Here’s a switcher story of a different color: from the Mac, to Linux. It’s one thing to talk about operating systems and free software in theory, or to hear from died-in-the-wool advocates of their platform of choice. In this case, we turn to Kim Cascone, an experienced and gifted musician and composer with an impressive resume of releases and a rich sens of sound. This isn’t someone advocating any platform over another: it’s an on-the-ground, in-the-trenches, real-world example of how Kim made this set of tools work in his music, in the studio and on tour. A particular thanks, as he’s given me some new ideas for how to work with Audacity and Baudline. Kim puts his current setup in the context of decades of computer work. Even if you’re not ready to leave Mac (or Windows) just yet, Kim’s workflow here could help if you’re looking to make a Linux netbook or laptop more productive in your existing rig.

Stay tuned, as I’ll have some other stories on how to make your Linux music workflow effective creatively, particularly in regards to leaping over some of the setup hurdles Kim describes. -PK

Historical Evolution

I’ve been working with computers since the 1970s. Inspired by the work of composer David Behrman, I taught myself assembly language and programmed a simple digital sequencer on a KIM-1, single-board microcomputer, controlling an Aries modular synthesizer I had built. I discovered a then-new magazine called Computer Music Journal at the local computer shop and bought every copy I could get my hands on. (I still have them, too.) Later, I helped a friend’s father, an executive at IBM, unpack and set up the first personal computer IBM made. The manuals alone took up two or three feet of bookshelf space.

Fast-forward through a couple of decades of owning Commodore 64s, Apple computers, and PCs. In 1997, I purchased my first laptop: a woefully-underpowered Compaq Presario. It wasn’t fast enough for real-time audio, so I had to render sound files to hard disk using the audio programming language Csound. I created many of the sounds this way for my CD ‘blueCube( )’. But the capacity to work anywhere was enough for me to give up ever owning another desktop computer.

Frustrated with the ‘code-compile-listen’ process of working with Csound and wanting to work in real-time, I switched to the graphical multi-media programming language Max/MSP, which necessitated a move back to Apple hardware, so I bought a PowerBook. Having Max/MSP running on a laptop was the perfect environment for me. I could build the tools I needed whenever an idea presented itself. The computer functioned as both sound design studio and stage instrument. I worked this way for ten years, faithfully following the upgrade path set forth by Apple and the various developers of the software I used. Continually upgrading required a substantial financial commitment on my part.

Apple Seeds of Discontent

When I’m on the road, I use my laptop as a music studio, performance instrument, and administration office. I don’t like surprises on the road. Having a computer fail means a loss of income, and makes for an embarrassing moment if the failure happens during a performance. If watching laptop music bores some people, watching a musician reboot is even worse. So to be safe, I stress-test all new hardware or software in my studio for at least a month before I take it on the road. Max/MSP patches run for hours, software is used for weeks, and hardware is left on for days at a time to help induce failure before I leave home. But as fate would have it, an iBook I was touring with died a few years ago. I brought the laptop into an Apple repair shop in Berlin, where a technician diagnosed the problem as a faulty logic board. The failure rate on logic boards was high for that model of iBook, and in response to public pressure, Apple instituted a logic board replacement program. Luckily, my laptop qualified and the logic board was replaced for free. But the failure and ongoing buggy behavior impacted my work schedule and added to the stress of touring.

I’ve now replaced logic boards on three computers; the other two I paid for out of pocket. The out-of-warranty cost of replacing a logic board on an Apple laptop is around six hundred dollars — cheaper than buying a brand new laptop, but still significant.

If you make your living with applications that run on OS X, there are no options if a laptop fails. You either repair expensive Apple hardware or buy new expensive Apple hardware. This is called ‘vendor lock-in.’

