Quick! What do you do in an emergency when you need to re-authorize software for a gig?

Good news: Ableton will not be “evil.” (see photo at right; thanks, Amanda.)

It happens: a hard drive dies, or you lose an entire computer and switch machines. Now, in an ideal world with no copy protection, this wouldn’t be such an issue, but most of us are fairly resigned to some kind of copy protection being a necessary evil. There’s software we rely on that requires some kind of authorization or unlock, if not a hardware dongle. That means you need to get a functioning copy of your software of choice up on your machine – fast.

Ableton Live, for one, has always had a relatively generous demo. It runs unlimited, with only saving and bouncing disabled. I have known Live users to, in a pinch, use that demo to save a live gig – just load your set into a backup machine and play. (For the same reason, I keep a fully bounced version of my sets, in case there’s some problem with third-party instruments.)

It’s like Mexican wrestling for people who enjoy, um, patching together interactive tools for music and visuals! And on one fateful Toronto day, the open source challenger took the prize.

As promised, a group of music tech geeks challenged DIY multimedia software environments Pure Data (Pd) and Max/MSP to a mano-a-mano contest of wits. These competing patching environments share interface concepts, code, and even a surprising amount of compatibility, but open source Pd and commercial, more polished-looking Max each have their own loyal converts. I’m pleased to offer the results – though I’m already hearing calls for a rematch in this heated rivalry. And there was DIY pong. And some kind of dancing … koalas?

Co-organizer Dafydd Hughes:

The event was a success - lots of fun, good-natured competition, beer and general nonsense.

Pd won 9-6, but several people pointed out that since there was only one person on the MAX team and two on Pd, maybe the score should have been 6-4.5 in MAX’s favour. Before the final Pong match the score was 4-2 for Pd. We then won Pong 5-4 and added the scores together.

We had a really good time and we’re already thinking of ways we could do it better next time and of variations on the theme.

Mari Kimura is an experimental string player extraordinaire, regularly venturing to the edge of what’s possible at the meeting of acoustic and electronic technology. GuitarBot is a “guitar”-playing robot (perhaps more reminiscent of a shamisen), an invention of Eric Singer, founder of the League of Electronic Musical Urban Robots. The two meet above in a lovely video – not new, but well worth watching any old time, as reminded to us by Richard Swelling’s Etherbomb blog. Mari writes in comments on YouTube:

HI, Mari here. For those wondering what’s happening: Behind the white box, there is a Mac and an audio interface. I am running a software MaxMSP, which is LISTENING to the pitch. loundess and the timing of the violin. The ‘patch’ I created in Max contains certain interactive instructions such as "listen to the E (highest open string on the violin)". For example in the beginning, if you listen carefully you notice when I play above E, it stops. Iinteractions change in predetermined time frames.

It’s a reminder that, technology aside, the key ingredient in electro-acoustic music is great musicianship.

Quite nice stuff! And the video is shot by my friend Liubo Borrisov; Liubo, if you’re out there, say hi.

Even with the success of beginner-targeted software like GarageBand, computer music production is still something a lot of musicians have only started to explore. And while there are computer-savvy players of every instrument, there’s no question guitars are underrepresented for the size of the market versus, say, keyboards.

Sonoma’s RiffWorks has been one software entry trying to change that, by combining guitar-centric features (amps and effects) with loops, multi-track recording, and collaboration features. As with GarageBand and Steinberg’s Sequel, loops, machines, and effects assist in quick song creation. But unlike those products, Sonoma also emphasizes collaboration, and is targeted directly at guitarists.

Now, they’ve introduced a free version of the software called RiffWorks T4. While it’s free, it does quite a lot – presumably to try to get hooked on online collaboration on song making.

