be possible to recreate sounds of real instruments and nature. In practice, with a few exceptions, analog synthesizers can only approximate "real" instruments. Highly convincing, realistic patches were brought about in the 1980's by sampling synthesizers, which could be argued as cheating, since a sample, as we've seen, is just a little digital recording (and having a precise clarinet sound only showed how the keyboard could not convey all the subtleties of the human mouth tooting on a slobbery reed). In any case, it helps to listen to the unmodified waveforms to get a feeling for the starting point - many plugins have a plain vanilla initial patch that is a pure tone. A sine wave sounds like whistling or blowing across the top of a bottle, a sawtooth wave sounds a bit like it looks - like a buzzer. White noise is static and can be used for sound effects like wind or ocean waves and percussion sounds.

The short explanation for a 1970's analog synth's inability to recreate natural sounds is that those sounds are composed of many overlapping waves, not just one or two. The long answer involves complex Fourier analysis of sound waves. But synthesizers opened up a whole new world of strange and novel sounds that gave birth to electronic music as we know it today (with proper credit to early studio pioneers who were happily making what can only be called electronic music well before the invention of the modular synthesizer).

The timbre of a patch is comprised of its spectra (those waveforms) and its envelope (fast or slow attack, ringing or abrupt ending (decay), etc - drum hit versus a bell versus a slow violin crescendo). So creating your own sound is just a question of figuring out how to mess around with those two elements of timbre on any given synthesizer. A perfectly valid approach to this is to stop here, and just start "knob twisting" at random, hitting "save" when you get a pleasing result. You will soon learn what "LFO" does, even if you don't know that it means "Low Frequency Oscillator" - and after all, does knowing what the initials stand for help much?

Here are ten quick ways to modify the basic waveforms on any synthesizer. These won't make you an expert sound designer, but hopefully will de-mystify all those crazy knobs and initials. Not every synth has all of these capabilities.

Knob acronyms VCO

• voltage controlled oscillator: created the raw waveform, so this is our starting point.

LFO

• low frequency oscillator: add tremolo or vibrato.

VCF

• voltage controlled filter: add sweeping wah effects.

VCA

• voltage controlled amplifier: gain (note - this is probably post-ADSR section)

HPF

• high pass filter: knocks out low frequencies

Ten things to try on any synthesizer

1. Go straight to the cutoff filter or VCF to smooth out the sound. This is kind of skipping some steps, but it's one of the most noticeable things you can do to affect the sound on any synth. You'll notice that slowly modifying the cutoff frequency makes the classic "sweep" sound, and it should be possible to use another control, such as the LFO, to automate that sweeping as the note is held down. Early modular synthesizers allowed you to connect anything to anything and see what happens. In the same spirit, most plugins have a way to route a controlling signal from here to an oscillator over there. Take a moment to look at the panel and break down the various sections and the signal flow.
2. The most understandable and quickest way to modify a sound is to play with the envelope, which will be labeled "ADSR" for "Attack, Decay, Sustain, Release". Let's say you pluck a guitar string. The attack is the ramp up, which is pretty abrupt, the decay is the other side of that initial pluck - the time it takes to reach the sustain time (the remaining time the note remains level). The release is what happens when you let go (or lift your finger from the key). In the case of a real guitar, the sustain would be about three or four seconds and the release would be around zero. It's fun to give a sound a very long release so you can just tap a key and listen to it slowly fade. Some sounds lend themselves to a gradual attack, although if it's too slow, it may feel out of tempo in the context of a particular recording. Smaller changes to the attack come closer to emulating real-world differences which are in the millisecond range. A snare hit is instantaneous, a tuba or french horn is less precise, and the sound of a gong may peak well after it is struck. Organ notes play at one volume and stop the second you release the key. All of these aspects to sound are governed by the ADSR section, and changes to the sound from the other sections generally happen over time, so the ADSR is indirectly affecting those, too. Note that some plugins will also have a "hold" (H) parameter that may be used to set a fixed duration for sustain or the full volume of the attack, ans have "ADSHR" or "AHDSR" sections.
3. Try creating a cymbal crash by using only white noise, then tweaking the ADSR. What happens when you make that cymbal a very short blip?
4. Another instant alteration of a waveform is ring modulation, if it's available. This gives a harsh bite to your sound, almost the equivalent of adding overdrive and a little distortion to an electric guitar (those sorts of patches very likely use ring mod or resonance). Usually you only need to enable it, but try tweaking it to be more or less subtle.
5. Just jumping the octave can alter a patch in unexpected ways. Does that "Killer Bass" also work as a lead patch when played in a higher register? What if you knock it upstairs then tweak the envelope a little? Many synths have a button to transpose an octave at a time (and another way to change properties of a note, including pitch).
6. Try the LFO to chop up a sound or add wobble to a sound.
7. Portamento, anyone? This is another parameter where a little goes a long way. Overdo it and you're left with a cartoony slide whistle that is only any good for a special effect. But adding just a touch can juice up a lead sound nicely. You'll notice a fair number of presets use it that way.
8. If there is an effects panel, slapping on some delay can high a high impact. Put another way, I have noticed removing the delay from certain rompler (sample-based plugin) patches (I won't name names) reveals the underlying sound to be less than inspiring. Re-enable the delay and it's ready to go to Mars.
9. Many synths have multiple oscillators. A quick way to get a more sophisticated sound is to detune one or more waves just a tiny bit. So look out for a knob that says "detune". That is a quick way to get a fat, hovering sound.
10. One last section that is not on nearly enough synthesizers is the arpeggiator. This will automatically play notes you hold down, and often you can choose in what sequence - up and down, only up, only down, random, or in the order in which you play them. This classic synth trick can be the basis for a whole song!

So far, this discussion has focused on analog synths because a lot of free VSTs are analog emulators. There are many different approaches to sound synthesis, and the description for each plugin will say which type of synthesis it is are using. Some instruments purposely take a radically different approach to either the interface or to sound generation or both. For me, the more quirky and experimental, the better. But occasionally, a plugin is just impenetrable. In that case, just go with the presets or move on. You should not have to battle a synth just to tweak a patch. On the other hand, it is only fair to read the manual. I mostly stick with presets, but still feel a passing familiarity with the history of how synthesizers have evolved, the lingo, and the capabilities is important - a short list of resources appears in the appendix. Go forth and knob-twist!

Approaches to Sound Synthesis

Here are very brief descriptions of some of the major types of synthesizers that you will see recreated as plugins. Between other methods not mentioned and hybrids, this is just scratching the surface.

Subtractive

• Applies filters to complex waveforms. Can employ Pulse Width Modulation, which sounds like a chorus or detuning effect.

Formant

• A subset of the subtractive approach that pays attention to the formant or characteristic frequency peaks associated with the resonant cavity of the instrument being modeled.

Modular

• Early 1960's synthesizers such as the Moog and Buchla were massive component racks; individual components were connected by patch cords. These analog synthesizers were bulky and expensive. In recent years, there has been a resurgence of interest in modular synthesis, and there are emulators that let you draw a "cable" between inputs. It's still expensive to build a "eurorack", so a plugin is a great way to test the waters, if you aren't sure it's for you.

Additive

• Adding waveforms results in more harmonic overtones - the components of natural sounds mentioned before.

Frequency Modulation (FM)

• Through multiple oscillators and a more graduated voltage control scheme, digital synthesizers like the Yamaha DX7 (1983-1989) offered sophisticated sounds at an affordable price.

Wavetable

• Uses random waveforms as the tone generator.

Phase distortion

• Starts with more complex digital waveforms In the Casio CZ series, which also emerged in the 80's, the digital filtering and amplification also went through an eight stage envelope, allowing for sounds that evolved over time more than could be achieved with the usual ADSR.

Physical modeling

• Ever greater processing power allowed for mathematically modeling not only the detailed harmonics of an instrument, but other parameters such as the resonance of the body.

Sampling

• As we've seen, samplers are digital recordings of individual notes that can be played back at different pitches. ROMplers are plugins that rely on sample presets - both keyboards and plugins can apply additional filters and effects to samples, layer them, etc.

Granular

• A sample is chopped into millisecond bits which can then be layered, played back at different speeds, and processed.

Patch Tutorials - Funk Bass

Let's apply some of the above ideas to make a simple funky bass, a classic analog synth sound. This need not be polyphonic, and it will have a very short, almost clipped envelope. It needs to be thick and needs to go "BOW-BOW-BOW", which effect will be achieved with a filter. We'll use the highly-rated Synth1, modeled after the Nord Lead Red. Download it to your VST directory from here (note 32 bit versions often work better than 64 bit):

http://www.vst4free.com/free_vst.php?plugin=Synth1&id=245

Start Synth1

1. Open the terminal window and change directory to where you installed Carla, for example: $ cd /usr/local/share/Carla
2. Launch Carla: /usr/local/share/carla$ Carla
3. In Carla's window, click the green '+' sign (Add Plugin), and select Synth1.
4. Click the gear icon on the Synth1 rack unit. You should see the GUI.
5. At the bottom of the GUI, click soundbank. A popup window will appear. Select the "All" dropdown menu and navigate to 01:soundbank01(0) - this is a completely empty soundbank.
6. Load the first sound by selecting it, then close the soundbank window.
7. Now set the parameters to match the following screenshot.

Notes on the Funk Bass setup:

1. In the far right panel, disable any effects by clicking the "ON" button until it goes gray.
2. To get the clipped envelope we're after, turn everything down on the ADSR control but the decay.
3. Choose the sine wave for oscillator 1.
4. Now just tweak the filter settings in the middle of Synth1's middle panel until you get somehting you like. For more wah, open the attack filter.
5. You can go back to Oscillator 1 and try different waveforms. Recall that sawtooth has more "bite"? Now you can hear that for yourself. Play with other parameters one at a time to see what effect they have on your patch.
6. If you like this patch, use the dark red "write" button at the middle bottom of the GUI. A popup will let you name the patch and save it to the empty bank for your next session.

Arpeggiator

To try out tip #10 above, download Poly 2106, a well-executed Juno 106 emulator, from here: http://www.vst4free.com/free_vst.php?plugin=Poly_2106&id=1329

This plugin has very clearly marked "Arpegiator [sic] Gate" section at bottom right. Just click the "OFF" button so it changes to "ON" and turns red. Then play around with the controls in that section. Note that "HOLD" will keep the pattern playing even after you release the keys. Experiment with the other controls to vary the tempo and direction of the arpeggio. TR-GT mode lets you space chordal hits on a timeline, and they can be more or less legato.

Crafting Noise

Install TAL-Noisemaker from here: https://tal-software.com/products/tal-noisemaker

The following setup modifies a noise signal. The envelope is set something like a crash cymbal, but instead of a static filter setting, LFO1 and LFO2 are controlling the filter. Adjust the rate on the LFOs to your liking, or click the dropdown that says "Filter" to disable them. Note that Master/Sub is turned all the way down.

Disabling LFO1 and 2, slightly raising the Cutoff and Resonance, and shortening the envelope turns our wavy crash cymbal into something more akin to a hand-clap.

And what discussion of noise patches would be complete without the Helicopter sound effect? This one fades into the distance when you release the key.

*Minor modifications to the envelope and other controls can change plain noise into different percussion sounds or sound effects. *

Siren

Here is an example of controlling the pitch of an oscillator with the LFO. Install Pure Pone from here: http://www.vst4free.com/free_vst.php?plugin=Pure-Pone&id=877

Certainly not the most musical setting, but a good demonstration of how to modify a parameter from another parameter, the essence of synthesizer programming.

1. Call up the patch called Analog 6 (because it is a relatively plain vanilla patch).
2. Turn off Modulation Bus 2, we don't need it.
3. Set Modulation Bus 1 source to LFO, it's destination to OSZ1-3, and the amount to MOUNT.
4. Crank up the Amount to about 6.
5. I set the LFO to use a Sine wave and the rate of this oscillator to about 3.
6. After playing around with the Oscillators, it sounds best with OSZ1 turned off, so toggle that switch.
7. Set the waveform for OSZ2 to triangle a sawtooth and octave to 0.
8. Set the waveform for OSZ3 to the triangle in the opposite direction of OSZ2's, and octave to 1.
9. Make sure any effects are disabled.

You should hear a slow rising and falling pitch.

• • To make it go faster, increase the LFO frequency. • To make it see-saw like a European police siren, change the LFO waveform to a square wave. • To change the pitch range, adjust Mod Bus 1's Amount. • Hear what happens to the timbre as you modify the waveforms of OSZ2 and 3.

I had a little trouble finding a plugin where it was simple to make the Siren patch, but I hope these examples were enough to illustrate that there is a lot in common from one plugin to the next in editing and creating patches. One or more sources (oscillators) is modified by various signal processors and effects, some of which may themselves be waves, some will be filters. Once the wave is shaped, it goes through the ADSR envelope, the the master volume control. Usually, these controls are in some kind of sectional arrangement. It just becomes a question of figuring out how to assign them. With a little practice, you will be able to imagine a sound and have a rough idea of how to build that patch from scratch. While there is nothing wrong with using presets, as you can see, a tiny twist of a single knob can dramatically alter what you get from a given patch. Presets are intended to demonstrate the capabilities of a plugin, so don't be afraid to mess around with the controls. Any synth developer would tell you "that's what they're there for!"

The opening preset of Osiris-6, "Delay Pad" is a perfect example of a sweep effect with a slow attack.

Osiris packs a lot of sound editing capability into a relatively easy-to-follow layout. Two oscillators are on the left. The yellow buttons rotate through all available options. You can pick filter 1, 2, or both. And the panel outline suggests that the filters have their own ADSR, which is above the ADSR for the gain. To the left of the keyboard is the mono on/off and portamento control. Tucked to the right of the keyboard is the arpeggiator. Effects are front and center. It is very easy to page through the options for LFO1 and LFO2 as you listen to how the sound is affected in real time. This is truly one of the best designed front panel layouts. Osiris shines in the pad department, but the cutoff and resonance knobs do not seem to alter those sorts of sounds much. One drawback of this plugin is that it appears to take up a lot of memory - it failed to load four times on my old laptop. Download it here: http://www.vst4free.com/free_vst.php?plugin=Osiris-6&id=741

Using VST Plugins

Virtual Studio Technology (VST) is a standard for software synthesizer and effect plugins invented by Steinberg (maker of the Cubase DAW).

To get started, here is a remarkable and very popular free synth from German vendor U-He: https://u-he.com/products/zebralette/

Download the Linux version and unzip it to your ~/.vst directory. If the ~/.vst directory doesn't exist, you can create it.

One of the programs that can be used to run and manage VSTs is Carla. Here's how to get it:

Install and Run Carla

Carla is available in current Ubuntu Studio releases.

Configuring and Using Carla

On the far right of Carla's top menu, click "Configure Carla" to see the Settings pop-up window. Go to "Paths" and make sure "VST" is selected in the dropdown at the top center of the Settings pop-up. Add the full path to the directory you created earlier, unless it's there by default. It might look something like this: ~/.vst

Also check the project path under Carla's "Main" tab. Click "OK" to save your changes and dismiss this window. Finally, click the "+ Add plugin" button, and click "Refresh" on the subsequent pop-up window. Carla will search for Zebralette and any other VST plugins you've installed under the VST path. These may take a while to load, during which time it will look like Carla isn't doing anything. If you get an error message, loading may have simply timed out - try it again a few times. When the plugin becomes available, it will also show up in JACK, where you can connect it to System and your MIDI controller. Check that everything works. Back in Carla, you can see the GUI for this and other VSTs by clicking the gear icon (white gear at top left the following screenshot).

Zebralette and other free VSTs may have been released a few years ago, but that doesn't mean you can't make fresh-sounding music with them. Always check out commercial offerings and/or consider a donation to the developer if you end up making heavy use of a particular plugin. Most have a PayPal tip jar. Carla's wrench icon is important because it allows you to bind synth parameters like filters or the VCA rate to knobs on your controller, such as the modulation wheel. Just find the Continuous Controller number for a given knob, and set that as the CC# for a given parameter in the wrench's pop-up window. Your controller's manual will show the CC assignments. In the following example, the modulation wheel is CC# 1, and is being used to control the Hi-cut Frequency (circled in red).

Zebralette's rich and varied sounds come from the ability to stack and draw custom waveforms. The Presets tab on this "morphing" synth is the third tab from the left on the bottom tier.

Any parameter can be bound to a given CC number. Multiple parameters cannot be assigned to the same CC number. Settings can be stored and recalled.

It's not difficult to find free VSTs, but here are two sites that have hundreds, if not thousands of free plugins: http://vst4free.com which sorts by name, rating, and last added (in addition to giving a random list when you first roll up on the site) and http://vstplanet.com. Note that not all freeware uses legally-obtained samples. Additional reviews of some VST plugins appear in the appendix.

Do know that many VSTs are built for Windows, which requires the WINE Windows emulator and a plugin bridge. A part for that process may be added to this section at a later date. Be sure to use the latest version of WINE.

Audio User Guide for Ubuntu Studio

Here's a short introduction to audio on Ubuntu Studio. Current releases use PipeWire for desktop audio with JACK compatibility, plus Ubuntu Studio Audio Configuration for low-latency audio setup.