Then, during my 2009 spring tour, my PowerBook G4 exhibited signs of age, with missing keystrokes, intermittent backlighting, the failure of a RAM slot, and reduced performance. As an alternative to repairing the PowerBook, I investigated what a new MacBook Pro and upgrades for all my software would cost. A quick back-of-a-napkin estimate came to approximately $3,000, not including the time it would take tweaking and testing to make it work for the tour. If the netbook revolution hadn’t come along and spawn a price-wars on laptops, I might have proceeded to increase my credit card debt. But as a wise uncle once advised, “you invest either your time or your money; never both.”

Meeting Ubuntu

I had tried Linux in 2005 on PowerPC-based Mac laptops, though at the time I couldn’t get audio working, even after extensive tweaking. But I had kept an eye on Ubuntu ever since. After considering MacBook Pro prices, I checked out the new netbooks coming to market and picked up a refurbished Dell Inspiron Mini 9 with Ubuntu pre-installed.

I loaded up my Dell with all a selection of Linux audio applications and brought it with me on tour as an emergency backup to my tottering PowerBook. The Mini 9 could play back four tracks of 24-bit/96 kHz audio with effects – not bad for a netbook. The solution to my financial constraint became clear, and I bought a refurbished Dell Studio 15, installed Ubuntu on it, and set it up for sound production and business administration. The total cost was around $600 for the laptop plus a donation to a software developer — a far cry from the $3000.00 price tag and weeks of my time it would have cost me to stay locked-in to Apple. After a couple of months of solid use, I have had no problems with my laptop or Ubuntu. Both have performed flawlessly, remaining stable and reliable.

Getting Past Ubuntu Audio Complexities

There are a few differences between how audio works on Mac OS X and how it works on Ubuntu Linux. OS X uses the Core Audio and Core MIDI frameworks for audio and MIDI services, respectively. All applications requiring audio services on OS X talk to Core Audio, which mixes and routes multiple audio streams to the desired locations. Core Audio is simple, monolithic, and easy to set up, and all the end-user controls are accessible from one panel. You can even create a single aggregate device from multiple sound cards if you need more inputs or outputs than one sound card can supply. To Apple’s credit, Core Audio and the applications that make use of it are the reason why you see so many laptop musicians seated behind glowing Apple logos on stage.

On Ubuntu, audio is a rather different story. Apple’s slogan ‘Think Different’ would be good advice for musicians encountering Ubuntu’s audio setup for the first time. Audio in Ubuntu can appear at first to be a confusing jumble of servers, layers, services, and terminology. Go to System->Preferences->Sound, click on the Devices tab, and check out the pulldown menu next to ‘Sound Events’ at the top of the panel. You will see various acronyms, possibly including cryptic-looking technologies like OSS, ESD, ALSA, JACK, and Pulse Audio. These acronyms represent a byzantine tangle of conflicting technologies that over time, and due to political reasons or backwards compatibility, have ended up cohabiting with one another. ‘Frankenstein’ might be an accurate metaphor here.

Thankfully, there is a simpler way, which is the combination of ALSA [a high-performance, kernel-level audio and MIDI system] and JACK [a system for creating low-latency audio, MIDI, and sync connections between applications and computers]. The battle-scarred among us have learned to ignore all the other audio cruft bolted on to Ubuntu and just use ALSA and JACK. One can think of the ALSA/JACK stack, the heart of most pro Linux studios, as the Core Audio of Linux and in my opinion Jack should be the first thing installed on any musicians laptop. I’d go so far as to suggest placing it in the Startup Applications so it’s always running.

