Turning music and sound into three-dimensional worlds often yields something that fields like a trip through space. But this feels like a real trip. Through pulsing, glowing starfields, “Versum”‘s audiovisual movements are brain-bendingly transformative. Artist Tarik Barri has created an integrated world of sound and image that makes the interface and the compositional realms seamless. It seems as though this really is a musical universe, through whose harmonies of the spheres you can fly like. Boldly going, indeed.

Ingredients: Max/MSP/Jitter, Processing, Java, SuperCollider, GLSL [the 3D shading language], and … some serious skill and time, I imagine.

The work has been in development for some years (not surprisingly, given the results). But it surfaced again as we brought up the 3Dconnexion SpaceNavigator hardware as a practical controller for 3D. See Create Digital Motion:
Look at Me, I’m Flying: SpaceNavigator Hardware + Blender

Tarik’s work resurfaced after a presentation in the UK. Reader janklug writes:

I’m just back from the M4_u Max/MSP/Jitter conference in Leicester (was great, btw), where Tarik Barri presented his project ‘Versum’, both as an installation and as a performance.
The user (and in case of the performance, Tarik) navigates through this incredible 3D-space-sequencer-universum with the help of a SpaceNavigator; glowing objects floating in this space produce sound, and as you approach them, they even give this nice doppler effect…
It was totally amazing to be able to float between pulsing rhythm-planet-objects and shiny drone-beams; navigation was easy and natural. Tarik uses a combination of Processing and Max/MSP; don’t know which one the SpaceNavigator is connected to.
Having tried this, I immediately ordered one; I think it also could be a great interface for M4L…

Significantly, it’s really the act of flying that controls the music. That remains interactive, but it’s the movement through the three-dimensional space that determines what you hear. As the artist explains:

This virtual world is seen and heard from the viewpoint of a moving virtual camera with virtual microphones attached. This camera, controlled in realtime by means of a joystick (or any other kind of controller) moves through space, similar to how first person shooter games work. Within this space, I place objects that can be both seen and heard, and like in reality, the closer the camera is to them, the louder you hear them. So when the camera moves past several visual objects, you simultaneously hear several sounds fading in and out. Consequently, the way the camera travels past them actually causes melodies and compositional structures to be seen and heard.

The visual position of each object coincides with the panning of its sound: objects to the right of the camera will also be heard on the right, and those behind the camera will be heard from behind in case a surround speaker setup is used. This principle also applies to the Z-axis, meaning that sounds can be heard coming from above and below if the speaker setup supports it.

That’s the essential question, to me, when looking at 3D environments for music. What about the dimensionality will interact with the music? Is it something spatial, or will there be other sorts of interactions? (New Zealander-turned-Berliner Julian Oliver worked extensively with game engines, for instance. One solution for him was modifying the “gun” in those games to be an implement for doing things in the space, turning swords into plowshares after a fact by making the gun produce music rather than kill virtual entities.)

So, now you’ve seen some of the technical demonstration. But Tarik uses his work as an environment in which to make audiovisual performances. Here’s what some actual live playing looks like, in a beautiful, meditative piece called “Eleven”:

In fact, the biggest challenge to me of a piece this awesome is that you want an immersive environment, not just the small, rectangular screens that are often all festivals and venues can afford.

Holodeck, anyone?

Writing code for music may still seem a remote notion to the vast majority of even geekier digital musicians, but as exemplified by the language Overtone, it looks very different than coding once did. Whereas sound code was once a type-and-render affair, new coding environments focus on live coding. They use elegant, lightweight modern languages that take up less space. And they can be surprisingly musical, coming remarkably close to just typing “play a c major chord.”

Not to say that you won’t look plenty geeky doing it — but, hey, if you can’t impress slash frighten your friends a little…

Using a brew of powerful free and open source tools, all available via GitHub and running here on the Mac (though any OS will work), contributor Sam Aaron walks through the program at top and demonstrates some musical examples. After the jump, a much longer screencast walks you through how to get up and running with the emacs text editor for live coding.