PipeWire - The Desktop Sound System

What is PipeWire?

PipeWire is the default sound system on Ubuntu Studio, and handles all desktop sound. It uses ALSA as its backend, meaning ALSA provides the drivers for your soundcard.

Controlling PipeWire is done mainly from the desktop audio controls. But, for some cards, not everything can be adjusted from there and you will need to use alsamixer or a special mixer (mentioned below) to get further control of your audio device.

Supported Devices

ALSA provides driver support

Any device that is supported by ALSA is potentially supported by PipeWire. PipeWire provides JACK compatibility, so multichannel pro audio cards that work with ALSA can usually be used directly in current Ubuntu Studio releases.

FireWire will only work with special configuration

FireWire devices can still require FFADO-based support depending on the hardware. PipeWire handles desktop audio, while JACK-compatible applications should be connected through the current audio stack rather than a legacy bridge.

No Volume?

Many cards are muted by default, and need to be accessed with a special mixer in order to be controlled. There is a generic alsa mixer in the main menu at **menu -> Audio Production -> Mixers -> Mixer **. To use it, you will first need to select the card you wish to control, and make its controls visible from Select Controls. If I for example want to raise volumes for a m-audio delta device, I will first need to make all the ADCs (Audio to Digital Converter) and DACs (Digital to Audio converter) visible to control the volume for inputs and outputs.

PCI mixers

There are also card specific mixers. They are not actually "brand" specific, but "chip" specific, so some mixers will work with many brands that share the same internal chip. These mixers are useful for controlling your device directly through ALSA, and they remain useful alongside PipeWire and JACK-compatible applications.

To find out which chip your pci audio device has, look up the brand here. Select it, and try to find the chipset for your model. One particularly common chipset is the envy24(ice1712).

Here's a list of mixers for pci devices that are preinstalled with Ubuntu Studio (comes with the alsa-tools package):

echomixer is the Linux equivalent of the Echoaudio console application from Echoaudio. It is a tool to control all the features of any Echoaudio soundcard. This includes clock sources, input and output gains, mixers, etc.

hdspmixer is the Linux equivalent of the Totalmix application from RME. It is a tool to control the advanced routing features of the RME Hammerfall DSP soundcard series. To handle RME Hammerfall cards you might also need the tools hdspconf and hdsploader

mudita24 - is a control tool for Envy24 (ice1712) based sound cards, and replaces the older envy24control (M-Audio Delta Series)

rmedigicontrol - is a control tool for RME Digi32 and RME Digi96 sound cards. It provides a graphical frontend for all the sound card controls and switches.

More Information

More information on supported hardware can be found here.

JACK - The Pro Audio Sound System

JACK is a sound server, and like PipeWire it can work with ALSA as its backend. JACK is also able to use other drivers, such as the FireWire driver developed by FFADO. Commonly, those are the only two drivers used with JACK for audio devices on a Linux machine.

Why use JACK?

Many audio applications will only work with JACK - Applications meant for pro audio use will often work best with JACK.

JACK is extremely low latency capable - JACK is able to give you extremely low latencies at the right conditions. Which is a must if you are to play a live software instrument.

Some devices will only work with JACK - As mentioned above, FireWire devices may still require extra configuration.

JACK connectability - When using JACK you can connect any application to any other application just as if you were using physical cables. You are thus not restricted by the functionality of a single application.

Starting JACK

The easiest way to configure JACK-compatible audio on current Ubuntu Studio releases is to use Ubuntu Studio Audio Configuration. To learn more, see Ubuntu Studio Audio Configuration.

FireWire Troubleshooting

Sometimes it's just a matter of knowing what to do in which order. Maybe you need to start your computer with the FireWire device already attached, or the other way around. Try different combinations, if you are sure the device is supported. (more info on supported devices here).

USB troubleshooting

A common thing to try is to adjust the latency or quantum settings in Ubuntu Studio Audio Configuration, or use a JACK period setting of 3 when running native JACK with compatible USB hardware.

Reducing Xruns

Xruns are either a buffer overflow or buffer underflow of the audio system in JACK. These can be heard as a popping or a ticking sound. Reducing or eliminating Xruns can be done with multiple methods, such as:

• Turning off and using a wired network connection
• Turning off bluetooth
• Disabling unnecessary audio bridges or compatibility layers
• Reduce background processes

If none of these methods work, the only way to reduce or eliminate Xruns is to raise your buffer to a higher setting.

Audio User Guide for Ubuntu Studio

Here's a short introduction to audio on Ubuntu Studio. Shortly about what audio systems we have, and how to make use of them.

Pulseaudio - The Desktop Sound System

What is pulseaudio?

Pulseaudio is the default sound system on Ubuntu Studio, and handles all desktop sound. It uses alsa as its backend, meaning alsa provides the drivers for your soundcard.

Controlling pulseaudio is done mainly from the volume control in the indicator area. But, for some cards, not everything can be adjusted from there and you will need to use the generic alsamixer or a special mixer (mentioned below) to get further control of your audio device.

Supported Devices

Alsa provides driver support

Any device that is supported by alsa is potentially supported by Pulseaudio. Usually only pro audio multichannel cards may have problems with pulseaudio. If you find that your multichannel card is not working with pulseaudio, but is supported by alsa, it will still work perfectly with jack. To get desktop audio working for such a card, you will need to set up the pulseaudio to jack bridge mentioned below.

Firewire will only work with special configuration

Currently, firewire devices are not supported by alsa, and may only be used with jack using the ffado firewire driver. But, since we are now able to connect Pulseaudio to jack, using the pulseaudio to jack bridge, we can circumvent this problem.

No Volume?

Many cards are muted by default, and need to be accessed with a special mixer in order to be controlled. There is a generic alsa mixer in the main menu at **menu -> Audio Production -> Mixers -> Mixer **. To use it, you will first need to select the card you wish to control, and make its controls visible from Select Controls. If I for example want to raise volumes for a m-audio delta device, I will first need to make all the ADCs (Audio to Digital Converter) and DACs (Digital to Audio converter) visible to control the volume for inputs and outputs.

Pci mixers

There are also card specific mixers. They are not actually "brand" specific, but "chip" specific, so some mixers will work with many brands that share the same internal chip. These mixers are not only needed to control your device with pulseaudio, but also with jack, since both use alsa as its' backend.

To find out which chip your pci audio device has, look up the brand here. Select it, and try to find the chipset for your model. One particularly common chipset is the envy24(ice1712).

Here's a list of mixers for pci devices that are preinstalled with Ubuntu Studio (comes with the alsa-tools package):

You are thus not restricted by the functionality of a single application. You can even route pulseaudio to jack, and make use of all of it's desktop audio capability.

Starting Jack

The easiest way to start jack is to use Ubuntu Studio Controls. To learn more, a guide to Ubuntu Studio Controls can be found here.

UbuntuStudio/ProAudioIntro/UbuntuStudioControls

Ubuntu Studio Controls

This subpage is retained only as a legacy alias.

Current Ubuntu Studio releases use Ubuntu Studio Audio Configuration instead.

UbuntuStudio/UbuntuStudioControls - Community Help Wiki

Ubuntu Studio Controls is a legacy tool. Current Ubuntu Studio releases use Ubuntu Studio Audio Configuration as the primary interface for configuring low-latency audio behavior, PipeWire quantum, PipeWire-JACK, and kernel low-latency settings.

Current guidance

• For Ubuntu Studio 24.04 LTS and later, use the Ubuntu Studio Audio Configuration utility.
• For Ubuntu Studio 24.10 and later, the old PulseAudio/JACK switching workflow is no longer available.
• The legacy Studio Controls-based PulseAudio/JACK method is deprecated, not recommended, and unsupported.

Current documentation lives on ubuntustudio.org:

• Ubuntu Studio Audio Configuration
• Ubuntu Studio Installer

Historical note

Ubuntu Studio Controls used to handle tasks such as JACK startup, audio bridging, CPU governor tuning, and low-latency setup on older Ubuntu Studio releases. Development has effectively stopped, and current Ubuntu Studio documentation treats it as legacy behavior kept only for older installations that still depend on it.

If you are maintaining an older system that still uses Ubuntu Studio Controls, treat this page as archival rather than current setup guidance.

Introduction To Computer Aided Graphics

In computing, Graphics is a broad term used to invoke many things related to the visual feedback of a computer. In this guide we will use the term Graphics to describe CAD (Computer Aided Design) and Photography. One could argue that video would fit into this guide. But given the complex nature of Computer Aided Video, it has it's own workflow explained in detail here.

The Realms Of Graphic Design

When we refer to graphic design executed with a computer, we have to understand the realms in which it operates and the distinctions between these realms. The main two realms we are going to focus on here are Prints and Digital Displays. It is important to understand these differences due to the way colors and shapes are generated to fit within these realms, and to be able to convert one realm to the other and vice versa. Even if both of these realms are (generally speaking) displayed in Two dimensions, they respectively include the notion of Three dimensional graphics (discussed later on in this article)

Resolution & Color On Digital Display

Because a computer screen uses light to display colors (as opposed to pigments in print), in this realm we generally talk about the 3 Aditive Primary Colors: Red, Blue and Green. Often shortened with RGB.

The resolution of a Digital Display is defined by the amount of pixels that can fit on the screen. There are two major ways in which shapes and colors are rendered on a computer monitor: using raster graphics (pixels), and using vector graphic. Due to their nature, raster graphics are resolution dependent, meaning they cannot scale up to an arbitrary resolution without loss of apparent quality. This property contrasts with the capabilities of vector graphics, which easily scale up to the quality of the device rendering them.

Resolution & Color In Prints

Becuase prints use pigments to display colors, in this realm we generally talk about Subtractive Primary Colors: Cyan, Magenta, Yellow and Black. Often shortened CMYK

Some sections may just contain a list of links. It is sometimes useful to include a short explanation of what the links are for. For example: 'Ubuntu includes the following Internet applications by default.'

• - Lists of links should have bullets. Link text should not be in bold. Each link should be followed by a short explanation of the link.
• - Explanations of links should be written as full sentences.

See Also

A see also section can be used to point users towards other trusted Ubuntu resources. For example, if a page exists in the official documentation on http://help.ubuntu.com, you can link to such a page. This section is optional.

• - Explanation of link.
• - Explanation of link.
• - Explanation of link.

External Links

An external links section can be used to point users towards general information about the subject matter of the page, such as a wikipedia entry or project homepage. This section is optional.

WikiGuide/Communication - Community Help Wiki

Introduction

Good communication with other wiki contributors is essential to writing great resources. Some guidelines:

General Communication

• IRC - #ubuntu-doc on irc.libera.chat
• Mailing lists - ubuntu-doc
• Comments - When saving your edits, always leave a comment so others can easily see what you did.

Page Categories and Linking

• Review - Tag your pages when they have not been reviewed, and discuss your contributions on the docteam mailing list. If you let us know about it, it can be reviewed more quickly and its tags removed.
• Do not add a link to an unreviewed page on the wiki's index pages (eg. UserDocumentation or Multimedia) until the page has been reviewed and is not tagged.

Subscribing to Pages

• Subscribe to the pages you have contributed to. To do this, click on the Subscribe link of the page you wish to subscribe to.

WikiGuide/DeletingAndRenaming - Community Help Wiki

• Do not delete or rename pages unless you really know what you're doing.

Users do not have permission on this wiki to delete or rename pages. Doing so can sometimes cause accidental, yet major, problems. This includes, but is not limited to, breaking links within the wiki itself and on the internet, as well as people's bookmarks.

For this reason, deleting and renaming pages on this wiki is restricted to the EditorGroup

If you do need to delete or rename a page, label it with the appropriate Tag.

However, before you do so, here are some things to think about:

1. A good alternative to renaming is to insert a redirect from the target page to the original page. See HelpOnProcessingInstructions.
2. You can search for all of the pages containing a link to a specific page by clicking on the title of the page. If you rename or delete a page, you MUST fix all these links.
3. If you are thinking about renaming a well-known or useful page, please discuss it on the DocumentationTeam mailing list first.

WikiGuide/Formatting - Community Help Wiki

The Ubuntu Community Help Wiki can often seem like a daunting thing to start editing, but this is in fact NOT the case! It is easy to start editing and improving the information recorded here. The best way to start is to look at the formatting which is employed on various pages. You can see the code of a page by logging in and selecting "Raw Text" from the 'More Actions:' drop down menu on the page.

The basics

• Paragraphs should be separated by a blank line.
• To make a list, use a white space at the beginning of a line, followed by either an asterisk (for bullet points), a number, letter etc.
• To make a heading, place one or more equality operators (=) at the beginning and end of a line.
  • Use just one on each side to set the page title, as in (= Title =),
  • Use a pair of them (== Heading ==) for major headings identifying large sections of text,
  • Use three for minor headings that focus on a single topic (=== Section ===), and so on.
• Placing '' around portions of text causes the text enclosed by them to be rendered as italic, whereas surrounding text with ''' will make the enclosed text render in boldface. They can be use in tandem, too, with groupings of five (5) generating text that is both boldface and italic.
• To quote a block of code, enclose it in {{{ }}}.

An example page might look like this:

= Page Title =

== First major subheading ==

This page is going to explain how to write a guide on the wiki. The following things are important:

 * Read the [[DocumentationTeam|Ubuntu Documentation Team]] [[DocumentationTeam/StyleGuide|Style Guide]]

 * Make sure you are not reproducing material already on the wiki

 * Ask the DocumentationTeam to check the guide afterwards and tag it appropriately

The following paragraph is a ordered list using lowercase letters as list markers:

 a. this is the ''first'' item

 a. this is the ''second'' item

 a. this is the ''third'' item

{{{

This is a block of code

} }} (the space should not be in your version)

It is that easy! For more documentation about this wiki, see the HelpContents page.

Advanced Features

4As you edit the wiki you will learn how to use the power of the wiki software to do even more clever things! Here are some examples:

• To see almost all the wiki's formatting in action, have a look at the syntax reference page.
• Inserting Icons - see IconsPage
• Inserting a table of contents such as what you see at the top of this page:
  • ||<tablestyle="float:right; font-size: 0.9em; width:40%; background:#F1F1ED; margin: 0 0 1em 1em;" style="padding:0.5em;"><>||
• To insert a simple table of contents, without the box around it, just use: <>

HelpForUsers > HelpOnEditing

Page Editing

Names of pages may either LookLikeThis (that is called a WikiName) or [[Like this]] (a so-called free link). If you write a word that LookLikeThis, it will be automatically turned into a link. More details about this you find on HelpForBeginners.

The following pages describe the elements (wiki markup) you can use to get special formatting effects:

• HelpOnFormatting - general text formatting rules
• HelpOnLinking - external hyperlinks and inline images
• HelpOnHeadlines - section headings
• HelpOnRules - horizontal rules
• HelpOnLists - lists and indented sections
• HelpOnTables - tables
• HelpOnDictionaries - dictionaries
• HelpOnSmileys - how to insert a
• HelpOnMacros - Macros allow you to use dynamic elements in a page
• HelpOnParsers - data processing parsers (replaces Processors)
• HelpOnProcessingInstructions - how to influence page formatting
• HelpOnVariables - how variables work (built in and self-defined)
• HelpOnXmlPages - how to store pages with XML content and process them via XSLT
• HelpOnEditLocks - how to behave correctly when edit locking is activated
• HelpOnCategories - how to group wiki pages
• /SubPages - how to group together related information

To experiment with wiki markup, go to the WikiSandBox and then click on "Edit****Text" at the bottom of the page. Use your browser's "open a new window with this link" feature on the word "WikiSandBox", so you can keep the help pages open side-by-side to the editing window.

Automatic Backup of Drafts

Every time you are in the editor and use the "Preview", "Spell Check", "Cancel" or "Save Changes" buttons, moin saves a draft copy of your work internally. Use preview often!

If you hit "cancel" accidentally, your machine crashes, or the browser window was accidentally closed, then the automatic backup of your draft may be easily recovered.

To recover that draft, you simply edit that page again. If there is a draft, an alert message will be in the message box and a "load draft" button will be present. Clicking the "load draft" will load your saved draft into the editor box replacing the current revision already loaded. You can continue editing the loaded draft, but this time try to save it at the end.

Don't use the "preview", "spell check", "save changes" or "cancel" buttons on that page before "load draft" or you will overwrite your old draft with a new one.

If you successfully save a page, the internal draft copy of it is not needed any more and will be deleted.

WikiGuide/PageCreation - Community Help Wiki

Introduction

This section deals with how to create pages on the Ubuntu wiki.

Search and Integrate. Don't Duplicate.

Before adding a page to the wiki, make sure you do a comprehensive search.

Search

• RecentChanges - See where people are currently working.
• FindPage - Search or browse the database in various ways.
• TitleIndex - A list of all pages in the wiki.
• WordIndex - A list of all words that are part of page titles.
• Category List - A list of categories that can be selected to list pages in a particlular category. These also list the pages with the category name in the title.

Integrate

• Don't add another page if a guide, article, or document already exists on a particular subject.
• If you think the existing document could be better, is out of date, or missing something, then improve it!
• Either add or integrate the material with the existing page in the appropriate place.