• 4-layer song production
• Basic effects (Wah, Multi-band Compression & Distortion, Modulation, Delay, Reverb, Compression, and British Style EQ), plus IK Multimedia’s AmpliTube LE guitar amp/effects and Gallo Engineering’s Studio Devil BVC amp model
• An “InstantDrummer” drum machine/accompaniment tool with intensity, variation
• Online collaboration and online song sharing community

Online collaboration has always been a challenge because the physical size of the planet Earth actually means that true real-time collaboration is basically impossible with music. The solution is simply to provide music that’s synced, if not in real-time. Sonoma describes their solution: “As a track is recorded, it streams to other players and is perfectly in sync.” (In other words, it’s better to be a bar behind but in sync than a fraction of a second off.)  [Update] To clarify: unlike many online music collaboration services, you can work simultaneously on a song recording – see reader discussion in comments. This is a step behind eSession-style near-real-time collaboration, in that you hear full riffs at once. (eSession is synced to a metronome, though it can’t do “true” real-time, either, in the sense that you can on a local computer.) It is a number of steps ahead of most other online tools, however – and the real draw is the software editing and effects anyway, as combined with these community features.

That said, I think online collaboration could be fun, if Sonoma can get a healthy community going. Many musicians still prefer in-person collaboration for other (non-technical) reasons. But then, the two aren’t necessarily mutually exclusive, especially in our online-connected world. Sonoma tells CDM that over 1,000 people per day are signing up; now it just remains – as with other communities – to see how many get really involved.

Even if the online side doesn’t take off, perhaps the production tools will. Guitarists, if you do give this a try – or if you’re already a user of RiffWorks – we’d love to hear from you.

DIY 3D Interface: Tic Tac Toe from Kyle McDonald on Vimeo.

The Theremin, not too far off from its one hundredth birthday (start planning now), was a breakthrough in enabling a touch-free gestural control in space. Using the same principle that allows the Theremin to sense hand position, Kyle McDonald has created a 3D interface, and posted the process on Instructables. CDM gave him some of the inspiration:

Your recent post, "Theremin as AV Controller", inspired me to finish an idea that’s been living in my sketchbook. It operates on the same capacitive sensing idea as the Theremin, but in 3D — using just an Arduino, aluminum foil, and six resistors. I’m planning on using it as an instrument, interfacing with a wave terrain synthesis system. In the meantime, I put together a demo video and an instructable so other people interested in alternative controllers can experiment with it. The code is in Arduino outputs coordinates via serial, and the example code is done in Processing, so it’s only minutes from interfacing with your audio/visual tool of choice.

In the spirit of sharing, Kyle says he’d be happy for people to improve on the design: “If you think you can build one that is simpler and equally accurate, or slightly more complex and more accurate, share in the comments!”

DIY 3D Controller @ Instructables: “Make a 3D interface using an six resistors, aluminum foil, and an Arduino. Take that, Wii.”

Here’s the original post, which came from our friend Sarah Angliss, who’s been using the Theremin as a controller for A/V sets in Max/MSP/Jitter:

Updated: Kyle writes with some additional details on what he’s doing musically, and from where he draws some of his inspiration:

Resolume Avenue 3 Introduction from Bart van der Ploeg on Vimeo.

If you’re interested in audiovisual performance as well as audio, here’s an app to keep an eye on. Resolume “Avenue” 3, announced today, is a ground-up rebuild of a popular VJ app. Now, things like GPU-native video may not mean much to the musical readers of this site. But how about features like this?

• Beat-synced audio triggering alongside video – using the soundtrack inside video clips, or using separate audio files
• VST audio effects, synchronized to visual effects and controls
• MIDI and OpenSoundControl (OSC) support
• Cross-fading of audio and video
• Beat-synced loops

We’ve been playing with an early betas at the live visualist-oriented Create Digital Motion and will have detailed hands-on reports soon. In the meantime, here’s a detailed look at what’s in Resolume Avenue 3:

Resolume “Avenue” 3 Announced: The Audiovisual App to Beat? [Create Digital Motion]

You can see the results above with Missy Elliot, but naturally this could also be used with very different source material as a glitchy audiovisual experimental ambient set, or as a way of triggering videos and audio backing tracks alongside a band.

It’s not without limitations. You can’t yet use VST instruments, so you couldn’t drop a synth or sampler into your visual set and play that – at least not in the first release, due in September.