Key ingredients:
overtone @ github
emacs live coding @ github
supercollider for sound production
clojure, the language, modern dialect of lisp

Features, as described by the creators:

Overtone is a toolkit for creating synthesizers and making music. It provides:

• a Clojure API to the SuperCollider synthesis engine
• a growing library of musical functions (scales, chords, rhythms, arpeggiators, etc.)
• metronome and timing system to support live-coding and sequencing
• plug and play midi device I/O
• simple Open Sound Control (OSC) message handling

Note the MIDI support — code, like many other things on the computer, isn’t very tangible. But you can quickly go to MIDI or OSC for some hands-on control of what you’re making. I have to say, some of this is quite a lot easier and less abstract than what you see in a Max/Pd-style environment. We’re blessed to have such choices in music making. Let us know if you try it out.

CDM’s Matt Ganucheau contributed to this story in San Francisco.

Presenting artists from around Earth to viewers around Earth, a center in Beijing has found a way to do live performance for a sleepless world without waking the neighbors.

Let me start out by saying this: if you read CDM from China, say hello. We’re in the wrong language, we have no translation, and I seriously doubt our Texas data center is delivering this site with any speed (until we upgrade to an international CDN), but the only reason I still run CDM is in order to reach people, and to hear from a wider world that knows things I don’t, and imagines things I can’t. And if you’re not in China, we still get very nice, high-quality video streaming. Think about that for a second: we’re on a planet that has a circumference between poles of about 24,860 miles (40,000 km), and we can share video and recording as if we’re in the same room. That’s pretty ridiculous; almost more impressive than recording itself. (I had similar thoughts a few years ago, somewhere in the jetlag going from New York to its nearly-furthest point on the globe, Perth, Australia.)

Shan Studios is a platform for artist conversations, residency, audiovisual performance, and learning. If you’re in Beijing, China, this center is forging connections between European audiovisual practice and China — and it’s a place where you can go to learn tools like Ableton Live, SuperCollider, and Max/MSP/Jitter. But if you’re anywhere else in the world, tonight/today you can watch a performance of audiovisuals. (That’s 11:59p Beijing time, 4:59p London time, 11:59a New York time).

The best part of this: by broadcasting to the Web but being silent in person, the performance won’t disturb the neighbors.

Using an array of webcams, DIY synthesizers, medical equipment, projectors, busted radios, and many unconventional instruments, the performers will create a completely immersive audiovisual experience in the Shanstudios sound laboratory. But the actual performance space will be silent – as to not wake the neighbors and simultaneously experiment with the best distortion box ever created (the Internet!) – all sounds will be processed digitally and virtually. The event is entirely exploratory and will hopefully lead to greater investigation of the Internet as a viable medium for other such experimental performances.

Shan Studios is the brainchild of multimedia artist Sheng Jie (gogoj), who returned from studying in France with artists and education to share with young people in China.

That pattern is very familiar. In fact, it’s hard to imagine where we’d be now without international exchange. First, research centers exchanged knowledge and technology – think, for instance, American Miller Puckette visiting Paris’ IRCAM to go on to create what would become Max/MSP, but also investigations spanning Brazil, Japan, Australia, and so on. With more democratized access to technology (read: s*** gets cheaper), that’s gone beyond any centralized locations to knowledge and artistic ideas that cross all six populated continents.

Whereas this was once one-directional – even in the US, aspiring artists often headed to Europe – now I think the compass could spin in all directions.

Anyway, I should be quiet so you can go watch the video:

http://www.livestream.com/gigonline (something interesting happening there already, and I think they’re just warming up)

Side note: if anyone is interested in making a Mandarin-native site companion to CDM, do get in touch. We’re not, ahem, sponsored by Intel, but I can see what we can do. Hell, I’d be pleased to have one page, or content in English that does a better job of what’s going on on the other side(s) of the globe.

Electric guitar pioneer Les Paul is one of the all-time greats in music instrument invention, so the guy clearly deserves an animated Google Doodle of his creation that you can play. Strum chords, pluck with the mouse, and even record phrases on Google’s homepage. (See video, above.) Since Google Doodles are archived – and since you can look at the code by choosing a View Source feature in your browser – these little novelties also have a life beyond their one day of glory. (Note, you may need to visit the US site if you’re in a part of the world that doesn’t have this Doodle, since they’re localized.)