New Pages

If no such article exists, please feel free to create a new page.

Choose a Name

Choosing a good name is very important to ensure that a user who is searching for the page will find it easily. So:

1. Choose a descriptive name
2. Choose a name with some capital letters (such as WikiName). This will ensure that the page has a similar style of name to the existing pages.
3. Avoid using the word "Howto" in the page title. Everything here is a howto!
4. Do not use spaces or dashes in the name.

Create the Page

There are several ways to create a new page but all of them require that you first Log-in

By visiting the page

1. Type the address for the new page into the address bar of your browser. Since the page does not exist because you performed the searches discussed above, MoinMoin will suggest to create it.
2. Select a template from the left side of the page that opens. DocumentationTemplate is a default template you can use for any page. There are also some specialized templates to choose from.

Add a link on another page

1. Edit another page
2. Add a link to the new page, preferably like this: [[PageName|Page Name]]
3. Save the page and click the new link
4. Click one of the template names
5. Edit your new page and save it

For more information on linking to other pages, see HelpOnLinking.

By using the NewPage macro

1. Enter the page name in the text box and click "Create New Page"
2. Edit your page and save it

By using the GoTo macro

1. Enter the page name in the text box and click "Go To Page"
2. Click "Create new page"
3. Edit your page and save it Advanced To learn about creating and using template pages see HelpOnTemplates. To learn more how to set variables see HelpOnVariables Go back to WikiGuide

WikiGuide/Screenshots - Community Help Wiki

The use of screenshots in documentation is encouraged. However, we ask that you follow a few basic guidelines when introducing screenshots:

• Do not try to use very big images - these crowd the page and confuse the user.
• Attempt to integrate the screenshots into the formatting of the page.
• Use the default Ubuntu Ambiance theme for screenshots.

See for example the following pages which contain examples of good use of screenshots: Photos/CorrectColor, Photos/RetouchPhotos

Some information about how to take screenshots can be found at https://wiki.ubuntu.com/TakingScreenshots although this page may be out of date.

To upload an image:

1. Open the wiki page in your browser

5. To display the file on the wiki page, type {{attachment:filename.png}} where you want the image to appear.

For greater details on uploading and managing screenshots using the wiki software, see HelpOnActions/AttachFile.

WikiGuide/WritingGuide - Community Help Wiki

Introduction

The pages in this wiki should be as easy to understand as possible and follow. With this in mind, please take into account the following suggested writing style guidelines:

Terminology

• Ubuntu releases - Always try to specify which versions of Ubuntu a page is valid for. When referring to Ubuntu releases, use "Ubuntu X.XX (Nickname)" or "Ubuntu X.XX" - eg:"Ubuntu 5.10 (Breezy Badger)" or "Ubuntu 5.10", rather than just "Breezy" or "Ubuntu Breezy".
• Operating Systems - Capitalize the names of operating systems like Linux, Ubuntu, Windows, etc.
• Repositories - Capitalize the names of the Universe & Multiverse repositories when you use them.
• Installing software - When documenting how to install software, try to avoid recommending a particular package manager (such as apt-get) - instead, simply use an apt link to allow the user to click on the link to install the relevant package. So, for example:
  • To enable support for mp3s in Ubuntu, install the ''Ubuntu-restricted-extras'' package.
  • The wiki markup used to make the link in that example is: [[apt:Ubuntu-restricted-extras|install the ''Ubuntu-restricted-extras'' package]].

Page Titles

• Be descriptive.
• Avoid using the word "How to" in the page title (everything here is a how to).
• Use capital letters and avoid spaces or dashes (WikiName, for example). The wiki software permits us to use page titles like this but to display the page title with spaces. In order to achieve this effect, when creating the page, give the page title a name without spaces, and then begin the content of the page with the following:#title Page Name This will ensure that the page title will appear with spaces when people view the page.

Section Headings

• Heading text should be short, clear, and descriptive.
• Capitalize in the following manner:
  • Initial uppercase letter for the first word and the last word, regardless of part of speech
  • Initial uppercase letter for all nouns, adjectives, and verbs
  • Initial uppercase letter for conjunctions of four letters or longer
  • Initial uppercase letter for prepositions of four letters or longer
  • Initial uppercase letter for prepositions that are part of a phrasal verb
  • All lowercase letters for conjunctions, articles, and prepositions of less than four letters
  • (Taken from the GNOME Style Guide)

Links

• Use friendly text when creating links. For example, to link to the page Drives And Partitions, use [[DrivesAndPartitions|Drives and Partitions]] so that the link will appear like this: Drives and Partitions.

Lists

• Bullet lists of links should take the following form: .
• For example:
  • Skype - Internet telephony software (closed source).

WikiGuide - Community Help Wiki

Introduction

This page contains guidelines and help on how to contribute to the documentation in this wiki.

Contributing

Anyone can edit the Community Help Wiki. You just need a Launchpad account (see /Registration) and be a member of the ubuntu-wiki-editors Launchpad team. Once your membership has been approved (a confirmation email will be sent in approximately 1-7 days), log out of the wiki and then log back in. Don't forget to tick "Team membership: ubuntu-wiki-editors" when logging back in if asked what information to share.

Please note that there are two wikis where this applies, and to which you need to log in separately:

• https://help.ubuntu.com/community (to which this page belongs)
• https://wiki.ubuntu.com

Basics

If you haven't contributed to the wiki before, these are the best pages to start with.

• /PageCreation - Guidance on creating pages on this wiki

• SandboxPages - Info on creating sandbox pages to test wiki pages
• Tags - Tags are used to label pages as requiring attention from Wiki Editors
• Categories - A list of categories pages can be listed under

Wiki Markup

This website is a wiki, and therefore uses wiki markup to define how text should be displayed, to make links to other pages and websites, and to add images to pages. Wiki markup is really easy to learn.

• WikiGuide/Formatting - Help on getting started with wiki markup.
• Wiki Icons - describes availability & use of icons in the Ubuntu wiki

This should be enough to get started, but as you get more comfortable with the wiki as and want to try more advanced features, have a look at the "Advanced Reference" section below.

UbuntuStudio/FindingSoftware - Community Help Wiki

Finding Multimedia Software

Finding additional software for Ubuntu Studio can be done in numerous ways and from various sources.

Finding Software From the Ubuntu Repository

Using Software Center

The Software Center is the default Ubuntu software manager, and is the easiest way for new users to browse and look for new software. All the software listed there is available to you through the common Ubuntu Repository where all the official Ubuntu packages lives, including all the Ubuntu Studio related packages.

While you will find that you can find mostly everything you need using Software Center, not everything in the Ubuntu repository is installable from there. In those cases, you will need to use either Synaptic or Apt at the command line.

Synaptic Package Manager

Synaptic is no longer installed by default on Ubuntu, so you will need to first install it to make use of it. It is a bit more technical, but once you get the hang of it, you might prefer it to the Software Center.

apt-cache

Apt is a great command line tool for searching for packages. Open a terminal and type: apt-cache search ubuntustudio, and you will get results of all the packages installable that relate specifically to Ubuntu Studio. (see FAQ about using the terminal)

Once you find a package you like, install it with: sudo apt-get install

Ubuntu PPA

Sometimes you will find that an application does not exist in the Ubuntu repository, or that you would like to install a custom version of that application. Often you will find such applications on separate PPA's (personal package archives), which are available at Launchpad.

If you have found a PPA repository that you would like to use, you will find the instructions for adding the repo to your system and making those packages installable on the same page. Generally, it is something like sudo add-apt-repository

Separate Ubuntu Packages

Sometimes applications will only be found on their specific websites. The easiest way to install an application manually is to find a Ubuntu .deb package for it, download it, and double-click to start the installation.

UbuntuStudio/RealTimeKernel - Community Help Wiki

About RealTime Kernels

Early on in Linux audio production, Real-Time kernels were the only way to get low- and no-latency audio for professional audio applications. However, since Linux 2.6, the real-time stack has been part of the Linux kernel, having a kernel patched with a real-time stack is no longer necessary.

RealTime Kernels Still Exist

However, there continued to be a demand for real-time kernels with a special patch. A patch does exist to enable process to have real-time process access to any process requesting it. This is good for applicance-like applications, such as audio mixers that use Linux (the Behringer X-series mixers and the Allen & Heath iLive series mixers are good examples). For desktop computer use, THIS IS A BAD IDEA.

Security Implications

All it would take is one malicious process to execute and take advantage of the real-time code to completely lock-out a user from their machine, turning that machine into part of a botnet or other malicious purpose. Real-Time processes have the potential to completely take-over a machine. This is the number one reason Ubuntu does not carry a Real-Time kernel.

Low-Latency Kernel

The Low-Latency Kernel included in Ubuntu Studio (and available in the Ubuntu repositories) does not allow such malicious code from locking-out a user from their machine. It does contain other optimizations, such as Preempt-RT being enabled in the kernel configuration, to achieve the lowest possible latency for audio and other applications, while keeping the user interface usable. Latency as low as 0.1 millisecond can and has been achieved using this kernel.

Summary

For desktop computer usage, using a real-time kernel can cause security nightmares. The low-latency kernel included in Ubuntu Studio is completely capable of low- to no- latency while not enabling malicious processes to lock-out a user from their computer.

UbuntuStudio/TroubleShooting - Community Help Wiki

TroubleShooting Q/A

Help! JACK is not able to shut down cleanly

If the audio session gets stuck, use Ubuntu Studio Audio Configuration to restart or reconfigure the audio stack, or log out and back in. Current releases use PipeWire for desktop audio, so the old JACK-specific workaround is no longer relevant.

killall -9 jackd

If you can start jack, but there's no sound, there are two likely reasons for this.

1. If you have multiple audio devices, you need to make sure to choose the right device after each boot in Qjackctl -> Setup -> Interface
2. Your audio device is muted, but the controls aren't visible in the desktop mixer. For PCI and USB, use alsamixer or a specific mixer for your device. For FireWire use ffado-mixer.

UbuntuStudio/UbuntuStudioInstaller - Community Help Wiki

Ubuntu Studio Installer

Ubuntu Studio Installer adds Ubuntu Studio's package selections and workflow tools to an existing installation of Ubuntu or an official Ubuntu flavor.

It does not convert the system into Ubuntu Studio. It installs curated packages for creative work while leaving your existing desktop flavor in place.

Installing

Install Ubuntu Studio Installer on a supported Ubuntu flavor:

sudo apt install ubuntustudio-installer

Unofficial Ubuntu derivatives and Ubuntu Server are not supported.

Using Ubuntu Studio Installer

• Open Ubuntu Studio Installer from the application launcher.
• Select the package groups you want for audio, graphics, video, publishing, or photography workflows.
• Click Install or Modify Installed Package Selection.
• If prompted to log out and back in after installation, do so to apply real-time audio permissions.

This tool is the supported way to add Ubuntu Studio's workflow packages to another official Ubuntu flavor without replacing that flavor's desktop.

Current documentation

For the latest screenshots and workflow details, see the current Ubuntu Studio website:

UbuntuStudio/UsingTheTerminal - Community Help Wiki

Using The Terminal - Basic Guide

Sometimes it may be practical to know how to use the terminal, most likely when following tutorials where you need to use the terminal.

Here is a short guide on how to perform some basic commands on the terminal.

To start a terminal, go the menu and choose the Terminal Emulator

Starting an application, and using the Tab key

To start an application from the terminal, just type the name. Let's start gedit, and use Tab to complete the name.

First, type ged as done below

user@host:~$ ged

Press the Tab key to auto-complete the name. It should now read:

user@host:~$ gedit

Press Enter to start gedit from the terminal. Before continuing, quit gedit.

Installing applications

Installing applications from the terminal is easily done using apt-get. To search for applications, we use apt-cache. Both belong to the same program called apt.

Search for videolan:

user@host:~$ apt-cache search videolan

You should get a long list of packages related to videolan. To install vlc-plugin-jack (will allow you to use vlc with jack):

user@host:~$ sudo apt-get install vlc-plugin-jack

What is sudo?

Sudo is a command that lets' you perform other commands as 'superuser'. Installing programs is not allowed for a normal user. When using sudo, you need to use your user password to allow passing the command that follows it.

More basic commands, and starting scripts

Up and Down Arrow Keys

You already know how to use the Tab key, which saves you a lot of effort when typing. Other helpful keys are the up and down arrow keys. Pressing up will page back in history of the commands you have used. Pressing Down will page forwards.

Download a script

This script is called myscript.sh, and the only thing it does is prints some text when you execute it from the terminal. Download it into your Download folder.

Change to another directory and start the script

Now, if you downloaded the script into your Download folder in your user home directory, you could do following to start it from the terminal.

Try the ls command:

user@host:~$ ls

You should see a list of files and folders in your home directory. To change to the Downloads directory use the cd command:

user@host:~$ cd Downloads

Notice that the prompt looks different now:

user@host:~/Downloads$

Now, you could do ls again to see what is in the Downloads directory. And to start the script, you do:

user@host:~/Downloads$ ./myscript.sh

If you aren't able to start the script, it may be that it isn't set to be executable. To make the script executable, do:

user@host:~/Downloads$ chmod +x myscript.sh

And then, try again.

Finally, to get back to your home directory you can do:

user@host:~/Downloads$ cd ../

Also, just using cd without an argument will get you back to your home directory.

How to find help about different commands

Each command usually has one or two help sections. To see a shorter help section for the ls command, do:

user@host:~ ls --help

To get the more extensive manual, do:

user@host:~ man ls

To quit the manual, press q.

That's all for this short guide. Hopefully you have learned enough about using the command line to know how to follow simple tutorials and guides that involve the terminal.

Historical import note: this page documents an older Breathe icon effort. Current Ubuntu Studio systems use the Papirus icon theme with Papirus Colors variants. You can find practical examples of these icons and color variants on current Ubuntu Studio installations.

UbuntuStudio

This page will be the development page for the Ubuntu Studio variant of Breathe currently target for a Lucid Lynx release.

Current Icons

So, the idea is to use these as examples and create new one in the Breathe/Oxygen style. This set will inherit Breathe as a dependency.

Guidelines

• Folders must lay on side.
• Blue used is: #204a87 on the folders and #009bf9 on the logo. One of these 2 blues must be the primary blue used.
• All icons must match stylistically with the current Breathe icons.

Ubuntu Open Week - Ubuntu Studio - Cory Kontros - Sat, Oct 27, 2007

18:07 <+_MMA_> Hi all. My name is Cory Kontros and I'm the lead on Ubuntu Studio. http://ubuntustudio.org My intro will be short. I'll post info with pauses so people can read. Then I'll open it up to questions.

18:07 -!- mode/#ubuntu-classroom [-v atoponce] by Vorian

18:07 <+_MMA_> Our project aims to bring together the best in the free-software world for multimedia production as well as spotlight these applications and help them gain a wider audience. We also work to maintain a good relationship with upstreams and the Debian-multimedia team as this will only better that apps in Ubuntu Studio and raise the bar for Linux multimedia creation as a whole.

18:08 <+_MMA_> The project started from a couple of Ubuntu users that were also users of DeMuDi. http://en.wikipedia.org/wiki/DeMuDi The project started simply as a guide for Dapper (https://help.ubuntu.com/community/UbuntuStudio/DapperPreparation) but was expanded to be a true Ubuntu-based, DeMuDi replacement. Simple beginning. :)

18:08 <+_MMA_> I will be sighting info from our Wiki page. https://wiki.ubuntu.com/UbuntuStudio

18:08 <+_MMA_>  

18:09 <+_MMA_> Our project provides packages suites of applications geared toward specific tasks.

18:09 <+_MMA_>  * Audio - All applications deemed necessary to provide a working PC studio environment.

18:09 <+_MMA_>     * Audio-Plugins - A collection of DSSI and LADSPA plugins.

18:09 <+_MMA_>  * Video - A collection of various video editing/creation apps.

18:09 <+_MMA_>  * Graphics - A collection of 2D/3D manipulation applications and plugins.

18:09 <+_MMA_> A listing of packages can be found: https://wiki.ubuntu.com/UbuntuStudio/PackageList

18:09 <+_MMA_>  

18:09 <+_MMA_> With our Gutsy release we have also met 4 of our major goals.

18:09 <+_MMA_>  * Provide a true realtime patched kernel.

18:09 <+_MMA_>  * Support AMD64.

18:09 <+_MMA_>  * All packages in the Ubuntu proper repos.

18:09 <+_MMA_>  * Clean up the "Sound&Video" menu.

18:09 <+_MMA_> The team feels these will go along way toward improving the Ubuntu Studio users experience.

18:09 <+_MMA_>  

18:10 -!- mode/#ubuntu-classroom [+o PriceChild] by ChanServ

18:10 -!- mode/#ubuntu-classroom [-o Vorian] by PriceChild

18:10 <+_MMA_> We are a very small team an are always on the lookout for people who can give solid help. Currently we are looking for people to help with:

18:10 <+_MMA_>  * ISO testing

18:10 <+_MMA_>  * Documentation

18:10 <+_MMA_>  * Artwork for Gutsy. Artwork/OfficialHardy (this includes all aspects for the "look&feel of Ubuntu Studio-Gutsy as well as the website.)