The ALSA/JACK combination is a little more complex to set up and tweak than Apple’s Core Audio, but there’s a lot of good information online. [Ed.: ALSA, JACK, and the real-time Linux kernel also have some advantages over Mac OS X that can be worth the effort. While JACK has been ported to Mac, Linux has more JACK-aware tools, which is necessary for transport sync. Just as importantly, once configured, you can build rigs with Linux that have greater low-latency performance than may be practical on Mac or Windows. In other words, while it may require an investment of time, it can be both free and better! -PK]

Workflow

Over the past ten years, I’ve developed a workflow that has worked well in the studio and on the road. Since I created most of my tools in Max/MSP, they could shape-shift to fit any musical task I encountered. A sound mangling tool I’d written for studio use, for instance, I could then adapt for a performance with Tony Conrad. I modified parts of my performance patch for sound installations. This environment served me well over the years – until recently, when my aesthetic focus changed from using randomness in my work to taking a more deterministic approach. This happened to coincide with my change of operating systems.

I do a lot of location recording while on tour. My rig consists of an Olympus LS-10 digital recorder and an Audio Technica AT-822 single-point stereo microphone. I record at 96kHz/24-bit to a 16GB SDHC card in the LS-10. When I want to audition sound files in the field, I use my netbook’s SDHC reader, renaming sound files directly on the card. I can look at some of the files in Baudline if I need to check for low-frequency rumble or technical anomalies. I have come to use Baudline on a daily basis.

Back in the studio, using the sound editing program Audacity, I remove voice slates, trim heads and tails, adjust gain and EQ as needed, then save them to a project folder. And because I don’t like surprises in the studio, either, this folder gets backed up onto a remote network drive as well as a local USB drive.

Building my sound library takes weeks or months. During this time, I start filling a notebook with ideas, drawings, plans and marginalia, from which a score emerges. I import all my project sound files into the open-source Digital Audio Workstation Ardour, arranging them to loosely resemble the score in my notebook. Once my Ardour session is set up, I move sounds around, try different effects, create new textures by layering, then render and re-import sub-mixes until the piece starts to take shape. I use a KORG nanoKONTROL as a mixing surface. I assign faders, pans and switches assigned to the DAW allowing me to quickly play around with different mix ideas.

Once the piece sounds finished, I mix down to a stereo .WAV file at 24-bit/44.1kHz, without using compression or EQ on the mix bus. Tip: mastering engineers really appreciate getting a raw 24-bit master that hasn’t been fiddled around with by the musician. For performances, I also use Ardour and the nanoKONTROL to do an acousmatic presentation. This version of the Ardour session will have compression and/or EQ on the mix bus, since I want the material to sound more polished. As a side note: I am looking into using the mastering tool JAMin [JACK Audio Mastering Interface] for this purpose in the future.

Sayonara, Apple

After ten years of working on Apple laptops, I’ve left the fold. Not only was the expense of owning and maintaining Apple hardware a key factor in my switch, but the operating system had become a frustration to me. Details like not having a tree-view in the right hand panel of the Finder window slowed me down. Ubuntu, on the other hand, feels more like an operating system made for grown-ups. And what’s especially nice is that Ubuntu scales nicely to the expertise of the user. Your cousin the computer geek or your Grandma can install and use Ubuntu and get as deep as they like. Combine this with the recent rash of cheap, powerful laptops, and Ubuntu’s market share is bound to grow.

A Request

It’s important that kernel and audio application developers (1) ensure all audio creation software has support for JACK, (2) improve and update tools for JACK to make it easy for musicians to install, configure, and use, (3) ship distros with the realtime kernel already tested and configured for use, (4) to integrate the real-time kernel patches into the mainline kernel. [Ed.: On each of these points, distributions and kernel builds are steadily improving, partly thanks to feedback from communities like the music production community. The realtime kernel likely won't be the default, mainline kernel, but it's important to have well-maintained optional packages at the very least. That doesn't mean you have to wait for improvements to happen, though, and in future articles I'll talk a bit about how you can configure your system now to take advantage of this functionality. -PK]

Most importantly, consider paying a subscription to support developers of JACK and your favorite Linux audio software, or, if you can write code, proofread text, write a manual, do a translation, contribute graphic design, or create content; please help by contributing something to the development of the software you use.