Here’s where things get a little geekier:

Using the free and open source tool SuperCollider (Mac, Windows, Linux), composer and coder Nick Inhofe scripts Google’s interface, using the ability of SuperCollider to talk to keystrokes. You can download SuperCollider for free and try it out – it’s an insanely powerful real-time synth and processing engine – or just hit the Google shortcuts to hear the results. Full details:

Good, clean fun.

How much can you do with a single line of musical code?

Scoring music using archaic-looking (but relatively fundamental) audio techniques, a group of composers has produced a free album. Each track, produced in the open source, multi-platform audio tool SuperCollider, is produced via only 140 characters of code. The work ranges from electronic grooves to droning ambiences to hypnotic melodic patterns… and yes, a few strange sounds. You can listen to the output as a conventional album, or if you install a copy of SuperCollider, you can run the code yourself – some of the tracks will sound different each time the code is executed.

The album, sc140, was released earlier in the fall but I didn’t get a chance to write about it; readers reminded me as the release of Mixtikl 2 yesterday brought a similar generative score-tweeting feature. Mixtikl’s approach is a little different; SuperCollider here is building sounds from scratch, whereas Mixtikl is tweeting higher-level information about a mix.

All of the code from the project is accessible, so this is an interesting way to learn about the capabilities of SuperCollider, and to find some of the commands you might want to understand if you’re delving in yourself.

If you’re not quite ready for writing code, the track audio is Creative Commons-licensed (BY-NC-SA 3), so you can sample the audio, as well.

Recreating the THX Deep Note

7up 2.0 – Introduction from makingthenoise on Vimeo.

What if the world of musical performance suddenly started moving a whole lot faster? That’s certainly the case among a handful of monome- and grid-wielding electronic artists.

In an evolutionary breakthrough, what previously had appeared in a period of months is showing up in a period of days, as long-simmering ideas come to the fore. Spurred by the blank-slate, minimal grid of the monome (and its design as mirrored in similar controllers from Livid, Novation, and Akai), musicians are re-imagining the step sequencer in new permutations. Many of these creations in recent days have been coming to Max for Live (site | cdmu tag), taking advantage of the potent combination of Live as a host, third-party plug-in instruments as sound sources, and Max’s own capabilities with sequencing and sound. But it would be a mistake to see this as a phenomenon limited to Max for Live. Other development efforts, built in free tools, work from the ground up instead of the top down, and may use code in place of patches. These efforts are running in parallel, taking ideas from one another, responding to each other as a challenge. And that could make the coming months very interesting, indeed.

What’s exciting to me is that a set of ideas is emerging that may go beyond any one tool. Even past the grid, what we see is people beginning to refine the idea of live electronic performance into reusable, modular components. There is a greater sense than ever that what computer performance is treads a line between composition and live playing. At the heart of that concept is embodying both in an “application,” and making that application work on the grid.

7up 2.0 Arrives, in Max for Live

The biggest news is that 7up, the popular multi-page, multi-module performance app for the monome, is reaching a big new release. 7up 2.0 builds upon an earlier version written as a standalone application in Java.

7up takes the grid and builds a single performance tool that has multiple functions. One strength of this approach is that, even with 7up’s various capabilities, controller assignments are fixed. You can learn 7up and build muscle memory with it. Equally significant, you get a set of predictable modules for various tasks, as pictured. stretta’s work, also using Max for Live, goes another direction, making the monome a generic controller for any number of performance “applications.”

For people working with Live, 7up is more functional in Max for Live than it was as a Java standalone. Among other things, creator Adam Ribaudo (makingthenoise) notes:

• 7up components install into your normal device library
• Drag and drop components to start using them
• Extensible components mean community members can build their own in Max
• Virtual MIDI no longer required

stretta, Live, and the Musical “Application”

maxforlive: monome integration from stretta on Vimeo.

Matthew Davidson, aka stretta, has long been both a virtuoso performer and master developer for the monome. Now, he’s going one step further, to try to make the undifferentiated grid of the monome work as a fully-functioning control surface, integrating multiple applications without ever having to leave the monome’s buttons.

It is one thing to adapt max patches for maxforlive but it is another thing entirely to construct them so they can handle multiple instances without stepping all over each other by accessing the same data. Then there is the issue of telling monomeserial which instance has control of the monome hardware.