18:10 <+_MMA_>  * Knowledgeable help with packaging and technical issues around Linux audio.

18:10 <+_MMA_> The front page of our wiki gives various ways to contact us about involvement. https://wiki.ubuntu.com/UbuntuStudio

18:10 <+_MMA_>  

18:11 <+_MMA_> So with that I'll open it up. :) Please post questions to #ubuntu-classroom-chat prefixed with "QUESTION:"

18:11 <+TheMuso> c

18:11 <+TheMuso> ugh

18:11 <+TheMuso> sorry

18:11 < mzungu> join #ubuntu-classroom-chat

18:13 <+TheMuso> desertc: Thereis no upgrade path, as it uses ubuntu Gutsy as base. If you only want to install either audio, audio plougins, video, or graphics, you only need in stall the ubuntustudio-audio, -video, -graphics, or -audio-plugins as needed.

18:14 <+_MMA_> ? I didnt see the question here.

18:14 <@PriceChild> TheMuso, you might want to paste the questions you're answering in here so the logs are nice :)

18:14 <+TheMuso> The ubuntustudio-desktop brings in the GNOME desktop, much like ubuntu-desktop does. if you are already running gutsy, you likely won't want to do this, as you already have a desktop.

18:14 <+TheMuso> PriceChild: Ok.

18:14 <+_MMA_> SOmeone handle the questions please.

18:15 <+_MMA_> "awkorama_: QUESTION: what's your view of NLE software for linux? what new video software is included in gutsy?"

18:15 <+_MMA_> Currently this is a big thorn in many sides.

18:15 <+TheMuso> desertc asked:  Is there an upgrade path from Ubuntu Gutsy standard install to Ubuntu Studio?

18:15 <+TheMuso> My answer is above.

18:16 <+_MMA_> NVE are really lacking.

18:16 <+_MMA_> Cinelerra is the best thing we have going but has many license issues.

18:16 <+_MMA_> Its a really complex app to develop.

18:17 <+_MMA_> Ardour has had success with audio because of a great team and financial support over the years.

18:17 <+_MMA_> But sadly this hasnt happened for NVE.

18:18 <+TheMuso> < mzungu> QUESTION: hi - is it ok to use kubuntu as the base system? -- mzungu, of course. There is nothing stopping you from using Kubuntu as a desktop.

18:19 <+_MMA_> mzungu: Sure. Wont hurt anything. :)

18:19 <+_MMA_> You *should* be able to use any *buntu you want with our packages.

18:20 <+TheMuso> < FayZee> QUESTION: (Following on from desertc) can i upgrade from Ubuntu 7.04 if I first uninstall the Gnome desktop? If  so, how / what CLI command - uninstall or purge or whatever?? - FayZee_  -- You shouldn't need to uninstall GNOME to upgrade to UbuntuStudio gutsy.

18:21 -!- mode/#ubuntu-classroom [+v jussi01] by ChanServ

18:21 <+TheMuso> FayZee_: Since a lot has changed, and while many have had success, we recommend a fresh install of UbuntuStudio.

18:21 <+_MMA_> <desertc> QUESTION: Back to my comment about user-generated-content being the killer-app of Linux, Is Ubuntu Studio leading users to use Free file formats, or at least educating them about using non-Free codecs?  I imagine most people want to make and edit MP3 and AVI files, only because the know of the file formats.

18:21 <+TheMuso> FayZee_: Note also that you will need to remove the extra repo needed for Ubuntustudio Feisty from your /etc/apt/sources.list file.

18:21 < popey> opme

18:21 <+_MMA_> We do prefer free formats where we can.

18:22 <+_MMA_> We ship no support for them by default following the same line as Ubuntu proper.

18:22 <+TheMuso> ^/c

18:23 <+TheMuso> < mzungu> QUESTION: in relation to my last question - i was thinking about audio latency issues with arts - so a kubuntu  desktop will still do the job?

18:23 <+TheMuso> mzungu: You just need to kill artsd before you use any audio app that might need to use Jack for example.

18:23 <+TheMuso> But yes, Kubuntu as a desktop is fine.

18:24 <+TheMuso> Any more questions?

18:24 <+_MMA_> hehe. Gonna be a short one. :)

18:25 <+jussi01> <desertc> QUESTION: Do you offer packages or advice on how Ubuntu Studio users can publish their work?  Is there any server-services that could be used to publish user-generated media on a high-speed Internet connection?

18:25 <+_MMA_> desertc: Currently no. We're open to ideas. :)

18:25 <+TheMuso> I don't know of any, but others may... Guys?

18:26 <+jussi01> <desertc> QUESTION (cont): I am thinking of pod-casting, and video-casting, as well as advise on where to put picture collections.

18:27 <+jussi01> <awkorama_> QUESTION: is there any chance, that I won't get 90 audio apps when installing ubuntu studio, but get one to get a job done (think of ubuntu-desktop, it does not kill user by giving him 100 apps right away)

18:27 <+TheMuso> awkorama: As I said earlier, you can install ubuntustudio-audio to install a selection of audio applications.

18:27 <+_MMA_> awkorama_: You will get the audio apps installed by ubuntustudio-audio.

18:28 <+TheMuso> awkorama: But if you only want to install a few apps, you are better off finding the apps you need, and installing them.

18:28 <+_MMA_> We have tried to really pair it down via user feedback when we started.

18:29 <+jussi01> <desertc> QUESTION: Have you seen Ubuntu Studio used in any organizations worth mentioning?

18:29 <+_MMA_> But if you're looking for a single app its best to use U/K/Xubuntu ans grab what you want.

18:29 <+_MMA_> desertc: Id have to dig for some emails but I would saw the short answer is no. :)

18:30 <+_MMA_> I have a school using it and someone mentioned using it at their work but thats about it. :)

18:31 <+_MMA_> *crickets*

18:31 <+_MMA_> :)

18:32 <+jussi01>  <desertc> QUESTION: Does Ubuntu Studio have DVD video encoding?  Can I make burn my own digital movies to DVD like Apple iFilm?  If not, then what do you see as the roadblocks

18:33 <+_MMA_> desertc: Currently no. We are looking at some to make sure there are no license concerns.

18:33 <+TheMuso> Proprietary codecs.

18:33 <+_MMA_> We're happy to take any suggestions on the matter.

18:34 <+TheMuso> Don't forget that the large majority of codecs in use for things like DVD today, are patent encumbered.

18:34 <+_MMA_> Like I said, we're a small team and welkcome help. ;)

18:34 <+TheMuso> And/or require royalties.

18:34 <+_MMA_> *welcome

18:35 <+jussi01> <desertc> QUESTION: Have you thought about educational uses of this software, for classes that teach about multimedia in their intro to  computers class?

18:35 <+TheMuso> As a development team, I don't see that as our concern at this point.

18:35 <+TheMuso> If users wish to do that, they are most welcome to.

18:36 <+TheMuso> DVDs use MPEG for the video, which has patents/royalties as far as I know.

18:36 <+_MMA_> Sure, problem is, that its really hard to use some of our tools in the "normal world" because of the proprietary nature of broadcasting.

18:36 <+_MMA_> So schools usually want AVID.Pro-Tools.

18:37 <+_MMA_> And though it can be done with our tools, its hard to get them to look at us.

18:37 <+TheMuso> < popey> does ubuntustudio do mp3 encoding?

18:37 <+TheMuso> < popey> if so then the patent argument aobut dvd is somewhat irrelavent

18:37 <+TheMuso> Not by default, no.

18:38 <+TheMuso> You need to install an MP3 encoder from the multiverse repo to do that.

18:38 <+_MMA_> We follow the same "party line" as Ubuntu proper.

18:38 <+jussi01> <desertc> QUESTION: Thought about the upcoming GNASH project and incorporating an open flash development tool set?

18:39 <+jussi01> desertc: does one exist?

18:39 <+TheMuso> I personally dislike flash greatly, so wouldn't recommend encouraging a proprietary format.

18:39 <+TheMuso> I don't know of one that exists so far.

18:39 < luisbg> gnash playbacks flash, doesn't edit it

18:39 < luisbg> no free flash editor is even plausible right now

18:39 <+TheMuso>  But at the end of the day, its not my call whether it goes in or not.

18:40 <+jussi01> <desertc> QUESTION: How has the alpha-status of the OGG video codec, Theora, effected the tools you include in Ubuntu Studio?

18:40 <+TheMuso> We just include them. The only way things get better, is if users use/test them, and file bugs.

18:40 <+TheMuso> And, theora is the most ree of video codecs atm afaik.

18:40 <+_MMA_> Not so much only that I keep am keeping a better eye on then to make sure we get the newest packages in we can.

18:41 < luisbg> the alpha-status is a label they have, the quality is very good and could be definitive

18:41 <+jussi01> <desertc> QUESTION: What is your most favorite feature in Ubuntu Studio?  What's the most fun you've had on the team?

18:41 < luisbg> but some projects tend to dilate the alpha label, specially if there is no money behind release a "final product"

18:41 <+TheMuso> Realtime kernel + Jack + 3 soundcards simultaneously. :p

18:42 <+_MMA_> Hmm... Ardour2 and our -RT kernel. :)

18:42 <+TheMuso> I've had fun doing everything that I've done for the project/team.

18:42 < luisbg> -rt kernel has given us real fun times, no doubt

18:42 <+_MMA_> And our cleaned up Sound&Video menu. :)

18:43 <+_MMA_> Its dived into submenus now to help with the mile-high menu.

18:45 <+joejaxx> and amd64 support :)

18:45 <+_MMA_> Ahh..

18:45 <+_MMA_> Yes. :)

18:45 <+_MMA_> +1 for Joe

18:45 <+jussi01> <BonesolTeraDyne> QUESTION: How far do you think video editing in Linux has come compared to, say... last year? Also, how long do you think it will be until we get something that has achieved the level that Adobe Premier or iMovie has gotten to right now?

18:46 <+_MMA_> Not far at all. Its a fairly complex thing to pull off and alot of the devs that do them sadly work alone.

18:46 < popey> pitivi is coming along very nicely

18:46 <+_MMA_> I have been talking with the 64Studio guys to see what we can do.

18:47 <+_MMA_> We have a long way to go to get to Adobe Premier or iMovie.

18:48 <+_MMA_> pitivi is coming along but Open Movie Editor looks to be making more progress.

18:48 < luisbg> I believe the real problem is in the bass... gstreamer and openlibs aren't ready for video heavy duty

18:48 <+_MMA_> This is something we will be heavily looking at in the Hardy cycle.

18:48 < luisbg> but progress in that side is being made day after day

18:50 <+jussi01>  <imbrandon> QUESTION: how much MT. Dew and $other_caffeine do you guys go though close to a release :P

18:50 <+_MMA_> Personally, none. :) Joe might though.

18:50 <+TheMuso> None here. Just get good rest, and be sure I know what I'm doing, why I'm doing it, and how much time I have to get it in.

18:51 <+TheMuso> And whether its likely to break something.

18:51 < luisbg> I don't drink coffee... mabe tea

18:51 <+joejaxx> i only drink cranberry juice :) it is great make sure you get the Ocean Spray

18:51 < luisbg> but if you were offerings drugs... I can give you my post adress

18:51 <+_MMA_> But Id really like to stress that this project is very much in that hands of its users.

18:51 <+joejaxx> luisbg: lol

18:51 <+joejaxx> _MMA_: yes the community is a big part

18:51 <+_MMA_> We need people to get involved in a constructive way.

18:52  * luisbg underlines constructive

18:52 <+joejaxx> _MMA_: and commitment

18:53 <+joejaxx>  /win 288

18:53 <+joejaxx> bah

18:53 <+_MMA_> We have had issues we took to the ML and forums and received feedback thats great. We also need suggestions and help from people who can carry out a plan.

18:54 <+TheMuso> If you wish to get involved with packaging, I suggest you first get involved with the MOTUs, (See other sessions), and then if you wish to help us further, contact us, and we'll have a talk.

18:55 <+_MMA_> Apart from new ideas people can help with testing ISOs. Writing HOW-TOs/Documentation. And our art is open to the community this time around.

18:55 <+_MMA_> Artwork/OfficialHardy

18:57 <+_MMA_> Well lets kill it then.

18:57 <+joejaxx> :D

18:57 <+_MMA_> Please feel free to contact us. https://wiki.ubuntu.com/UbuntuStudio

18:57 <+joejaxx> Thank you all for attending

18:57 < luisbg>  or #ubuntustudio

18:58 <+joejaxx> We hope to see your involvement in the upcoming release cycle :)

18:58 <+_MMA_> That link has all the info to get involved or just jump on IRC and chat.

18:58 <+TheMuso> We do attempt to have someone in all timezones, but there is also the users mailing list.

18:59 <+_MMA_> I personally wont be around in #ubuntustudio till tomorrow or Monday but feel free to hit me up when you see me.

18:59 <+TheMuso> I'll be on and off, depending on whether I can get my box at home up again, but I will be around this week as well.

18:59  * joejaxx is on all the time :)

19:00  * luisbg doesn't want to be distracted... just kidding, we are all open to chat when we are around

19:03 <+_MMA_> Ok. Thanx all. Im out. :D

The Ubuntu community desires to create a high quality Linux Distribution which appeals to a wide variety of user lifestyles and personal preferences.

Goal(s)

The goal is to solicit graphic designs in the form of illustrations or photographs to be used as wallpapers from the community targeted to the release currently under development.

Assumptions

• The Unity desktop, classic desktop, and humanity icon themes may be used.
• The collection of classic desktop themes may include themes which are generally described as light and themes which are generally described as dark.

Subject Matter

It is important to note Ubuntu is shipped to users from every part of the globe. Your images should be considerate of this diversity and refrain from the following.

• No brand names or trademarks of any kind.
• No illustrations some may consider inappropriate, offensive, hateful, tortuous, defamatory, slanderous or libelous.
• No sexually explicit or provocative images.
• No images of weapons or violence.
• No alcohol, tobacco, or drug use imagery.
• No designs which promotes bigotry, racism, hatred or harm against groups or individuals; or promotes discrimination based on race, gender, religion, nationality, disability, sexual orientation or age.
• No religious, political, or nationalist imagery.
• No version numbers as some may prefer to continue to use your theme with an older version of Ubuntu.
• No branding assets like “Ubuntu CoF” or text to permit use by derivative distributions.

Composition

• Your image should strive for subtlety and poetry.
• Regardless of the role or inspiration, the desired result of the successful submissions will render feelings which may be described as light, bright, or cheerful.
• Avoid high frequency images. ( A soft focus is one way to achieve this )
• As the name suggests, visually, it should settle into the “background” of the activity scene.
• Design must accommodate the Unity dock.

Constraints

• The final dimension should be 2560 x 1600 pixels.
• Submissions must adhere to the Creative Commons ShareAlike 3.0 license.
• Attribution must be declared if the submission is based on another design.

Submissions must adhere to the Creative Commons ShareAlike 3.0 license.

Specific comments and words of encouragement may be posted to Flickr or topics for discussion to the Artwork mailing list.

Please offer comments and discussions as guided by the Ubuntu code of Conduct.

Screen Resolution and Aspect Ratio

It is important to note the diversity of displays which Ubuntu needs to support. Although the desired image format is 2560 x 1600 pixels the composition should support a variety of image formats.

Background Guidelines

• Avoid prominent use of the Ubuntu logo. It appears in enough places already.
• No version numbers. Some individuals may desire to use an older theme, or use the latest theme in their older version of Ubuntu. Let your submission be about choice and do not use version numbers in your artwork.
• Avoid text, it calls for attention too much and will likely look bad when scaled. Plus it can't be translated easily.
• Be careful with small patterns, they might become uneven when scaled.
• Consider how the wallpaper will interact with the panels, icons and windows.
• Show restraint in your use of color tone and contrast. The wallpaper sets the scene for other elements, it is not the main act.

File Formats

• Use PNG format for bitmap files (ie any files in which fewer colors are repeated throughout, especially when the colors are in large blocks). Use JPGs for photos and final images in order to reduce the file size, as this format can cause visible compression artefacts.
• Make the XCF source files available, if you happen to work with GIMP
• Use SVG for vector art.
• Work generated with proprietary applications like Photoshop and Illustrator is acceptable, but files in their formats are useless for many of us.

Templates

An SVG template for use with Inkscape and an XCF template for GIMP. Both have a 2560 x 1600 pixel canvas to use the largest commonly offered resolution, currently. "Passepartout" layers allow to see how things will look when this space is cropped to conform to other common aspect ratios.

This simulates the effect the "Style: Zoom" setting in "Appearance Preferences: Background" will have: the image is scaled up or down such that it fills the screen without distorting it. If the aspect ratio of the image is wider than that of the screen, it will be scaled to the same height and the areas on the side will be cropped. If the aspect ratio of the image is taller than that of the screen, it will be scaled to the same width and the areas on top and bottom will be cropped.

Comments / Suggestions for this Document

The other aspect ratios should also be marked as "* Desired format(s)" ie. 2560x1440[16:9] and 2560x1920[4:3scaled] : The author should be the one to decide on where & what to crop out instead of GNOME's default crop's which sometimes give undesirable results like for example cutting the top off someone's head.