I would like to thank Ken Restivo, Mike Rooke, Paul Davis, Philip DeTullio, Jörn Nettingsmeier and Matt Griffen at Canonical Ltd. for advice and inspiration in the writing of this article.

Corrections / clarifications:

Ed.: I originally claimed that JACK Transport sync is not possible on the Mac OS X port of JACK. As kindly pointed out by a reader, this is not correct. JACK Transport-aware applications on the Mac will work.

Secondly, Kim argued that you could pull out a drive without having to go to a lot of trouble unmounting it first. At least one commenter argues that risks data loss, and given that users may be using something like FUSE to access foreign file systems like NTFS or the Mac’s own HFS+, I don’t yet know what the exact details will be. As I said in comments, however, Nautilus and the command line eject function for me are quicker and more effective than similar unmounting on Windows and Mac, so I still notch this one for Linux. -PK

Laptops for music are nothing new. But better versions of Linux make no-hassle music production easier and more powerful – and new netbooks make it cheap and ultra-portable, too, for times when even that 15” laptop feels clunky. Netbooks aren’t for everyone, and I imagine some people will miss Windows and Mac OS, even with better compatibility and powerful features on Linux. But if you are looking for an additional, more mobile machine, the combination is definitely worth a look.

A significant revision to the one netbook customized for Linux music has just become available today – you read about it here first.

The elements of Linux-based music making have reached a nice convergence with the release of Ubuntu 9.04 – the combination of a polished, mature Linux distribution with a newly-updated real-time kernel for low-latency audio is looking especially potent. At the same time, the increasingly-popular netbook has also improved in the latest generation. Ronald Stewart of Indamixx, a custom Linux mobile computer builder and OS packager, writes to brag about his latest generation. And he’s even found a way to do mobile music in his vehicle. (Let’s hope traffic in the LA area isn’t so bad that you’re actually adjusting beats in a tracker on the road, however.)

Indamixx has three products here, one software and two hardware:

• The original Indamixx portable studio is built on Samsung’s OLPC platform. I reviewed it for Keyboard Magazine. It’s really, really ultra-portable, and is something of a technological achievement. But most of us would prefer something more like a laptop, with a little more power and a conventional keyboard/mouse. Good news:
• The Indamixx Laptop is a netbook, with more power and more conventional uses – but still pre-tuned to run Linux audio, and still ultra-portable.
• Transmission is Indamixx’s custom Linux distribution, built on Studio64 and Ubuntu 9.04, but with extra tools to make hosting Windows VSTs and importing your existing projects easier.

Transmission should be available soon for people who already own a netbook. You get more than you get with a stock Ubuntu install. For instance, the included commercial product ardourXchange allows you to import AAF files from Pro Tools, Logic, and the like into the open source Ardour DAW.

It also ships with the commercial app energyXT. I think it’d worth buying a copy of the superb, modern tracker Renoise, which has excellent Linux support. Renoise also got a significant update, now in beta, which I’ll talk about by next week. Ardour 3.0 is expected to be a major update, as well, with support for MIDI and VSTs – that could be a game-changer when it happens, so stay tuned.

The laptop is what especially intrigues me. Linux is great, but it is nice having a configuration that’s static, because it helps navigate around potential compatibility issues with specific hardware specs. (That’s a problem we see regularly on Windows, too, and even occasionally – as with a specific wifi bug on an early build of Leopard – on the Mac.)

Indamixx has a special version of the MSI Wind that comes pre-optimized for Indamixx. Ronald describes the newly-updated Indamixx Laptop specs. (We saw the laptop here on CDM first in November, but this is a significant upgrade from that model):

• Transmission OS 3.0, which thanks to the new kernel and Ubuntu 9.04 has various enhancements and does a much better job of handling network 3G / HDSPA cards for mobile connectivity
• A 2.0 GHz CPU – the only overclocking-capable netbook
• 2 GB pre-installed RAM from the factory, which (sadly) is rarity in netbooks
• 160 GB HDD (doubled from the previous model)
• 10.2” widescreen display, up from the somewhat-cramped 8.9” on the previous model
• Large-style keyboard layout, roughly 95% of the size of a regular keyboard
• 2.6 pounds, up to 4 hours battery life