I wanted to make it elegant to use. For example, if you click on a track in live that has a monome application running, that monome application is in focus on the hardware. It is this level of integration that makes maxforlive so appealing. So, now you can run as many obos, polygomes, stepfilters, or automatorgators as you like, and the monome switches between them effortlessly.

“Applications” and “musical compositions” take on interchangeable meanings. When stretta uses his “polygome” creation, it is an instrument, a composition of sorts, and – in the context of Live – a device. We’ve long lived with the ability to introduce new sounds and instruments into a studio simply by connecting them. With Max patches operating as modular compositions, you can drag and drop interactive musical ideas. (Okay, granted, such things appeal to the small portion of the population who can express their ideas in Max patches, but if you do count yourself among those numbers – or if you’re just lucky enough to be stretta – it’s all pretty amazing.)

Watch what happens as stretta drops polygome into a Live set:

maxforlive: polygome from stretta on Vimeo.

This certainly illustrates the advantage of Max for Live, for those who want a host for Max patches. As stretta puts it:

maxforlive simplifies monome workflow. For example, if you want to use polygomé with a DAW, you must open your DAW software, open polygomé, set up sync in polygomé, set up sync in your host app, set up MIDI output routings from polygomé, set up MIDI routings in your DAW. There is a lot of overhead. With maxforlive, you simply drag polygomé into your track as a MIDI effect. Then you can start playing immediately. There is no setup. Everything is in sync.

stretta hasn’t yet released this new version; that will come soon, so stay tuned.

…and Parallel, Free Software Solutions

Here’s an illustration of how the Max inside Live world might intersect with people working in very different ways. Inspired by the same problems stretta is trying to solve, there’s an effort to build tools well beyond Max or Live.

Brian Crabtree (tehn) has raised discussion of potential for a new monomeserial that would use OSC in a standard way to talk to multiple “applications,” across ports. That could be a number of Max patches running in Live, or a Max patch and a Processing sketch, or anything else. And it could ultimately have implications for hardware other than just the monome.

Ohm + Max for Live

LividStep: step sequencer made in Max For Live from Livid Instruments on Vimeo.

For another view of how you might make a grid work with Ableton Live, here’s a glimpse of Livid’s Ohm64/block hardware in action with Max for Live. In this case, the grid itself replaces the mouse for what you might have done previously onscreen, arranging a sequence. Livid Instruments writes:

This details the major functions of Livid’s Max For Live device, LividStep, including playback, how to: add and change sequences, control timing, navigate Live, and control instruments, all from the Livid controller.
The device works in Ableton Live with Livid ohm64 and block MIDI controllers. The device creates an eight step sequencer on one row of the 64 button grid. Fill eight live tracks with eight devices to fill the grid. Each sequence has independent time control for a huge variety of rhythmic possibility.

And, if you make it to the end, yes, the irritation at those who don’t use a Livid controller is real and palpable

Livid’s patches are open, so this approach doesn’t have to be limited to Livid hardware.

Little Scale’s Standalone Sonic Creations

Little Scale’s efforts for the Novation Launchpad are aggressively simple, and beautifully so. Sebastian Tomczak is known primarily in the chip music scene, so the minimalist aesthetic is definitely part of his work. (Not to be confused – as I did initially – with Ripple, a framework of musical tools built by Morgan Packard in SuperCollider.) It illustrates that there doesn’t really have to be a UI; the Launchpad sequencer can run purely on the monome. (Add embedded hardware into a monome case, and you could have your own DIY musical instrument, standalone, without a computer as such. But that could come later.)

Sebastian is doing interesting like this “waveform editor”. It could certainly also be a prime candidate for a SuperCollider version.

Both of these projects were built with Max 5 standalone, though they could work nicely in Max for Live or other environments.

Gridism?

There’s just a handful of people involved, scattered geographically around the globe, but something is definitely happening – even as these artists work in relative isolation.

I think you can thank, in part, the limitations of the monome grid. Deciding to restrict the interface, and building something from scratch – whatever the development tool you use – is causing people to really focus on the musical idea they wish to express.