11.04release_notes

Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built for the GNU/Linux audio, video, and graphics enthusiast or professional.

The Ubuntu Studio team is very excited over its ninth release: Natty Narwhal 11.04, available as a 1.5GB DVD iso image from http://ubuntustudio.org/downloads/ Numerous improvements have been implemented for this release, but here are some of the more notable.

Installation tasks

The task selections during installation have been updated. The audio tasks have been parsed into two groups: generation and recording. The 'generation' task selections is focused more on synthesizers and sequencers (i.e. tone generation) and the 'recording' task focuses on recording live musician performances.

Kernel

Currently, Ubuntu Studio is shipping the -generic kernel. We are working with the Ubuntu Kernel Team to get a -lowlatency kernel into the archives which will then ship, in addition to the -generic kernel, in Ubuntu Studio. An interim -lowlatency kernel is available in Allesio Bogani's PPA.

If possible please report any testing results comparing the -generic kernel performance compared to the -lowlatency kernel performance at https://wiki.ubuntu.com/RealTime#Natty%20Benchmarks.

Network

Due to continuing problems, network-manager will replace gnome-network-admin. If performance degradation is experienced, please contact the Ubuntu Studio developer via email email or on IRC (#ubuntustudio-devel on freenode).

Package selection

The installed packages have changed. The packages shipped in Ubuntu Studio are more focused to support identified tasks and their derived work flows. Please note that this is a work in progress. If your favorite package is not include, please inform us about it and consider updating the task/work flows wiki page.

Unity

Ubuntu Studio does not currently use Unity. As the user logs in it will default to Gnome Classic Desktop (i.e. Gnome2).

ubuntustudio-controls

We were hoping to have -controls updated for Natty but it appears to we will not be done in time. Therefore we will be removing -controls from Natty as it's functionality is either not needed or broken.

We plan to continue working on it and hopefully SRU it into Natty later.

11.10release_notes

Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built for the GNU/Linux audio, video, and graphics enthusiast or professional.

The Ubuntu Studio team is very excited over its tenth release: Oneiric Ocelot 11.10, available as a 1.8GB (i386) or 1.9GB (amd64) DVD iso image from http://ubuntustudio.org/downloads/

Unfortunately, the Ubuntu Studio suffered an almost complete team fail during this cycle. This can be general categorized into two main reasons: normal, expected attrition experienced during most cycles and unforeseen circumstances that required team members to be absent.

Remember, none of the active Ubuntu Studio team members is a paid contributor or developer, we are all volunteer.

We apologize for any deficiencies in this release. But, you can always help us make the next one better

Kernel

Currently, Ubuntu Studio is shipping the -generic kernel. Excitingly, this kernel should allow users to set irq priorities, which means a real time kernel is no longer required for this task! Firewire users should be excited about this.

We are working with the Ubuntu Kernel Team to get a -lowlatency kernel into the archives which will then ship, in addition to the -generic kernel, in Ubuntu Studio. An interim -lowlatency kernel is available in Allesio Bogani's PPA.

If possible please report any testing results comparing the -generic kernel performance compared to the -lowlatency kernel performance at https://wiki.ubuntu.com/RealTime#Natty%20Benchmarks.

XFCE Transition

Some progress has been made but remains incomplete and not fully tested.

Unity

Ubuntu Studio does not currently use Unity as it is transitioning to XFCE.

New Features in Ubuntu Studio 12.04 LTS

Ubuntu Studio is the Ubuntu flavour designed for content creation.

It's produced as a DVD image that can also be converted to an USB stick and includes support for most languages by default.

Ubuntu Studio 12.04 LTS is a 3 year Long Term Support release and will be supported until April 2015.

Due to overwhelming improvements during this development cycle, the The Ubuntu Studio Team is very proud and excited to have users experience Ubuntu Studio 12.04 LTS and provide feedback. We look forward to hearing from you.

New features include:

• Live-DVD
• GUI-based installation
• lowlatency kernel installed by default
• i386 images use the lowlatency-pae kernel
• XFCE is default desktop environment
• Pulse Audio <-> JACK bridging enabled by default
• New theme, icons, and default font
• New LightDM and Desktop background/backdrop images
• Documented work flows/new application choices provide better user support
• Menu restructured for better work flow support
• ARandR included for improved multi-monitor functionality
• mudita24 replaces envycontrol24 for ice1712 chip audio interfaces
• Long Term Support release (3 years)

Pulse Audio <-> JACK bridging enabled by default

Lastly, the Ubuntu Studio website is currently under complete development and is expected to be release within weeks. Please bear with our current website until then.

Ubuntu Studio Applications

This cycle we focused on developing work flows based on user tasks. This should give a more complete, functional, and robust application tool chain for users to create content. Please note that not all work flows listed in the wiki are directly supported in a default installation.

Notable applications for audio/video/graphic/photography work flows include:

• JACK - lowlatency and flexible routing sound server
• Ardour - multitrack digital audio workstation
• qtractor - multitrack audio recorder and sequencer
• LADSPA/LV2 - audio plugins
• OpenShot - easy to use video editor
• Blender - 3D modeler and incredible video editor/compositor
• GIMP - powerful pixel-based image editor
• Inkscape - scalable vector graphics editor/creator
• Darktable - RAW digital photograph editor

OpenShot - easy to use video editor

Common desktop applications saw changes as well:

• gedit - text editor
• Ristretto - image viewer
• Firefox - internet browser
• Transmission - bittorrent client
• XChat - IRC client
• Audacious - audio player
• Totem - movie player
• Brasero - disc burner

Common Infrastructure

• Up until Ubuntu 11.10, administrator access using the sudo tool was granted via the "admin" Unix group. In Ubuntu 12.04, administrator access will be granted via the "sudo" group. This makes Ubuntu more consistent with the upstream implementation and Debian. For compatibility purposes, the "admin" group will continue to provide sudo/administrator access in 12.04.
• Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.
• pm-utils now has two new scripts to power down USB and various PCI devices in battery mode. A number of desktop packages were fixed to wake up less often. Both of these reduce power consumption and thus improve battery lifetime.
• resolvconf is now used to manage /etc/resolv.conf on all Ubuntu systems. You can learn more here
• Backports are now more easily accessible -- to enable users to more easily receive new versions of software, the Ubuntu Backports repository is now enabled by default. Packages from backports will not be installed by default — they must explicitly be selected in package management software. However, once installed, packages from backports will automatically be upgraded to newer versions.
• DVD Images -- the DVD images have been cleaned up significantly reducing their size to around 1.5GB to ease consumption. The remaining software remains available via download.
• As of 12.04.2, it is possible to install on UEFI systems with Secure Boot enabled (using signed versions of Shim, GRUB, and the Linux kernel). This is only currently set up for Ubuntu (desktop, alternate, and server) and Edubuntu images due to pressures of time.
• Both the 3.2 and 3.5 versions of the Linux kernel included as part of the 12.04.2 release have a workaround for 1040557, which bricked some models of Samsung laptops when installing Ubuntu in UEFI mode. (The underlying problem is a firmware bug, and may still be triggerable in other ways.)

Ubuntu Kernel 3.11

By default, the 12.04.4 point release will ship with a newer 3.11 Ubuntu kernel from Ubuntu 13.10, and a matching X.org stack. This is based on the 3.11.0 Extended Upstream Stable Kernel Release. The purpose of providing a newer kernel in the 12.04.4 point release is for hardware enablement. For more information regarding the 12.04.4 LTS Hardware Enablement Stack, please refer to:

• https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/UbuntuDesktop#LTS_Hardware_Enablement_Stack

https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/UbuntuDesktop#LTS_Hardware_Enablement_Stack

Upstart 1.5

Upstart has been updated to version 1.5. More details are available in the Upstart Technical Overview.

GNU Toolchain

Ubuntu 12.04 is distributed with a default toolchain that includes: GCC 4.6.3 (and changes from Linaro GCC 4.6-2012.02), binutils 2.22, eglibc 2.15, and Linaro gdb 7.4-2012.04.

Compared to the 11.10 release, the toolchain saw only incremental changes and bug fixes; comparing to the 10.04 LTS release, GCC updates include

• Updated frontends for better standards support (Ada 2012, Objective-C 2.0, improved experimental support for the upcoming C++0x ISO C++ standard, Fortran 2003 and 2008 improvements, new Go frontend)
• Improved optimizations, including better inter-procedural optimizations, and link time optimization (LTO).

Further information can be found upstream (GCC-4.6, GCC-4.5, binutils, gas, ld, gdb).

Python Toolchain

• Ubuntu 12.04 includes Python 2.7.3 and Python 3.2.3. Python 2.6 is no longer available for install.
• There is expanded support for Python 3 in this release, with Python 3 ports of python-dbus, python-feedparser, germinate, lazr.ui, wadllib, python-defer, python-keyring, and python-qt4 now included, among others.

Ubuntu 12.04 includes Python 2.7.3 and Python 3.2.3. Python 2.6 is no longer available for install.

Java Toolchain

The default run time for Java is OpenJDK 6b24 (IcedTea 1.11.1). OpenJDK 7u3 (IcedTea 2.1) is available in the archive as well.

Installation

Overview

Preparing your computer for Ubuntu Studio is now much simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.

You can now reinstall or upgrade an existing copy of Ubuntu Studio with the Ubuntu Studio DVD installer, provided that your computer is connected to the Internet.

Download

Ubuntu Studio 12.04 images can be downloaded from:

• http://cdimage.ubuntu.com/ubuntustudio/releases/precise/ (UbuntuStudio)

http://cdimage.ubuntu.com/ubuntustudio/releases/precise/ (UbuntuStudio)

System Requirements

The minimum memory requirement for Ubuntu Studio 12.04 is 512 MB of memory. It is highly recommended that you have 2GB or more memory though so that the system will perform much better. More information about other recommended hardware on the new Ubuntu Studio website when it is released.

Upgrading

Upgrading from Ubuntu Studio 11.10

To upgrade from Ubuntu Studio 11.10, press Alt+F2 and type in "update-manager" (without the quotes) into the command box. Update Manager should open up and display following message: "New distribution release '12.04' is available. Click Upgrade and follow the on-screen instructions".

Upgrading from Ubuntu Studio 10.04 LTS to Ubuntu Studio 12.04 LTS

It is recommended that users perform a complete instal rather than upgrade from Ubuntu Studio 10.04 LTS due to extent of the changes, including desktop environments.

Upgrading from Other Releases

Users of other Ubuntu Studio releases need to upgrade first to 11.10, and then to 12.04.

For further information on upgrading to 11.10, please see the Ubuntu Oneiric upgrade instructions.

Known Issues

Applications

Boot, Installation and Post-Installation

• Importing of existing Windows user accounts fails in some cases. (987902)

Importing of existing Windows user accounts fails in some cases. (987902)

• Wubi (the Ubuntu installer for Windows) is not available as an option on the Ubuntu Desktop/DVD any more. Instead, it is now a separate download.
• A bug in the firmware on certain Samsung laptop models leaves these machines at risk of being rendered inoperable ("bricked") when booted in UEFI mode. Steps have been taken with the kernel in 12.04.2 to mitigate this problem, but only a future firmware update from Samsung will resolve this issue with 100% reliability. It is therefore recommended that users boot their systems in CSM ("compatibility support module") mode to avoid this issue. (1040557)
• Performing automatic encrypted LVM installation using Kubuntu and Xubuntu 12.04.4 alternate installer images results in a failure to configure encrypted volumes. Please either use manual partitioning to create encrypted volumes with any non-default "IV algorithm" setting or use 12.04.3 media to complete the installation. (1276739)

Upgrades

• If you have overridden the value of APT::Cache-Limit in /etc/apt/apt.conf or /etc/apt/apt.conf.d, you should remove these settings before upgrading. The release-upgrader-apt used by update-manager for upgrades from lucid to precise no longer has any hard coded limit on the cache size.
• If you are running a KVM host with libvirt and are upgrading from Ubuntu 10.04 LTS to 12.04 LTS you may find that some existing virtual machines are no longer recognized (virsh list --all). A change to each guest's XML file may be needed, related to how console and serial devices are now configured. (931350)

9.04release_notes

Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built for the GNU/Linux audio, video, and graphics enthusiast or professional.

The Ubuntu Studio team is proud to announce its fifth release: Ubuntu Studio 9.04. With this release, which you can download in a 1.2GB DVD, Ubuntu Studio offers a pre-made selection of packages, targeted at audio, video and graphics users. Ubuntu Studio greatly simplifies the creation of Linux-based multimedia workstations.

For Ubuntu Studio 9.04 we have continued to update packages and fix critical bugs to better the Ubuntu Studio user experience.

We are happy to announce the real time kernel will be installed by default in Ubuntu Studio in this release, if the audio task is selected. We have tested it heavily and are happy with it's performance in audio environments.

The art has had a cool facelift. The gtk theme has been improved staying in the 'Studio' style. Plus the gdm theme has been switched to some great new eyecandy.

New applications included:

• FFADO firewire soundcard drivers
• Calf audio plugins
• LMMS (updated and included in the meta packages)

Features/Fixes/Improvements:

• Heavily tested 2.6.28 realtime kernel for low-latency audio work

• Jack Connection Kit upgraded to 0.116.1 (a major improvement)

• Ardour upgraded to 2.7.1

• Fresh ubuntustudio-looks improvements

• Addition to Ubuntu Studio Controls to allow users to maintain Ctr+Alt+Backspace behavior

• Ctr+Alt+Backspace behavior

See the Ubuntu release notes for other non Ubuntu Studio specific changes.

See http://calf.sourceforge.net/ for more information about CALF.

As our wiki page at UbuntuStudio states, "our aim is to make it more accessible for new users to get into the tools that GNU/Linux has to offer for multimedia creation and production. We also want to spotlight what's out there, and show users tools they might not know to exist."

Thanks to all who helped in Ubuntu Studio 9.04's creation!

• Brasero - ディスクバーナー

Transmission - BitTorrentクライアント

共通インフラストラクチャ

• Ubuntu 11.10までの「管理者」ユーザーは、「admin」Unixグループに所属することでsudo権限を付与されていました。12.04では、「管理者」ユーザーは「sudo」グループによって権限を付与します。これは、Ubuntuをアップストリームの実装やDebianに合わせたものです。互換性を維持するため、12.04では「admin」グループに所属していればsudoによる管理者特権アクセスが可能なままです。
• ハイバネート（suspend to disk）は、デフォルトでは無効になっています。これは、安定性の問題が見つかったことと、非常に遅いこと、そして二種類のサスペンドモードによって混乱が引き起こされるためです。812394 も参照してください。ハイバネートを有効にしたい場合、この手順を用いてください。
• pm-utilsパッケージに、新しく2種類のスクリプトが追加されました。バッテリー駆動時に、USBと、さまざまなPCIデバイスの消費電力を下げるためのものです。多くのデスクトップパッケージがこの挙動を妨害しないようにあわせて改良され、消費電力を低減させています。これにより、バッテリー駆動時間の向上が得られるでしょう。
• すべてのUbuntuシステムにおいて、resolvconfによって/etc/resolv.confが管理されるようになります。より詳細な情報はこちらで得られます。
• Backportsリポジトリが、これまでより容易に利用できるようになりました。これを用いることで、新しいバージョンへのアップグレードを簡単に行うことができます。Ubuntu Backportsリポジトリはデフォルトで有効になっています。ただし、Backports由来のパッケージは暗黙ではインストールされません。パッケージ管理ソフトウェアから明示的にBackports由来のソフトウェアを指定する必要があります。一度Backportsに含まれるバージョンを導入すると、以降はBackportsからより新しいバージョンのソフトウェアが自動的に導入されるようになります。
• DVDイメージ。DVDイメージの整理により、おおむね1.5GB程度の容量に縮小されました。DVDに含まれないソフトウェアは、ダウンロードによって入手できます。

Linux v3.2.14 Kernel

Ubuntu 12.04 LTSは、メインラインカーネルv3.0系から、v3.2系に更新されました。リリース時点では3.2.0-23.36カーネルが採用されています。このカーネルはアップストリームのv3.2.14 stable Linux kernelをベースにしています。メインラインカーネルv3.0からv3.2の間に、多くの新機能が追加されました。主要な点は次の通りです。

• ext4ファイルシステムが、より大きなブロックサイズをサポートします。
• btrfsファイルシステムに、データの完全性問題を改善するための改良が加わります。
• device mapperに、シンプロビジョニング機能と再帰的スナップショット機能が加わります。
• 大きなライトバック負荷が発生した場合のパフォーマンスが改善されます。
• 輻輳が生じているネットワークにおけるパフォーマンスが改善されます。
• ext3ファイルシステム上での移動操作が、ファイルシステムバリアを利用したものになります。
• メモリアロケータに改良が加わります。
• VFSのスケーラビリティが強化されます。
• iSCSIの実装が新しいものになります。
• Software RAIDの実装に、バッドブロック対応が追加されます。

11.10で採用されているUbuntuカーネル3.0.0-12.20からの更新点は、次の通りです。

• アップストリームのstable Linux kernel v3.2.14をベースとしています。
• amd64環境において、-genericと-serverカーネルフレーバーがマージされ、単一の -generic カーネルフレーバーになりました。これらのカーネル間にはわずかな差がありますが、LTSにおける長期間のサポート負荷から、統合を選択しています。
• サポート対象に、新しい armhf カーネルフレーバーを追加しています。
• 非SMP PowerPCカーネルフレーバーは削除されました。これまで非SMP PowerPCカーネルフレーバーがサポートしていたハードウェアは、SMP PowerPCカーネルフレーバーによってサポートされます。
• SandyBridgeシステムでは、RC6省電力機能がデフォルトで有効になります。RC6はGPUがアイドル状態のときに大きく消費電力を引き下げる技術です（0Wにまで下げられます）。これにより、RC6モードが機能している際は大きく電力を節約できます。アイドル時の消費電力を比較した場合、RC6を利用しないときに比べて、40〜60%の改善が見られました。
• jack detectionパッチセットを適用しています。これはv3.3系Linuxカーネルからバックポートされたものです。
• アップデートされたAppArmorパッチセットを適用しています。アップストリームに追加された、align調整を含みます。
• seccomp filter機能を追加し、有効にしています。これにより機械的な(BPFによる)パケットフィルタリングにより、システムコールへのアクセスを制限できます。
• v3.3-rc1カーネル由来の、ARM向けkexecの修正をバックポートしています。
• 「extensive review of Ubuntu kernel configs」で、これまでとの変更点を確認することができるでしょう。

Upstart 1.5

Upstartをバージョン1.5に更新しました。より詳細な情報が、Upstart Technical Overview（未訳）にあります。

GNU Toolchain

Ubuntu 12.04には、デフォルトのtoolchainとしてGCC 4.6.3 (Linaro GCC 4.6-2012.02の修正を追加したもの)、binutils 2.22、eglibc 2.15とLinaro gdb 7.4-2012.04が含まれます。

11.10と比較した場合、toolchainはマイナーバージョンの変更とバグフィックスだけが追加されています。10.04 LTSと比較した場合、GCCのアップデートが含まれます。

• より良い標準をサポートするため、フロントエンド実装が更新されています（次の実装を含みます。Ada 2012、Objective-C 2.0、ISO C++ standardに基づくC++0x（実験的サポート）、Fortran 2003と2008、Go）。
• 最適化が強化されました。inter-procedural optimizationsと、link time optimization (LTO)の強化を含みます。

より詳細な情報は、アップストリームの情報を参照してください(GCC-4.6, GCC-4.5, binutils, gas, ld, gdb)。

Ubuntu Studio 12.04 LTS

Ubuntu Studio is the Ubuntu flavour designed for content creation.