The 2.6.29.1 kernel is new to Ubuntu 9.04. Combined with the real-time JACK, you get excellent low-latency performance. (Incidentally, I’ve found that also applies to Windows software running in Linux under the Windows compatibility environment WINE – I’ve had success with NI’s Reaktor. Not officially supported, but quite a lot of fun. Ronald reports at least one user running Guitar Rig 2, as well.)

Indamixx also throws in a carrying case and free FedEx shipping.

I’ll be installing Ubuntu 9.04 on my main PC laptop soon, and possibly also my MacBook. Stay tuned for more on the latest Linux OS and what you can do with it for creative music making.

Indamixx Laptop @ Amazon: Indamixx Portable Studio Netbook Edition Model 2

(also available from Musicians’ Friend)

Five hundred bucks. In music tech terms, that usually gets you, what, a single app bundle? Now, it can get you a whole computer, pre-loaded with a bunch of music software. It may not be as powerful as a modern laptop, but it’s also in a cute, smaller form factor you can keep everywhere in case inspiration strikes, or balance on the corner of your Steinway grand. Meet the Indamixx laptop. Whether you want one or not, it’s emblematic of the ongoing commoditization of laptop technology, with ever-cheaper, lower-power brains.

Highlights:

• Brains: 1.6Ghz Intel Atom CPU netbook (looks similar to the Asus, but it’s actually Sylvania)
• energyXT bundled: Runs energyXT, the awesome music production workstation with modular features and some unique editing capabilities – sort of the “indie” electronic music workstation of choice
• Full laptop-like specs: a full complement of I/O including 3 USB ports; an 80 GB hard drive (not bad for a machine this size!)
• Custom Linux distro + apps: Tons of pre-configured Linux music production software running on a custom distribution called “Transmission” – with Hydrogen Drums, Ardour DAW, DJ software Mixxx (that’s three x’s to Indamixx’s’s two – don’t ask), and lots of other lovely tools
• Sounds pre-loaded: 2900 drum sounds, 350 samples + scratches
• Import sessions: The new Ardour Xchange imports from your existing DAW (worth its own article, I think!)
• Broadcast your sets: Included Internet console for streaming your live gigs, etc.
• Hosts Windows VSTs: An included Windows-compatible host for your existing plug-ins
• Bundle: includes 1GB SD card, free carrying case, free US shipping, a t-shirt, and 30 days software support while you get it set up

$499 for the whole bundle – stuff like Ardour Xchange alone lists for US$75, energyXT is commercial, and you get these other goodies, as well (the memory card, case, etc.). So I think this is very competitively priced.

More reflections from Liliputing, which is a must-read blog if you’re into netbooks. (And it’s the creation of Brad Linder, audiophile and NPR producer who occasionally checks in on mobile recording here.)

In a story I originally broke here, Trinity Audio Group has already built an all-in-one, ready-to-run Linux audio machine in a UMPC form factor, the Indamixx. I reviewed that Samsung Q1 Ultra machine for Keyboard Magazine, and was particularly impressed with the software configuration. I’ll be honest, though, personally I could never get that comfortable with the UMPC-style Indamixx, because I found input methods to be overly cramped, and the tradeoff for the UMPC’s extreme mobility is vastly trimmed-down performance – at a price (US$1199) that remains awfully steep. Touch is appealing, and it’s worth holding one just to marvel at the technological achievement, but in practice I just didn’t like the thing that much. I know some people feel differently – EnergyXT creator Jørgen Aase adores his – but you realize that maybe traditional laptops have something going for them.