Of course, that means you don’t need a monome or Max for Live or anything else. The real power here is focusing on what you’re controlling live, and using restrictions in one place to breed creativity elsewhere. (Translation: what can you do with an 8×8 grid with no velocity sensitivity? Be creative.)

Want to make a splash among the aficionados of digital sound? Releasing a software instrument emulating a broad collection of vintage digital synthesis chips from game and computer systems seems to do the trick. See my look at that software, and just as importantly, the chips that inspired it.

Within days of the release of Plogue’s Chipsounds, we have a couple of fair reviews of the new tool. Already got Chipsounds? Plogue’s David Viens has released screencasts showing you how to use it. Curious about other ways to explore vintage 8-bit sound? We’ve got that, too, in samples, hardware, and even SuperCollider code.

Reviews are in

Torley has an extensive video review – amazing stuff for something just days old – shown above. Gisle Martens Meyers has a review, too, on the blog Ugress. One complaint is that the plug-in is multi-timbral, rather than requiring different instances. In turn, automation is in the form of MIDI Control Changes, not parameters, since parameter automation really doesn’t deal with multi-timbral plug-ins. But all in all, you can get a lot from both reviews, plus a look at how the software works. There’s also a sense of where the software could go in future updates.

The discussion of Chipsounds has also brought other efforts to resurrect vintage, 8-bit sounds.

Get Your Chip Fix

This is by no means comprehensive, but here are a few of the best goodies readers have pointed out in the last few days:

Free Samples: Little Scale, aka Sebastian Tomczak, has been busy. He’s added sample packs of his own, including a Friday release of the Commodore 64 SID. Add that to Sega Master System, Mega Drive, speech chip, and Atari POKEY and TIA. These are just samples, so rather than being a turn-key solution as Chipsounds is, they’re more of a construction set – though that could make them useful in other scenarios.

C64 SID Sample Pack [little-scale]

Go Hardware! And, in turn, if hardware fires you up more than software or samples, Sebastian has done some lovely work connecting the actual chips to MIDI interfaces.

And here’s the documentation on how to do it with the free and open hardware Arduino platform

Other hardware solutions:
A DIY TI SN76477N-based Voice Module, comprehensively documented (a heck of a lot fancier than the Arduino stuff I wanted to play around with)

SuperCollider Code: For SuperCollider fans, Fredrik Olofsson (aka RedFrik) has built emulations of vintage chips in the object-oriented sound coding language. That’s a doubly delicious thing: aside from allowing you to make 8-bit sounds in the free tool, looking at his emulations is a great way to discover more of what you can do with SuperCollider. You can continue in code the kind of elegant, minimal synthesis design work the early creators of the original chips did in hardware. (Thanks, Howard S and Morgan Packard for the tip!)

SC Code [and a lot of other great SC code there, too... bookmarked, downloaded.]

Video walkthroughs

I know quite a few readers did pick up Chipsounds, so you’ll be pleased to know – in case you missed this – that there are some video demos that walk you through how the tool works. This also gives a better idea of how the software itself functions, since I got distracted waxing rhapsodic about the chips!

As my piano teacher used to say to me, “that should keep you off the streets.”

Enjoy.

Showcasing amazing projects is a good thing. But we know that no creation emerges fully-formed. They start from nothing, with lots of mistakes along the way. You get help and ideas from other people. And you need time.

So this month’s Handmade Music in Brooklyn we’re declaring an Open Lab. Got a kit lying on your shelf, waiting to get made? Got a half-finished project that needs fixing? Just want to hang around some musical and visual DIYers and see what they’re up to? And just need a few hours to make some progress? That’s the idea.

Software projects, hardware projects, gear hacking, circuit bending, coding, patching in Reaktor or Pd or Max – it’s all welcome.

We also have a very special guest this month in the form of Morgan Packard, a talented multi-instrumentalist and computer musician (video at top, with live visuals by superDraw creator Joshue Ott). At 7:30p, Morgan will show off his free Ripple musical environment, built on the powerful open source SuperCollider code-for-sound platform. It’s a great chance to see what SuperCollider can do, how a scratch-built environment can open up musical possibilities, and what you can do with Ripple yourself.