It's produced as a DVD image that can also be converted to an USB stick and includes support for most languages by default.

Ubuntu Studio 12.04 LTS is a 3 year Long Term Support release and will be supported until April 2015.

Due to overwhelming improvements during this development cycle, the The Ubuntu Studio Team is very proud and excited to have users experience Ubuntu Studio 12.04 LTS and provide feedback. We look forward to hearing from you.

New features in 12.04 include:

• Live-DVD
• GUI-based installation
• lowlatency kernel installed by default
• i386 images use the lowlatency-pae kernel
• XFCE is default desktop environment
• Pulse Audio <-> JACK bridging enabled by default
• New theme, icons, and default font
• New LightDM and Desktop background/backdrop images
• Documented work flows/new application choices provide better user support
• Menu restructured for better work flow support
• ARandR included for improved multi-monitor functionality
• mudita24 replaces envycontrol24 for ice1712 chip audio interfaces
• Long Term Support release (3 years)

Pulse Audio <-> JACK bridging enabled by default

Lastly, the Ubuntu Studio website is currently under complete development and is expected to be release within weeks. Please bear with our current website until then.

Ubuntu Studio Applications

This cycle we focused on developing work flows based on user tasks. This should give a more complete, functional, and robust application tool chain for users to create content. Please note that not all work flows listed in the wiki are directly supported in a default installation.

Notable applications for audio/video/graphic/photography work flows include:

• JACK - lowlatency and flexible routing sound server
• Ardour - multitrack digital audio workstation
• qtractor - multitrack audio recorder and sequencer
• LADSPA/LV2 - audio plugins
• OpenShot - easy to use video editor
• Blender - 3D modeler and incredible video editor/compositor
• GIMP - powerful pixel-based image editor
• Inkscape - scalable vector graphics editor/creator
• Darktable - RAW digital photograph editor

OpenShot - easy to use video editor

Common desktop applications saw changes as well:

• gedit - text editor
• Ristretto - image viewer
• Firefox - internet browser
• Transmission - bittorrent client
• XChat - IRC client
• Audacious - audio player
• Totem - movie player
• Brasero - disc burner

Common Infrastructure

• Up until Ubuntu 11.10, administrator access using the sudo tool was granted via the "admin" Unix group. In Ubuntu 12.04, administrator access will be granted via the "sudo" group. This makes Ubuntu more consistent with the upstream implementation and Debian. For compatibility purposes, the "admin" group will continue to provide sudo/administrator access in 12.04.
• Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.
• pm-utils now has two new scripts to power down USB and various PCI devices in battery mode. A number of desktop packages were fixed to wake up less often. Both of these reduce power consumption and thus improve battery lifetime.
• resolvconf is now used to manage /etc/resolv.conf on all Ubuntu systems. You can learn more here
• Backports are now more easily accessible -- to enable users to more easily receive new versions of software, the Ubuntu Backports repository is now enabled by default. Packages from backports will not be installed by default — they must explicitly be selected in package management software. However, once installed, packages from backports will automatically be upgraded to newer versions.
• DVD Images -- the DVD images have been cleaned up significantly reducing their size to around 1.5GB to ease consumption. The remaining software remains available via download.

Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.

Linux v3.2.14 Kernel

Precise 12.04.1 includes the Ubuntu 3.2.0-29.46 kernel. This release includes all the upstream stable releases up to and including 3.2.24. These upstream stable releases bring in 990+ commits that have been applied to the Precise LTS kernel. For details on what exactly was committed please see the kernel commit shortlog. Of special note, this release contains the fixes to the leap-second bug that affected a number of Linux kernels.

Upstart 1.5

Upstart has been updated to version 1.5. More details are available in the Upstart Technical Overview.

GNU Toolchain

Ubuntu 12.04 is distributed with a default toolchain that includes: GCC 4.6.3 (and changes from Linaro GCC 4.6-2012.02), binutils 2.22, eglibc 2.15, and Linaro gdb 7.4-2012.04.

Compared to the 11.10 release the toolchain did see only incremental changes and bug fixes; comparing to the 10.04 LTS release, GCC updates include

• Updated frontends for better standards support (Ada 2012, Objective-C 2.0, improved experimental support for the upcoming C++0x ISO C++ standard, Fortran 2003 and 2008 improvements, new Go frontend)
• Improved optimizations, including better inter-procedural optimizations, and link time optimization (LTO).

Further information can be found upstream (GCC-4.6, GCC-4.5, binutils, gas, ld, gdb).

Python Toolchain

• Ubuntu 12.04 includes Python 2.7.3 and Python 3.2.3 Python 2.6 is no longer available for install.
• There is expanded support for Python 3 in this release, with Python 3 ports of python-dbus, python-feedparser, germinate, lazr.ui, wadllib, python-defer, python-keyring, and python-qt4 now included, among others.

Ubuntu 12.04 includes Python 2.7.3 and Python 3.2.3 Python 2.6 is no longer available for install.

Java Toolchain

The default run time for Java is OpenJDK 6b24 (IcedTea 1.11.1). OpenJDK 7u3 (IcedTea 2.1) is available in the archive as well.

Installation

Overview

Preparing your computer for Ubuntu Studio is now much simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.

You can now reinstall or upgrade an existing copy of Ubuntu Studio with the Ubuntu Studio DVD installer, provided that your computer is connected to the Internet.

Download

Ubuntu Studio 12.04.1 images can be downloaded from:

• http://cdimage.ubuntu.com/ubuntustudio/releases/12.04.1/

http://cdimage.ubuntu.com/ubuntustudio/releases/12.04.1/

System Requirements

The minimum memory requirement for Ubuntu Studio 12.04.1 is 512 MB of memory. It is highly recommended that you have 2GB or more memory though so that the system will perform much better. More information about other recommended hardware on the new Ubuntu Studio website when it is released.

Upgrading

Upgrading from Ubuntu Studio 11.10

To upgrade from Ubuntu Studio 11.10, press Alt+F2 and type in "update-manager" (without the quotes) into the command box. Update Manager should open up and display following message: "New distribution release '12.04' is available. Click Upgrade and follow the on-screen instructions".

Upgrading from Ubuntu Studio 10.04 LTS to Ubuntu Studio 12.04 LTS

It is recommended that users perform a complete instal rather than upgrade from Ubuntu Studio 10.04 LTS due to extent of the changes, including desktop environments.

Upgrading from Other Releases

Users of other Ubuntu Studio releases need to upgrade first to 11.10, and then to 12.04.

For further information on upgrading to 11.10, please see the Ubuntu Oneiric upgrade instructions.

Ubuntu Studio 12.04.2 LTS

Ubuntu Studio is the Ubuntu flavour designed for content creation.

It's produced as a DVD image that can also be converted to an USB stick and includes support for most languages by default.

Ubuntu Studio 12.04 LTS is a 3 year Long Term Support release and will be supported until April 2015.

Due to overwhelming improvements during this development cycle, the Ubuntu Studio Team is very proud and excited to have users experience Ubuntu Studio 12.04 LTS and provide feedback. We look forward to hearing from you.

New features in 12.04 include:

• Live-DVD
• GUI-based installation
• lowlatency kernel installed by default
• lowlatency-pae kernel installed by default in i386.
• XFCE is default desktop environment
• Pulse Audio <-> JACK bridging enabled by default
• New theme, icons, and default font
• New LightDM and Desktop background/backdrop images
• Documented work flows/new application choices provide better user support
• Menu restructured for better work flow support
• ARandR included for improved multi-monitor functionality
• mudita24 replaces envycontrol24 for ice1712 chip audio interfaces
• Long Term Support release (3 years)

Pulse Audio <-> JACK bridging enabled by default

Ubuntu Studio Applications

This cycle we focused on developing work flows based on user tasks. This should give a more complete, functional, and robust application tool chain for users to create content. Please note that not all work flows listed in the wiki are directly supported in a default installation.

Notable applications for audio/video/graphic/photography work flows include:

• JACK - lowlatency and flexible routing sound server
• Ardour - multitrack digital audio workstation
• qtractor - multitrack audio recorder and sequencer
• LADSPA/LV2 - audio plugins
• OpenShot - easy to use video editor
• Blender - 3D modeler and incredible video editor/compositor
• GIMP - powerful pixel-based image editor
• Inkscape - scalable vector graphics editor/creator
• Darktable - RAW digital photograph editor

OpenShot - easy to use video editor

Common desktop applications saw changes as well:

• gedit - text editor
• Ristretto - image viewer
• Firefox - internet browser
• Transmission - bittorrent client
• XChat - IRC client
• Audacious - audio player
• Totem - movie player
• Brasero - disc burner

Common Infrastructure

• Up until Ubuntu 11.10, administrator access using the sudo tool was granted via the "admin" Unix group. In Ubuntu 12.04, administrator access will be granted via the "sudo" group. This makes Ubuntu more consistent with the upstream implementation and Debian. For compatibility purposes, the "admin" group will continue to provide sudo/administrator access in 12.04.
• Hibernate (suspend to disk) has been disabled by default, as it was found to be unreliable, very slow and confusing to have two suspend modes. See bug 812394 for details. If you want to re-enable it, please follow this recipe.
• pm-utils now has two new scripts to power down USB and various PCI devices in battery mode. A number of desktop packages were fixed to wake up less often. Both of these reduce power consumption and thus improve battery lifetime.
• resolvconf is now used to manage /etc/resolv.conf on all Ubuntu systems. You can learn more here
• Backports are now more easily accessible -- to enable users to more easily receive new versions of software, the Ubuntu Backports repository is now enabled by default. Packages from backports will not be installed by default — they must explicitly be selected in package management software. However, once installed, packages from backports will automatically be upgraded to newer versions.
• DVD Images -- the DVD images have been cleaned up significantly reducing their size to around 1.9GB to ease consumption. The remaining software remains available via download.

Ubuntu Kernel 3.2.0-37.37

By default, Ubuntu Studio 12.04.2 LTS will ship with a newer 3.2.0-37.37 kernel. This is based on the 3.2.37 Upstream Linux Kernel.

Upstart 1.5

Upstart has been updated to version 1.5. More details are available in the Upstart Technical Overview.

GNU Toolchain

Ubuntu 12.04 is distributed with a default toolchain that includes: GCC 4.6.3 (and changes from Linaro GCC 4.6-2012.02), binutils 2.22, eglibc 2.15, and Linaro gdb 7.4-2012.04.

Compared to the 11.10 release the toolchain did see only incremental changes and bug fixes; comparing to the 10.04 LTS release, GCC updates include

• Updated frontends for better standards support (Ada 2012, Objective-C 2.0, improved experimental support for the upcoming C++0x ISO C++ standard, Fortran 2003 and 2008 improvements, new Go frontend)
• Improved optimizations, including better inter-procedural optimizations, and link time optimization (LTO).

Further information can be found upstream (GCC-4.6, GCC-4.5, binutils, gas, ld, gdb).

Python Toolchain

Ubuntu 12.04 includes Python 2.7.3 and Python 3.2.3 Python 2.6 is no longer available for install.

There is expanded support for Python 3 in this release, with Python 3 ports of python-dbus, python-feedparser, germinate, lazr.ui, wadllib, python-defer, python-keyring, and python-qt4 now included, among others.

Java Toolchain

The default run time for Java is OpenJDK 6b24 (IcedTea 1.11.1). OpenJDK 7u3 (IcedTea 2.1) is available in the archive as well.

Installation

Overview

Preparing your computer for Ubuntu Studio is now much simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.

You can now reinstall or upgrade an existing copy of Ubuntu Studio with the Ubuntu Studio DVD installer, provided that your computer is connected to the Internet.

Download

Ubuntu Studio 12.04.2 images can be downloaded from:

• http://cdimage.ubuntu.com/ubuntustudio/releases/12.04.2/

http://cdimage.ubuntu.com/ubuntustudio/releases/12.04.2/

System Requirements

The minimum memory requirement for Ubuntu Studio 12.04.2 is 512 MB of memory. It is highly recommended that you have 2GB or more memory though so that the system will perform much better. More information about other recommended hardware on the new Ubuntu Studio website when it is released.

Upgrading

Upgrading from Ubuntu Studio 11.10

To upgrade from Ubuntu Studio 11.10, press Alt+F2 and type in "update-manager" (without the quotes) into the command box. Update Manager should open up and display following message: "New distribution release '12.04' is available. Click Upgrade and follow the on-screen instructions".

Upgrading from Ubuntu Studio 10.04 LTS to Ubuntu Studio 12.04 LTS

It is recommended that users perform a complete instal rather than upgrade from Ubuntu Studio 10.04 LTS due to extent of the changes, including desktop environments.

Upgrading from Other Releases

Users of other Ubuntu Studio releases need to upgrade first to 11.10, and then to 12.04.

For further information on upgrading to 11.10, please see the Ubuntu Oneiric upgrade instructions.

• Wubi (the Ubuntu installer for Windows) is not available as an option on the Ubuntu Desktop/DVD any more. Instead, it is now a separate download.
• Some Lenovo systems are unable to boot unsigned kernels in UEFI mode with Secure Boot enabled. (1087501)
• Sometimes enters failsafe-x mode when booting into Live Session in virtualbox with i386, yet booting from failsafe-x just freezes system. Workaround is to use amd64. (1124660)
• A bug in the firmware on certain Samsung laptop models leaves these machines at risk of being rendered inoperable ("bricked") when booted in UEFI mode. Steps have been taken with the kernel in 12.04.2 to mitigate this problem, but only a future firmware update from Samsung will resolve this issue with 100% reliability. It is therefore recommended that users boot their systems in CSM ("compatibility support module") mode to avoid this issue. (1040557)

Linux v3.2.14 Kernel

Ubuntu 12.04 LTS ships with an updated kernel moving from the mainline v3.0 series to the mainline v3.2 series. At release we are shipping with the Ubuntu 3.2.0-23.36 kernel which is based on the v3.2.14 upstream stable Linux kernel. The mainline v3.0 to v3.2 stable series update brings a number of new features. Some highlights include:

• ext4 gains support for larger base block sizes
• btrfs has more work addressing data integrity issues
• device mapper gains thin provisioning and recursive snapshots
• more work to improve performance under high writeback load
• networking improvements for congested networks
• ext3 moves to using filesystem barriers
• memory allocator improvements
• VFS scalability improvements
• a new iSCSI implementation
• software wait gains bad block management

Key changes in the Ubuntu kernel since the 3.0.0-12.20 Ubuntu kernel as shipped in the 11.10 Ubuntu release include:

• Rebase to upstream stable Linux kernel v3.2.14.
• The amd64 -generic and -server kernel flavors have been merged into a single -generic kernel flavor for Ubuntu 12.04. Given the few differences that existed between the two flavors, it only made sense to merge the two and reduce the overall maintenance burden over the life of this LTS release.
• Support for a new armhf kernel flavor has been introduced.
• The non-smp PowerPC kernel flavor has been removed. All hardware currently supported by the non-smp PowerPC kernel flavor should also be supported by the smp PowerPC kernel flavor.
• RC6 is enabled by default for Sandy Bridge systems. RC6 is a technology which allows the GPU to go into a very low power consumption state when the GPU is idle (down to 0W). It results in considerable power savings when this stage is activated. When comparing under idle loads with machine state where RC6 is disabled, improved power usage of around 40-60% has been witnessed.
• An improved set of jack detection patches has been backported from the upstream v3.3 Linux kernel.
• An updated AppArmor patch set has been included to better align with what is landing upstream.
• Applied and enabled the seccomp filters feature which uses the packet filtering machinery (BPF) to restrict access to system calls.
• A set of kexec fixes for arm from v3.3-rc1 has also been backported.
• We've also conducted an extensive review of Ubuntu kernel configs and made numerous config changes as a result.