I’m not alone. The netbook market has already more or less clobbered the UMPC in the market. Under the hood is the same enabling technology: increasingly power-smart, low-heat Intel mobile CPUs. They still fall well short of what the Core 2 Duo can do, but they’re getting better. And in the netbook, they have two massive advantages: one, they’re super cheap, even relative to bigger conventional laptops, and two, they’re in a familiar form factor that’s been made more compact.

Turns out, that whole laptop form factor isn’t so bad, after all. It tilts the screen up, and allows for a big screen. It provides ample keyboard input. It folds to protect the vital bits. It has plenty of I/O.

So, whereas the original UMPC Indamixx might have only niche appeal, you can bet the Indamixx netbook could be a huge hit.

You can pre-order the Indamixx laptop with a US$99 deposit, and guarantee delivery by Christmas by ordering by December 15. With USB2, you could easily plug in audio interfaces and keyboards, some of which have excellent support on Linux. On the downside, unlike something like the Lenovo S10, it won’t run Ableton (at least not with some effort – anyone tried WINE?) On the upside, Linux has audio features Windows XP doesn’t, it comes pre-configured with a bunch of software, and runs nicely on this kind of hardware.

I hope to test one of these machines soon. And yes, before people start protesting, there still is a great argument for conventional laptops — $500 will buy you a fairly impressive conventional machine, and you can install Linux on that, as well; with more of an investment, you could get a machine that easily smokes this one. I do like maxing out the capabilities of just those kinds of machines. But you have to admit, you can see some appeal to this machine, as well. And I do think some of the developments here, from the low-power CPU to the use of the Linux distribution, have some implications for all laptops. Stay tuned.

Indamixx Laptop Pre-Order Page

Trinity, the folks who have been pushing the notion of a Linux-based handheld audio studio for some time now, have launched a full product today. It’s called the Indamixx Mobile DAW, and it’s a full software studio running on Samsung’s Q1 Ultra (formerly known as an Ultra Mobile PC). In fact, it might more accurate to say that it’s multiple DAWs, as you have various, full-blown software choices you can use pre-optimized on a handheld computer.

For anyone unimpressed by people tapping on iPhones and such, this is the real thing. Software includes, among other things:

• Just-added special version of EnergyXT, the increasingly-popular music production tool (as pictured here)
• Ardour, the powerful, open-source DAW software
• Hydrogen drum machine, Seq24 sequencer, Ardour audio editor
• Powerful Linux tools: LADSPA and VST effects support, synth and sound tools, and utilities

You also get tools like Skype and Pidgin, plus the usual Linux Internet apps, so I could imagine this would be a really powerful tool to have with you in world travels. Find wifi, call whomever you like.

It’s all about form factor. Some people will, naturally, be perfectly happy with a no-compromises laptop. But for people who prefer a handheld machine that could fit easily atop a keyboard or music stand, this finally gives you some real power – and a full-blown Linux OS. (The addition of EnergyXT to me is really the killer app.)

The hardware features:

• 7”, 1024×600 screen and VGA output
• 802.11g wifi and Ethernet
• 40 GB hard drive (not sure about real-world track count on that; I’ll try to find out)
• 2 USB 2.0 ports, so you could use this with a MIDI or audio interface
• Touch screen and physical keys, plus an 8-way joystick
• 1G RAM expandable to 2GB, reasonably speedy (very much so for a mobile device) Intel processor

Cost: US$999 as a special intro offer through 8/31 or until supplies are gone.

Availability: Now.

Whether or not you’re running out to buy one of these, I think the message to developers is clear. You can no longer assume the traditional computer and mouse is the target platform. With touch capabilities in Windows 7 and likely on Mac OS, with killer apps on everything from the iPhone to the DS, the growth of Linux laptops like the Eee, and touch and mobile interfaces everywhere, the potential diversity of computing is finally being realized. That means UI design will increasingly have to accommodate alternative modes of control (like touch), scale to different screen sizes (including higher resolutions as well as lower ones), and think about mobile. And Linux – already capable of emulating Windows well enough to run many music apps, and ready to host VSTs – could have a new window of opportunity. The change may not happen immediately, but smart developers will be prepared for whatever direction their customers may take.