Full details: Handmade Music Brooklyn: Open Lab, Featuring Morgan Packard’s Musical Code [handmademusic@noisepages]

Facebook Event Page

The whole event runs 6:00p-11:00p at 3rd Ward Brooklyn. As always, it’s completely free. Be sure to bring your projects and the tools you’ll need; we can provide power, a PA, space, and other folks to hang out with. And we can help give you an excuse to set aside a few hours of time.

We’ll also be taking notes on how the setup works, as we know this may be something other Handmade Music events want to try in your neck of the woods.

The beauty of using touch for controllers is flexibility. Sure, you give up tactile feedback – but you can also quickly make your own layouts, make touch controllers an ideal complement to your existing hardware gear (the stuff with physical knobs and faders and pads).

For that reason, we’re all eagerly anticipating an upcoming version of the awesome OSC-based iPhone/iPod touch controller, TouchOSC.

http://hexler.net/software/touchosc

The included layouts are already fantastic, with rotaries and virtual buttons and multi-faders and toggles and X/Y pads. But custom control would be even better. Creator hexler writes CDM with the latest:

The long-awaited update to TouchOSC that will allow for custom layouts has just been submitted for review to Apple,
so I hope that as soon as next week it will be available as a free update to all users on the App Store.

Together with this release (1.3) there will be a free editor application to visually design and upload layouts to the device. You can take a look at the last beta version I published if you want, there’s both Windows and OS X versions available, but I will also prepare a Linux version as soon as possible, of course without the new version of TouchOSC this is but a preview of things to come:

http://dev.hexler.net/touchosc/touchosc-editor-0.7-osx.zip
http://dev.hexler.net/touchosc/touchosc-editor-0.7-win32.zip
http://dev.hexler.net/touchosc/touchosc-default-layouts.zip

And nicely enough, the editor is built in cross-platform Java, which I think makes a whole lot of sense. (Go Java, Python, etc., rather than getting stuck in hard-to-port platform-specific stuff like Cocoa.)

Thanks, hexler! I don’t have a video of the new features yet, so instead here’s a nice novelty – the beginnings of a creation using the free SuperCollider (which runs OSC natively) in combination with TouchOSC to make a custom step sequencer. Should fuel other ideas, too:

SuperCollider, super fast: UK-based experimental musician mcldx has produced a 60-second intro to SuperCollider. Naturally, you won’t learn SuperCollider in one minute, but what’s nice about this is it does explain the very first steps you would take to get SuperCollider running – and because SC doesn’t have a single-window, “do everything here” interface, that first step actually confuses a lot of people.

Have a look, and you’ll at the very least understand step one. From there, you can start diving into tutorials and making other sounds. SuperCollider will repay an investment of time: it’s an elegant language, runs a really efficient synthesis engine, works with OpenSoundControl natively (and now even builds its UI in Java’s Swing for cross-platform compatibility), and has some incredibly powerful tools for things like manipulating live sequences.

You’ll find additional help built into the tool. Some quick platform-specific notes:

• Linux: On Ubuntu, check out the nice integration with gedit, the default GNOME editor. It makes SuperCollider feel a little like Processing.
• Mac: Apparently Safari 4 beta is causing trouble with the online help editor if opened from the menu.
• Windows: I couldn’t get any love from the 3.2 build on Vista (sound driver problems), so I tried 3.3 “alpha” – and found the alpha perfectly stable, and an easier install.

Via fritcrate’s hackday blog.

Now, I think we should apply this to other things, but even faster – like ten-seconds:

• Ableton Live: Okay, see those rectangles? Put things on them! Trigger them!
• Sibelius: Just keep clicking “next” on the wizard, then eighth note, then type note names look for the blue arrow click and keep typing!
• Max/MSP and Pd: Quick, add a – box and connect to other boxes. Toggle bang metro 30 now you have a metronome!
• ChucK: Ummmm…. “SinOsc s => dac;”?
• Processing: setup, draw, size 800 by 600, and erm, line(0,0,mouseX,mouseY) and screw around for a while.
• A Yamaha DX7: Okay… plug this in and… jeez, I don’t remember button sequences. Try to find presets? Play something?
• A Moog Modular: Jacks. Knobs. Cables. Now go. It’ll sound awful and you’ll run out of cables. But you’ll have a great time.

Other suggestions welcome.