Applications

Boot, Installation and Post-Installation

• [Dell Studio XPS 1340,Alienware m17x] Kernel panic and hang on boot due to the ite-cir driver. A patch has been sent upstream and a test kernel is referenced in the bug report. The fix will be immediately available as a kernel update from the precise-updates pocket following 12.04's release. (984387)
• When closing the lid on a Unibody Macbook, the screen interacts with the touchpad. This can cause spurious gestures and clicks, and potentially lead to corrupted input driver state if the laptop suspends. To work around the issue, remove and reload the kernel module after resume by running: $ sudo rmmod bcm5974 $ sudo modprobe bcm5974Note that this may disable some touchpad options, for example horizontal scrolling. These options can be re-enabled by visiting the Mouse and Touchpad settings. This is planned to be fixed in a post-release update (968845).
• Importing of existing Windows user accounts fails in some cases. (987902)

Ubuntu Studio 12.10の新機能

Ubuntu Studioはコンテンツ制作のためにデザインされた、Ubuntuのフレーバーです。

Ubuntu StudioはUSBスティックにインストール可能なDVDイメージとして提供され、多くの言語をデフォルトでサポートしています。

改善された点:

• ウェブページが新しくなりました。メインメニューの「Ubuntu Studio Information」から各項目をクリックすることで、このウェブページにジャンプします。
• メモリ使用量をよりわかりやすく表示するために、タスクマネージャーの代わりにシステムモニターを使うようになりました。
• ユーザーがメニューを変更することができるよう、メインメニューツールが追加されました。
• PlymouthのTextテーマを追加・修正しました。これまでグラフィックカードがうまく動かずにブートスプラッシュが表示されなかった環境でも、Ubuntu Studioが表示されるようになります。
• Ubuntu Studioが想定するワークフロー向けに、メニューアイテムにSoftware Centerを追加しました。
• 「アクセサリ」「教育」「インターネット」カテゴリー向けに、サブメニューアイコンを固定しました。

新しく追加されたソフトウェア:

• Xfceをバージョン4.10に更新しました。(Xubuntuをベースとします)
• カーネル（lowlatency）をバージョン3.5にしました。

Ubuntu Studioのアプリケーション

• オーディオ作成ツールをMedia Playbackカテゴリーから移動し、メニューに配置しました。
• MIDIルーターとMIDIツールをメニューに追加しました。
• オーディオワークフローの欠けていた機能をカバーするため、qmidirouteを追加しました。
• graphics seedにopen-clip-artを追加しました。
• ミキサーソフトウェアをMedia PlaybackカテゴリーからAudio Productionカテゴリーに移動しました。
• すべてにおいてNautilusがデフォルトのファイルマネージャーとなりました。

共通インフラストラクチャ

Secure Boot

Ubuntu 12.10 は、これまで盛んに議論されたUEFI Secure Bootをサポートする初めてのUbuntuです。UEFI Secure Bootは、システムの起動時においてコンピューター上で動作するソフトウェアを制御するための、標準的な手法です。Secure Bootをサポートすることは、クライアント環境向けWindows 8認定プログラムの必須要件のひとつです。

Ubuntuは、こうしたハードウェア上で「そのまま動く」ことに力を注いでいます。 しかしながら、リリースまでの時間の制約により、12.10世代でSecure Bootハードウェアで動作するフレーバーは次のものに限られています：

• Ubuntu desktop
• Ubuntu server
• Edubuntu

13.04では、これら以外の全フレーバーでも動作するでしょう。

Migration-supportの廃止

他のOS（訳注：Windowsや他のLinuxディストリビューション・以前にインストールされていたUbuntu）からUbuntuへのユーザーアカウントの移行を司るツール(migration-assistant) は、インストーラーから削除されました。

Linux kernel 3.5.5

Ubuntu 12.10 “Quantal Quetzal”リリース版には、3.5.0-17.28 Ubuntu Linux kernelが導入されます。これはv3.5.5 Linux kernelを元にしています。Ubuntu 12.04 LTSの3.2.0-23.36 Ubuntu Linux kernel（v3.2 Linux kernelベース）から更新されています。12.10世代のカーネルの注目すべき変更点は、次の通りです。

• i386 generic-paeフレーバーは、genericフレーバーで置き換えられます。
• virtualフレーバーは、genericフレーバーに統合されました。
• linux-metaパッケージが統一されました。
• “highbank” SoC（訳注：Calxeda EnergyCore）を搭載したARMサーバー用のカーネルフレーバーを追加しました。
• デフォルトのスケジューラーを、cfqからdeadlineに変更しました。
• 署名済みカーネルを生成するため、パッケージ方式を更新しました。

“highbank” SoC（訳注：Calxeda EnergyCore）を搭載したARMサーバー用のカーネルフレーバーを追加しました。

Python 3.2

Ubuntuのデスクトップ環境は、Python 2からPython 3への移行を進めています。デスクトップ環境に含まれる多くのPython製アプリケーションとそれらのライブラリは、多くがPython 3への対応を完了しています。たいていの場合、Python2用のものに相当するPython 3版ライブラリが準備されているはずです。すでに移植済みのアプリケーションは、Python 3上でのみ動作します。作業はUbuntu 13.04でも継続されます。

もしPython 2ベースのプログラムを開発している場合も、恐れる必要はありません。Python 2は、できる限り継続してサポートされます（python パッケージとして）。ただし、将来のバージョンのUbuntuでも利用できるようにするために、Python 3への移植を検討することをお勧めします。Python/3が移植作業の参考になるでしょう。

GNUツールチェイン

Ubuntu 12.10は、デフォルトのツールチェインに次の更新を加えています：GCC 4.7.2 (12.04 LTSではGCC 4.6)・binutilsとして2.23ブランチのスナップショット(12.04 LTSでは2.22)・eglibc 2.15・gdb 7.5。

より詳細な情報はupsteamのものを参照してください(GCC-4.7, gdb)。

Javaツールチェイン

Ubuntu 12.10は、OpenJDK7をデフォルトのJava実装として採用しています。これまでに比べて強化された性能と新機能、そして、他のJava7ベースの実装とのより高い互換性を備えています。

OpenJDK6は「deprecated」ステータスで、12.10ではuniverseに収録されている openjdk-6-* パッケージは、将来のUbuntuのリリースでは提供されなくなる予定です。

インストール

概要

Ubuntu Studioのインストールを、よりシンプルにする一方で、ディスク設定の選択肢を拡張しました。それぞれの操作の詳細説明を見直し、選択した操作の結果を、より分かりやすく把握できるようにしています。

Desktop CDから起動されるインストーラーは、インターネットに接続されていれば、既存のUbuntu Studio環境をアップグレードしたり、再インストールすることができます。

ダウンロード

Ubuntu Studio 12.10のイメージは、以下からダウンロードできます。

• http://cdimage.ubuntu.com/ubuntustudio/releases/12.10/release/ (UbuntuStudio)

http://cdimage.ubuntu.com/ubuntustudio/releases/12.10/release/ (UbuntuStudio)

システム要件

Ubuntu Studio 12.10に必要なメモリは768MBです。システムをより快適に動作させるには、2GB以上のメモリを搭載することを推奨します。その他の推奨ハードウェアに関する情報は、Ubuntu Studioウェブサイトで公開されます。

アップグレード

Ubuntu Studio 12.04からアップグレードするには、Alt+F2を押して、コマンドボックスで"update-manager"と入力してください（二重引用符は不要です）。アップデートマネージャーが起動して次のメッセージが表示されます: "新しいリリース '12.10' が利用可能です"。アップグレードをクリックし、画面上の指示に従ってください。

アップグレードには"photography"ならびに"publishing"メタパッケージが含まれないため、これらのパッケージが必要な場合は、アップグレード後に端末で"sudo apt-get install ubuntustudio-meta-photography ubuntustudio-meta-publishing"と入力して、手動でインストールを行なってください。

その他のリリースからのアップグレード

その他のUbuntu Studioのリリースを利用しているユーザーは、まず12.04にアップグレードした上で、12.10にアップグレードしてください。

11.10へのアップグレードに関する詳細情報は、このウェブページを参照して下さい。 Ubuntu Precise upgrade instructions

既知の問題

グラフィックスとディスプレイ

• プロプライエタリなドライバーは、software-properties-gtk（ソフトウェアソース）の"追加のドライバー"タブでインストールするようになりました。

アプリケーション

インストール

• Samsung製のノートPC（530U3C・NP700Z5C）において、UEFIモードに設定された状態でUbuntuのインストーラーを動作させると、ファームウェアのバグにより、結果としてマシンを起動不能に陥らせることがある、というレポートを受け取っています。この問題がUbuntu 12.10に真に再現するのか確認されるまでの間、該当するSamsung製ノートPCのユーザーがインストールを行う場合はUEFIモードを利用せず、レガシーBIOSモードに切り替えて利用してください。 (1040557)
• これまでDesktop/Alternateの2タイプに分かれていたインストールメディアを統合しました。これにより、Alternate CDが提供していた一部のインストールオプションが利用できなくなっています。DesktopイメージはAlternate CDを完全に置き換えるものではありません。 Alternate CDを用いて、LVMやディスク全体の暗号化を設定してインストールしていた場合、Desktopイメージを使うことで代替できます。 LTSPインストールを行う場合、Ubuntu Server 12.10のイメージを用います。LTSPパッケージをインストール後に追加します。12.04 LTSのメディアを継続して用いてインストールし、12.10へアップグレードすることで対応することもできます。 ソフトウェアRAIDを用いたインストールには、幾つかの選択肢があります。： mini.isoを用いてインストールし、'debian-installer'ディレクトリをミラーに配置して利用する。 Desktop CDを用いてインストールを完了した後、ディスクをRAID構成に変換する。 Ubuntu 12.04 LTSのAlternate CDを用いてインストールし、アップグレードする。
• Desktopイメージは、既存の暗号化（LUKS）ボリュームをアンロックすることができません。もし既存の暗号化ボリュームをパーティション構成時に必要とする場合は、「Ubuntuをインストールせずに試してみる」を起動画面で選択してライブセッションを開始し、暗号化ボリュームを開き（たとえば、UnityのLauncherからディスクを右クリックします）、パスワードを入力して暗号化を解除し、ウィンドウを閉じます。あらためて ubiquity を実行してインストーラーを実行してください。(1066480)
• ARM OMAP4マシンでは、インストール時に、真っ暗な画面で起動してしまう可能性があります。この場合もシステムは正常に起動しています。この現象に遭遇したら、一度別のTTYに切り替えてからTTY7に戻ってくる必要があります。Ctrl+Alt+F1の同時押しをしてから、Alt+F7を押すことで、グラフィックが復帰します。(1065902)
• Panda Board（ARM）を外部ストレージが接続されていない状態で利用すると、インストーラーのインターフェース部分が混乱した状態に陥り、まるでインストールに失敗したかのように見えます。Panda Boardを利用する場合、インストール時には外付けHDD等を接続しておくことをお勧めします。 (1053030)
• Macに外付けディスプレイを接続していると、インストール後、二度目の再起動から「can not run in framebuffer mode error」というエラーに遭遇します。(1066883)

Kernel

• Haswellプロセッサーの内蔵グラフィックのサポートは完全なものではありません。 (1066975)
• 一部のシステムでは、（ノートPCの）フタを開けた時に、サスペンド/レジュームに失敗した旨のkernelloopsメッセージが表示されます。 (1054732)
• AMDグラフィックチップを搭載した一部のASUSマシンでは、ディスプレイモードを変更するホットキーを押した際にWMIイベントとACPI割り込みが同時に送られることで、ディスプレイモードの変更が2回行われる結果となります。システム設定のディスプレイパネルを使ってディスプレイモードの変更を行う回避策があります。 (1052278)
• ASUS N53SNラップトップでは、コマンドラインでnoefiを指定しないとカーネルが起動できません。 (1053897)

Libvirt

• Windows VMはこれまで'vga'ビデオドライバーで動作していましたが、'cirrus'ビデオドライバーを使用する必要があります。

ツールチェイン

• Python 2.7.3には、Pythonのdictとsetの実装に影響するセキュリティ脆弱性への修正が含まれています。信頼できない入力をそのまま処理すると、計算リソースの過大消費やサービス停止状態(DoS)を引き起こすため、慎重に実装する必要があります。こうした攻撃への対処が必要な、たとえばCGIスクリプトのようなアプリケーションでは、この弱点を保護すために、"hash randomization"を明示的に有効にすることができます。この修正のもたらす実装の差により、古い2.7.xリリースで作成された「virtualenvs」は2.7.3で動作しないかもしれません。特にosモジュールはurandom関数が存在しないように見えるはずです。この問題は新しいPython 2.7.3のバージョンで、壊れたvirtualenvsを再作成することで解決することができます。詳細は http://bugs.python.org/issue13703 を確認してください。 (954595)

New Features in Ubuntu Studio 12.10

Ubuntu Studio is the Ubuntu flavour designed for content creation.

It's produced as a DVD image that can also be converted to an USB stick and includes support for most languages by default.

Improved Interface:

• A new web page is out. The help button on the main menu points there.
• Task Manager has been switched to System Monitor for better memory use display.
• A main menu tool has been added to setting to allow the user to change their menu.
• Add/fix text plymouth theme for those video cards that won't see graphics so it says Ubuntu studio.
• Set up Software Center menu items for our workflows.
• Fixed submenu icons for accessories, education and network.

New software include:

• Xfce updated to version 4.10 (based off of Xubuntu)
• Kernel (lowlatency) is now of version 3.5

Ubuntu Studio Applications

• The menu has been fixed moving audio production tools out of Media Playback.
• A MIDI router and MIDI tools menu have been added.
• Add qmidiroute to audio workflow to cover missing functionality
• Added open-clip-art package to graphics seed
• Move mixer applications from media playback menu to audio menu.
• Nautilus is default file manager for everything now

Common Infrastructure

Secure Boot

Ubuntu 12.10 is the first Ubuntu release to support UEFI Secure Boot, a standard for controlling what software can be run on a computer. Supporting Secure Boot, a part of the Windows 8 certification requirements for client systems, ensures that Ubuntu will continue to provide an "it just works" experience on new hardware.

Due to time pressures, only some flavors released with 12.10 will install and boot on Secure Boot hardware:

• Ubuntu desktop
• Ubuntu server
• Edubuntu

We expect to enable all other flavors in 13.04.

Migration-support deprecated

The tool responsible for migrating user accounts from other operating systems to Ubuntu (migration-assistant) has been removed from the installer.

Linux kernel 3.5.5

The Ubuntu 12.10 Quantal Quetzal release includes the 3.5.0-17.28 Ubuntu Linux kernel which was based on the v3.5.5 upstream Linux kernel. This is an update from the 3.2.0-23.36 Ubuntu Linux kernel which shipped in Ubuntu 12.04 LTS Precise Pangolin and was based on the v3.2 upstream Linux kernel. Other notable changes with the Ubuntu 12.10 Quantal Quetzal kernel include:

• Transitioning of the i386 generic-pae flavor to become the generic flavor offering
• Collapsing of the virtual flavor back into the generic flavor
• Homogenizing the entire linux-meta package
• Arrival of a new highbank arm server kernel flavor
• Changing of the default scheduler from cfq to deadline
• Packaging updates for signed kernels

Python 3.2

The Ubuntu desktop has begun migrating from Python 2 to Python 3. Most Python applications included in the desktop and their dependent libraries have been ported to Python 3. In most cases, Python 3 versions of libraries are available alongside their Python 2 counterparts. Ported applications will only run with Python 3. Work will continue in Ubuntu 13.04.

If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. Python/3 has some advice and resources on this.

GNU Toolchain

Ubuntu 12.10 is distributed with an updated default toolchain that includes: GCC 4.7.2 (was GCC 4.6 in 12.04 LTS), a binutils snapshot from the 2.23 branch (was 2.22 in 12.04 LTS), eglibc 2.15, and gdb 7.5.

Further information can be found upstream (GCC-4.7, gdb).