But it’s clear an audiovisual convergence is happening. You can add this to the recent debut of GrandVJ, a live visual app with a virtual MIDI keyboard in the display and “Synth Mode” for triggering, or, at the opposite end of the spectrum, the addition of VST effects support in the visual patching environment vvvv. And we’ve likewise seen interesting ways of combining Ableton Live and other music apps with live visuals, as in Momo’s tutorial for A/V cutups with Lucifer.

Gustavo Bravetti has put together a free, exclusive FM8 drum kit in Ableton Live for CDM readers. More on the kit, FM8, and how to make the most of it, plus our download, at the Kore@CDM NI minisite:

Free Exclusive Download: FM8 Drum Kit for Ableton Live from Gustavo Bravetti

Here’s what the kit sounds like, using the demo clips included with the package (naturally, you’ll want to make your own patterns):

fm8kit.mp3

I love that it’s a synth kit rather than a sampled kit, as you can do things like this — just a quick demo I whipped up, same clips, modified only using synth and effects parameters in FM8, to "mess up" Gustavo’s pristine kit:

fm8kit_2.mp3

A quick survey revealed quite a few Live users I know who use both Operator and FM7 or FM8 from Native Instruments, proof positive that you can never have too much synthesis or too much FM. I know I regularly swap between the two, plus Image-Line’s Sytrus.

The kit is calling out for a Koresound and a full Live Drum Rack, so I’ll see what I can do. But I really do enjoy fabricating drum kits with synths. Whether I do it terribly well or not, I always feel closer to the resulting sounds. (Previously, Gustavo made bass drums and snares with Operator in video tutorials, though I prefer the FM8 sounds he’s done, personally!)

Brian Kane sends along this whimsical proposal for iPhone/iPod Touch users reading tab. "It’s a portable practice device, also suitable for performance," says Kane of his concept. It’s like a harmonica holster, but for your tab. Attach this to yourself, pull up tab of a song, and fake your way through any tune you like. (Brian also suggested "Practice anywhere; get laid quicker." I’ll leave that to you to determine.)

No, you can’t buy this yet. But never say never. It’s certainly not the strangest idea for an Apple accessory I’ve ever seen.

Study for musical assistive device [at Brian's blog.slashboing.com]

Amidst the news of GigaStudio’s demise, we’ve heard some isolated calls to open source Giga itself. There’s even an Open GigaStudio petition (via musicradar.com). The likelihood of open sourcing a code base as large as Giga’s, though, seems extremely slim. Making an open source project from a commercial developer successful requires a number of critical ingredients. You need the will of the company that owns the code, of course, but also:

• a code base that is accessible to people who have never seen it before
• code that’s free from "encumbrances" or code or concepts proprietary to a third party, such as licensed libraries or materials covered by patents (and thus usually requiring removal)
• an active community of developers
• a process for maintaining development

Or, put more simply: you have to fully own the thing, you have to want to share the thing, and there has to be a group of people who can work on it productively. Even satisfying one of these is unlikely here, let alone all of them.

In case you missed it in comments, amidst the news of a major pro sampling product being discontinued, reader Darren Landrum is interested in offering a free/GPL open source framework for samplers:

The LinuxSampler project offers GigaSampler 3 compatibility for Linux and Windows, so it’s already an open alternative for dealing with your orphaned Giga sampler files. (Naturally, you could also look to a number of Giga-compatibility samplers on the market.)

But the open source community has long been under fire — often rightly so — for simply copying proprietary software rather than doing something new and innovative. I enjoy "new and powerful," so that sounds like a great idea, and that’s what Darren is proposing. He writes:

What I want to do is build a code framework (not to be confused with a library) that will contain classes for handling streaming sample playback, resampling, and all that fun stuff, as well as directed graph building for DSP. From here, the framework can be used to build monolithic applications for sampling and synthesis, as well as a Reaktor-like application, if we do it right.

Yes, it would be better to split things out into libraries, but that takes a lot more work, and I’m tired of things not happening. The sooner we can get some code working, the better.

I should also mention that there are existing open source libraries we can and will leverage, like libsndfile, libsamplerate, libfftw3, and the Rubber Band library, so we won’t be starting completely from scratch.