Indamixx Portable Studio Site

Open-source music and audio is finally delivering the goods: useful and unique tools that make sense even alongside commercial/proprietary software. And as a sign that the mainstream could get a taste of these tools soon, Intel is exhibiting at the massive Las Vegas CES consumer electronics show with Transmission, says Trinity Audio’s Ronald Stewart.

Transmission is Trinity Audio’s open source software bundle and live Linux distribution. It’s built for Trinity’s Linux-powered Trinity mobile studio device, which we’ll be seeing more of soon. At CES, it’s running at the Intel booth on the Samsung Q1 Ultra Ultra Mobile PC (UMPC). (The advantage of the Trinity over the UMPC for audio folks: XLR jacks, among other things.) But you can also run this free software on your PC — try the live CD link below. Haven’t tried it on Intel Mac yet, but that should work, too, theoretically.

Audacity [the open-source waveform editor]

Burn is a cd burn app

DJ is IDJ for live podcasting ( i love this with a mic)

Drum is Hydrogen [the simple but fun software drum machine]

Mixer is the Gnome ALSA mixer [for mixing virtual channels of audio on your system -- something not nearly as functional on Mac or Windows]

Mixxx 1.6 beta (rips with the touch screen grabbing the tracks and faders)

Record is Ardourino (Ardour is so awesome) [the open-source DAW]

Sequencer is Qtractor (another great app)

Synth is amsynth

Upload is an ftp app [so you can upload your tracks]

Zynaddsubfx is another great synth

For more description and links to the individual tools — an excellent selection of the creme de la creme on Linux — check the Transmission site. (warning: auto-plays audio!)

Transmission

But no need to have a UMPC or Trinity device to give this a spin. This live CD will do the trick. For Mac users, it even includes the native (non-Linux) Ardour for Mac, an excellent free and open source DAW for Mac users.

Trinity Live Master CD

Even as someone dedicated to proprietary software I really can’t live without (hello, Ableton!), I think there’s huge potential in using these applications for specific applications (like mobile devices), for collaboration, and file exchange. If we were really lucky, some of those major developers would start to build in support for, say, Ardour’s file format. But that’s the subject of another story.

Below: the Trinity mobile device getting celebrity treatment.

Ardour, the free and open source DAW for Mac and Linux, has already won some fans by providing robust audio multitrack features in free software, along with some unique innovations (like robust support for inter-app JACK audio routing). But one major complaint has been a lack of serious MIDI tools. MIDI functionality is baked in, but it’s not as full-featured as some might like.

That should change soon: Ardour is involved in Google’s Summer of Code, a seasonal code-fest that helps develop open source projects. Ardour creator Paul Davis describes progress on his Ardour blog:

Dave Robillard continues his work on Ardour’s MIDI recording, playback and editing capabilities as part of the Google Summer of Code program. Since the last screenshot (below), Dave has added color coding of velocity values, percussion tracks, two modes for delivering MIDI CC data (discrete+interpolated), and some basic editing operations such as quantize, note selection and pencil-based note creation & deletion.

Sounds great to me. Of course, it could rob Paul of the job of having to listen to whining forum/comment trolls complaining about the lack of Ardour MIDI. We’ll be watching — an update following the Summer of Code is definitely in order. I’d love to have a free DAW to use with students, for instance, as opposed to them (cough) pirating Cubase.

For mobile work, your choices have traditionally come down to one of two choices: either lug your laptop and audio interface, or get dedicated recording hardware with far fewer capabilities. We’ve been following the evolution of the Linux-powered Trinity mobile recorder for over a year now because we’re interested in what could happen between those two extremes.