Java Toolchain

Ubuntu 12.10 ships OpenJDK7 as the default Java implementation. This brings improved performance, new features and better compatibility with other Java 7 implementations.

Use of the OpenJDK6 is now deprecated and the openjdk-6-* packages in universe for Ubuntu 12.10 will not be provided in future releases of Ubuntu.

Installation

Overview

Preparing your computer for Ubuntu Studio is now simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.

You can now reinstall or upgrade an existing copy of Ubuntu Studio with the Ubuntu Studio DVD installer, provided that your computer is connected to the Internet.

System Requirements

The minimum memory requirement for Ubuntu Studio 12.10 is 768 MB of memory. It is highly recommended that you have 2GB or more memory though so that the system will perform much better. More information about other recommended hardware on the new Ubuntu Studio website when it is released.

Upgrading

Upgrading from Ubuntu Studio 12.04

To upgrade from Ubuntu Studio 12.04, press Alt+F2 and type in "update-manager" (without the quotes) into the command box. Update Manager should open up and display following message: "New distribution release '12.10' is available. Click Upgrade and follow the on-screen instructions".

Since the upgrade does not include the new "photography" and "publishing" metas, so if you want the photography and publishing packages in your upgrade, please install them manually after upgrade by typing "sudo apt-get install ubuntustudio-meta-photography ubuntustudio-meta-publishing" in your terminal.

Upgrading from Other Releases

Users of other Ubuntu Studio releases need to upgrade first to 12.04, and then to 12.10.

For further information on upgrading to 11.10, please see the Ubuntu Precise upgrade instructions.

Known Issues

Graphics and Display

• Proprietary drivers are now installed using software-properties-gtk (Software Sources), under the tab "Additional Drivers".

Applications

Installation

• A bug may cause a failure in memtest test #7. See this memtest86+ bug
• Booting the Ubuntu installer in UEFI mode from a USB disk on certain Samsung laptops (530U3C, NP700Z5C) may trigger a firmware bug that renders the machine unbootable. Users are advised to use caution when installing on Samsung laptops and ensure that they are configured for legacy BIOS mode, not UEFI mode. (1040557)
• The consolidation of desktop installation media into a single image means that some installation options that were previously available on the alternate CD have no direct replacement on the desktop image. Users who were installing using the alternate CD to install with LVM or full-disk encryption can now use the desktop image for this. To install LTSP, please install using the Ubuntu Server 12.10 image, then add ltsp after installation. You can also continue to install with Ubuntu 12.04 LTS media and upgrade to 12.10 from there. There are several options for installing using software RAID. You can: install using the mini.iso, distributed from the 'debian-installer' directory on the mirrors; install using the desktop CD and migrate the disks to RAID post-install; install with the Ubuntu 12.04 LTS alternate CD and upgrade.
• The desktop image installer cannot unlock existing encrypted (LUKS) volumes. If you need to make use of existing encrypted volumes during partitioning, then use the "Try Ubuntu without installing" boot option to start a live session, open the encrypted volumes (for example, by clicking on their icons in the Unity launcher), enter your password when prompted to unlock them, close them again, and run ubiquity to start the installer. (1066480)
• ARM OMAP4 machines will sometimes boot to a black screen during installation. It's likely that the system has booted fine, but you will need to switch to another tty then back to tty7 (Ctrl+Alt+F1 and then Alt+F7) to get graphics. (1065902)
• On ARM Panda boards with no external storage attached, the installer interface will be confusing and installation is likely to fail. We strongly recommend attaching an external hard disk when installing on Panda boards. (1053030)
• On a mac with an external display can not run in framebuffer mode error occurs on the 2nd reboot onwards. (1066883)

Kernel

• Haswell processor graphics is not fully supported. (1066975)
• On some systems, when opening lid, there is a kerneloops with a suspend/resume failure message seen. (1054732)
• On certain ASUS machines with AMD graphic chips, a WMI event and ACPI interrupt are sent at the same time when hitting the hotkey to change display mode, resulting in the display mode being changed twice in succession. Users can work around this using the Displays panel in System Settings for changing display modes. (1052278)
• On ASUS N53SN laptops, the kernel does not boot without noefi on commandline. (1053897)

Networking

• In order to improve compatibility with other local nameserver packages, NetworkManager now assigns IP address 127.0.1.1 to the local nameserver process that it controls instead of 127.0.0.1. If the system's /etc/resolv.conf is absent or is a static file instead of the symbolic link to ../run/resolvconf/resolv.conf installed by default then this static file will have to be updated by the administrator in order to continue using the NetworkManager-controlled nameserver.

Libvirt

• Windows vms which previously worked with 'vga' video now need 'cirrus' video.

Toolchain

• Python 2.7.3 includes a fix for a security vulnerability affecting Python's dict and set implementations. Carefully crafted, untrusted input could lead to extremely long computation times and denials of service. Although disabled by default, vulnerable applications such as CGI scripts can explicitly enable "hash randomization" to prevent this exploit. Due to implementation details of this fix, virtualenvs created with older 2.7.x releases may not work with 2.7.3. Specifically, the os module may not appear to have a urandom function. This problem can be solved by recreating the broken virtualenvs with the newer Python 2.7.3 version. See http://bugs.python.org/issue13703 for full details. (954595)

VMware Player

• Installing either version 4 or 5 of VMware Player on Ubuntu 12.10 will trigger a crash report regarding lsb_release, because the lsb_release command uses Python 3 but the VMware installation environment overrides the Python settings to point to a bundled version of Python 2. (938869) It is unknown what impact this has on VMware Player at runtime.

Ubuntu Studio 12.10の新機能

Ubuntu Studioはコンテンツ制作のためにデザインされた、Ubuntuのフレーバーです。

Ubuntu StudioはUSBスティックにインストール可能なDVDイメージとして提供され、多くの言語をデフォルトでサポートしています。

改善された点:

• ウェブページが新しくなりました。メインメニューの「Ubuntu Studio Information」から各項目をクリックすることで、このウェブページにジャンプします。
• メモリ使用量をよりわかりやすく表示するために、タスクマネージャーの代わりにシステムモニターを使うようになりました。
• ユーザーがメニューを変更することができるよう、メインメニューツールが追加されました。
• PlymouthのTextテーマを追加・修正しました。これまでグラフィックカードがうまく動かずにブートスプラッシュが表示されなかった環境でも、Ubuntu Studioが表示されるようになります。
• Ubuntu Studioが想定するワークフロー向けに、メニューアイテムにSoftware Centerを追加しました。
• 「アクセサリ」「教育」「インターネット」カテゴリー向けに、サブメニューアイコンを固定しました。

新しく追加されたソフトウェア:

• Xfceをバージョン4.10に更新しました。(Xubuntuをベースとします)
• カーネル（lowlatency）をバージョン3.5にしました。

Ubuntu Studioのアプリケーション

• オーディオ作成ツールをMedia Playbackカテゴリーから移動し、メニューに配置しました。
• MIDIルーターとMIDIツールをメニューに追加しました。
• オーディオワークフローの欠けていた機能をカバーするため、qmidirouteを追加しました。
• graphics seedにopen-clip-artを追加しました。
• ミキサーソフトウェアをMedia PlaybackカテゴリーからAudio Productionカテゴリーに移動しました。
• すべてにおいてNautilusがデフォルトのファイルマネージャーとなりました。

共通インフラストラクチャ

Secure Boot

Ubuntu 12.10 は、これまで盛んに議論されたUEFI Secure Bootをサポートする初めてのUbuntuです。UEFI Secure Bootは、システムの起動時においてコンピューター上で動作するソフトウェアを制御するための、標準的な手法です。Secure Bootをサポートすることは、クライアント環境向けWindows 8認定プログラムの必須要件のひとつです。

Ubuntuは、こうしたハードウェア上で「そのまま動く」ことに力を注いでいます。 しかしながら、リリースまでの時間の制約により、12.10世代でSecure Bootハードウェアで動作するフレーバーは次のものに限られています：

• Ubuntu desktop
• Ubuntu server
• Edubuntu

13.04では、これら以外の全フレーバーでも動作するでしょう。

Migration-supportの廃止

他のOS（訳注：Windowsや他のLinuxディストリビューション・以前にインストールされていたUbuntu）からUbuntuへのユーザーアカウントの移行を司るツール(migration-assistant) は、インストーラーから削除されました。

Linux kernel 3.5.5

Ubuntu 12.10 “Quantal Quetzal”リリース版には、3.5.0-17.28 Ubuntu Linux kernelが導入されます。これはv3.5.5 Linux kernelを元にしています。Ubuntu 12.04 LTSの3.2.0-23.36 Ubuntu Linux kernel（v3.2 Linux kernelベース）から更新されています。12.10世代のカーネルの注目すべき変更点は、次の通りです。

• i386 generic-paeフレーバーは、genericフレーバーで置き換えられます。
• virtualフレーバーは、genericフレーバーに統合されました。
• linux-metaパッケージが統一されました。
• “highbank” SoC（訳注：Calxeda EnergyCore）を搭載したARMサーバー用のカーネルフレーバーを追加しました。
• デフォルトのスケジューラーを、cfqからdeadlineに変更しました。
• 署名済みカーネルを生成するため、パッケージ方式を更新しました。

“highbank” SoC（訳注：Calxeda EnergyCore）を搭載したARMサーバー用のカーネルフレーバーを追加しました。

Python 3.2

Ubuntuのデスクトップ環境は、Python 2からPython 3への移行を進めています。デスクトップ環境に含まれる多くのPython製アプリケーションとそれらのライブラリは、多くがPython 3への対応を完了しています。たいていの場合、Python2用のものに相当するPython 3版ライブラリが準備されているはずです。すでに移植済みのアプリケーションは、Python 3上でのみ動作します。作業はUbuntu 13.04でも継続されます。

もしPython 2ベースのプログラムを開発している場合も、恐れる必要はありません。Python 2は、できる限り継続してサポートされます（python パッケージとして）。ただし、将来のバージョンのUbuntuでも利用できるようにするために、Python 3への移植を検討することをお勧めします。Python/3が移植作業の参考になるでしょう。

GNUツールチェイン

Ubuntu 12.10は、デフォルトのツールチェインに次の更新を加えています：GCC 4.7.2 (12.04 LTSではGCC 4.6)・binutilsとして2.23ブランチのスナップショット(12.04 LTSでは2.22)・eglibc 2.15・gdb 7.5。

より詳細な情報はupsteamのものを参照してください(GCC-4.7, gdb)。

Javaツールチェイン

Ubuntu 12.10は、OpenJDK7をデフォルトのJava実装として採用しています。これまでに比べて強化された性能と新機能、そして、他のJava7ベースの実装とのより高い互換性を備えています。

OpenJDK6は「deprecated」ステータスで、12.10ではuniverseに収録されている openjdk-6-* パッケージは、将来のUbuntuのリリースでは提供されなくなる予定です。

インストール

概要

Ubuntu Studioのインストールを、よりシンプルにする一方で、ディスク設定の選択肢を拡張しました。それぞれの操作の詳細説明を見直し、選択した操作の結果を、より分かりやすく把握できるようにしています。

Desktop CDから起動されるインストーラーは、インターネットに接続されていれば、既存のUbuntu Studio環境をアップグレードしたり、再インストールすることができます。

ダウンロード

Ubuntu Studio 12.10のイメージは、以下からダウンロードできます。

• http://cdimage.ubuntu.com/ubuntustudio/releases/12.10/release/ (UbuntuStudio)

http://cdimage.ubuntu.com/ubuntustudio/releases/12.10/release/ (UbuntuStudio)

システム要件

Ubuntu Studio 12.10に必要なメモリは768MBです。システムをより快適に動作させるには、2GB以上のメモリを搭載することを推奨します。その他の推奨ハードウェアに関する情報は、Ubuntu Studioウェブサイトで公開されます。

アップグレード

Ubuntu Studio 12.04からアップグレードするには、Alt+F2を押して、コマンドボックスで"update-manager"と入力してください（二重引用符は不要です）。アップデートマネージャーが起動して次のメッセージが表示されます: "新しいリリース '12.10' が利用可能です"。アップグレードをクリックし、画面上の指示に従ってください。

アップグレードには"photography"ならびに"publishing"メタパッケージが含まれないため、これらのパッケージが必要な場合は、アップグレード後に端末で"sudo apt-get install ubuntustudio-meta-photography ubuntustudio-meta-publishing"と入力して、手動でインストールを行なってください。

その他のリリースからのアップグレード

その他のUbuntu Studioのリリースを利用しているユーザーは、まず12.04にアップグレードした上で、12.10にアップグレードしてください。

11.10へのアップグレードに関する詳細情報は、このウェブページを参照して下さい。 Ubuntu Precise upgrade instructions

既知の問題

グラフィックスとディスプレイ

• プロプライエタリなドライバーは、software-properties-gtk（ソフトウェアソース）の"追加のドライバー"タブでインストールするようになりました。

アプリケーション

インストール

• Samsung製のノートPC（530U3C・NP700Z5C）において、UEFIモードに設定された状態でUbuntuのインストーラーを動作させると、ファームウェアのバグにより、結果としてマシンを起動不能に陥らせることがある、というレポートを受け取っています。この問題がUbuntu 12.10に真に再現するのか確認されるまでの間、該当するSamsung製ノートPCのユーザーがインストールを行う場合はUEFIモードを利用せず、レガシーBIOSモードに切り替えて利用してください。 (1040557)
• これまでDesktop/Alternateの2タイプに分かれていたインストールメディアを統合しました。これにより、Alternate CDが提供していた一部のインストールオプションが利用できなくなっています。DesktopイメージはAlternate CDを完全に置き換えるものではありません。 Alternate CDを用いて、LVMやディスク全体の暗号化を設定してインストールしていた場合、Desktopイメージを使うことで代替できます。 LTSPインストールを行う場合、Ubuntu Server 12.10のイメージを用います。LTSPパッケージをインストール後に追加します。12.04 LTSのメディアを継続して用いてインストールし、12.10へアップグレードすることで対応することもできます。 ソフトウェアRAIDを用いたインストールには、幾つかの選択肢があります。： mini.isoを用いてインストールし、'debian-installer'ディレクトリをミラーに配置して利用する。 Desktop CDを用いてインストールを完了した後、ディスクをRAID構成に変換する。 Ubuntu 12.04 LTSのAlternate CDを用いてインストールし、アップグレードする。
• Desktopイメージは、既存の暗号化（LUKS）ボリュームをアンロックすることができません。もし既存の暗号化ボリュームをパーティション構成時に必要とする場合は、「Ubuntuをインストールせずに試してみる」を起動画面で選択してライブセッションを開始し、暗号化ボリュームを開き（たとえば、UnityのLauncherからディスクを右クリックします）、パスワードを入力して暗号化を解除し、ウィンドウを閉じます。あらためて ubiquity を実行してインストーラーを実行してください。(1066480)
• ARM OMAP4マシンでは、インストール時に、真っ暗な画面で起動してしまう可能性があります。この場合もシステムは正常に起動しています。この現象に遭遇したら、一度別のTTYに切り替えてからTTY7に戻ってくる必要があります。Ctrl+Alt+F1の同時押しをしてから、Alt+F7を押すことで、グラフィックが復帰します。(1065902)
• Panda Board（ARM）を外部ストレージが接続されていない状態で利用すると、インストーラーのインターフェース部分が混乱した状態に陥り、まるでインストールに失敗したかのように見えます。Panda Boardを利用する場合、インストール時には外付けHDD等を接続しておくことをお勧めします。 (1053030)
• Macに外付けディスプレイを接続していると、インストール後、二度目の再起動から「can not run in framebuffer mode error」というエラーに遭遇します。(1066883)

ネットワーク

• 他のローカルで動作するネームサーバーパッケージとの互換性を確保するため、ネットワークマネージャーはこれまでの127.0.0.1を割り当てていたローカルネームサーバー用IPアドレスを127.0.1.1に割り当てるようになりました。システムの/etc/resolv.confが存在しない、またはデフォルトでインストールされる../run/resolvconf/resolv.confへのシンボリックリンクではなく静的ファイルだった場合、ネットワークマネージャー管理のネームサーバーを利用し続けるには、この静的ファイルを管理者に更新してもらう必要があります。

Libvirt

• Windows VMはこれまで'vga'ビデオドライバーで動作していましたが、'cirrus'ビデオドライバーを使用する必要があります。

ツールチェイン

• Python 2.7.3には、Pythonのdictとsetの実装に影響するセキュリティ脆弱性への修正が含まれています。信頼できない入力をそのまま処理すると、計算リソースの過大消費やサービス停止状態(DoS)を引き起こすため、慎重に実装する必要があります。こうした攻撃への対処が必要な、たとえばCGIスクリプトのようなアプリケーションでは、この弱点を保護すために、"hash randomization"を明示的に有効にすることができます。この修正のもたらす実装の差により、古い2.7.xリリースで作成された「virtualenvs」は2.7.3で動作しないかもしれません。特にosモジュールはurandom関数が存在しないように見えるはずです。この問題は新しいPython 2.7.3のバージョンで、壊れたvirtualenvsを再作成することで解決することができます。詳細は http://bugs.python.org/issue13703 を確認してください。 (954595)