Prototype Trinity recorders initially failed to impress on the software side: the bundled software focused on Audacity 2.0, a fairly basic waveform editor. That already allows far more than what’s possible with dedicated hardware recorders, but maybe not quite enough to warrant leaving your laptop at home. Since we last saw it, though, the Trinity has gotten two major improvements. First, it’s not naked any more; it’s got a lovely, brushed aluminum case. More importantly, though, it’s got an application worth writing home about: a new, mobile/embedded edition of the powerful, free DAW Ardour called Ardourino.

Ardourino isn’t just Ardour running on the Trinity: it’s a special, customized version of the DAW intended for mobile devices. You get the capabilities of Ardour, a full-featured open source DAW that also runs on desktop Mac OS X (natively, no less) and Linux, but adapted to smaller screens. That shows some promise for the open source audio software; I can’t think of any other major pro audio software that’s mobile device ready. And, of course, that also means you can work directly on your desktop DAW on the road, without any import/export of files.

Since the Trinity is running Linux, other applications are possible, too; one prototype photo already shows it running the Hydrogen drum machine.

For many readers, the Trinity rightfully has competition from laptops; you may just not want another device. Nonetheless, though, the Trinity provides an interesting glimpse at what the future of mobile/embedded audio devices might look like, and some of the potential of Linux for music and audio. As far as the Trinity itself, we look forward to learning more about the finished project.

Linux naysayers get mighty grumpy about all the Ubuntu hype. I can certainly imagine some Ubuntu fatigue, but Ubuntu is actually gaining some real traction in a way that previous attempts to be a “Linux for the rest of us” have not. For that reason, it’s significant that there’s an Ubuntu release for creatives — not just one niche group of people, like audio, but for multimedia creative work in general. We’ve seen Ubuntu Studio before, but the big news is that you can go and download it now, and give it a shot on your Intel Mac or PC:

Ubuntu Studio

Note that there’s no live CD version, so you will have to install it to try it (though if you’re curious about Ubuntu, you could use a live CD of that).

We’ll be testing Ubuntu Studio CDM over the summer, both for the music and motion side. I will say, though, the music and audio end of this release seems to pale in comparison to Ubuntu Studio’s video and graphics tools. There’s Ardour, yes, a terrific DAW, and built-in JACK support. Other than that, though, the choices are generally far weaker than what’s available in commercial and even free closed-source software — or, for that matter, even other Linux audio distros. Compare the 3D application Blender, or Cinepaint for video, which easily stand alongside commercial tools. On the other hand, there are lots of terrific music packages that just didn’t make it into Ubuntu Studio — and that’s okay, because it’s not necessarily that hard to install the other apps. And there is a full complement of JACK audio utilities and some neat toys (trackers and whatnot). The big remaining question will be how the distro itself does in terms of performance and ease of use, which we’ll definitely be testing here.

Before we get into another boring Mac vs. Windows vs. Linux argument, I have to say one sure-fire potential use for this is as an educational tool, as a common-denominator OS-with-apps everyone could use. So I’m eager to try it out regardless. It’s telling that Ardour just got renewed funding from SAE, the audio school — more on that soon.

If you are focused on music and audio, two other distros for me really stand out. One is the Debian-based 64 Studio. It’s been around a lot longer than Ubuntu Studio, it’s got audio performance as a major priority, and has a deeper set of tools and tweaks for audio users. There’s also Stanford University’s Planet CCRMA at Home, a tried-and-tested academic distro filled with unusual sound tools that you can’t get anywhere else. I saw the CCRMA folks at Maker Faire, and they were showing off their distro. The students really loved it, and I think one key difference is that there are real “killer apps” there that don’t live on Windows and Mac, all ready to run.

Ubuntu Studio still looks very polished, though, and if mixing in visual work appeals to you, it should definitely be on your list. Full audio package list. And “Swiss Army audio editor”? I wasn’t aware the Swiss issued audio editors to their soldiers, but I can’t say I’m surprised:
