Ever feel like you’ve found the seam dividing past and future?
The past: restrictive UI frameworks requiring pages and pages of code to produce dated-look 2D displays. Proprietary software with rigid interfaces. Input bottlenecked through the x and y coordinates of a single mouse pointer.
The future: UIs whipped together graphically or with a few lines of code. 3D mixed with 2D. Open-source, friendly frameworks. Creating your own interface or drawing upon a community of creative software makers. Input that uses multitouch for gestures, collaborative input, manipulation of 2D and 3D space, and … well, just a lot more fun.
There’s no need to wait around for the future. Creative software inventors are building it for themselves. Here are two of the most promising multitouch interface projects I’ve seen in my inbox.
In no time at all, you’ll be painting a cow! (Okay, more on that in a moment…)
Want to interact with your computer musically using physical objects and other fancy-schmancy, science-fiction-y interfaces? Don’t want to rely on Microsoft or wait until 2019? You’re in luck. It’s like Christmas for DIYers and interactive futurists.
Enter LusidOSC, a set of protocols, libraries, and useful code, and Trackmate, a clever and cheap-to-build system for tangible interfaces. Together, you’ve just got a bunch of tools to help you start playing with blocks — erm, experiencing new spatial interfaces.
LusidOSC, the library maps “spatial input devices” – really, any tangible devices or sensors in the real world – to applications, like live music or live visuals. It uses the network-savvy OpenSoundControl protocol. The library is available now for Processing, with Java, Python, Flash, and C++ in the works.
LusidOSC, the apps/code: a set of Processing utilities to get you started includes a basic example app, command launcher, playlist mixer, and a MIDI sequencer. You can build on these for your own Processing apps.
Your own input device: Tags? Sensors? Markers? Regions? Fingertips? If it’s in physical space, you can map it via LusidOSC. Or, if you want a place to start, try:
Trackmate: A project of MIT’s Tangible Media Group, Trackmate lets you affix tags to any objects you want and use them as an interface.
LusidOSC is just the protocol; it’s physical applications like Trackmate that get really interesting. In these economically-challenged times, Trackmate gives you tangible interfaces for next to nothing. All you need is a computer (Mac, Windows, or Linux), and a camera (even a webcam will do). Print out randomly-generated tags in the free and open source software, stick them on stuff you want to use, and go to town.
You can make your own Trackmate surfaces out of hardwood or plexiglass for as little as $40 in parts. There’s even a Processing-based simulator app so you can experiment without the physical objects. (Good for troubleshooting on the bus or plane, I imagine.)
Trackmate is just one project, though; LusidOSC promises to support other interface ideas, too.
Alternatives:TUIO, the protocol used in the Bjork-endorsed Reactable project marches forward, as well. And as both projects are open source, there could be some cross-pollination. I hear a revised TUIO is coming, and in the meantime, LusidOSC acts as a gateway to TUIO.
The step sequencer. The sixteen-pad drum machine. The piano roll. The step sequencing piano roll. The waveform editor. The multi-track recording. Live music is a dynamic and changing phenomenon, but much of our technology assumes fairly predictable interfaces with time. Elysium, which we saw early this week, breaks out of that mold by defining generative systems that live on a hexagonal grid or “honeycomb.” There’s lots of great reader feedback on that story, and Elysium’s creator wrote in to talk a bit about what influenced him.
I want to highlight two sequencers that you play as if they’re games. (Just don’t play a Vulcan – they always win.)
Robots on a Grid
Al-Jazari is named for a 13th-Century scholar and musician who apparently invented an entire band of water-powered hydraulic robotic musicians with more than fifty facial and body movements per song. (Okay, that clearly deserves a separate post later. So, our Western education is so eager to avoid the achievements of Arabs that we skipped over the fact that he basically invented Disneyland in the Middle Ages.)
Al-Jazari in the 21st Century iteration takes the idea of robotic agents and builds a sequencer around them. Creator Dave built a grid on which you can give the robots symbolic instructions (like up, right, down, left), selected from a gamepad. Each grid square represents a note, with pitch modulated by moving bricks up and down. Like Elysium, the music is generated as events are triggered on the grid. And like Microsoft Research’s (non-musical) game Kodu, the gamepad and a set of symbols make what is essentially scripting easy and transparent. (Few would likely call this “programming” because it doesn’t look scary, but that’s what it actually is.)
Al-Jazari is open source, built in the elegant coding language Scheme (a Lisp dialect) atop a game engine called Fluxus. Dave has extensive documentation on its development, and not only the code but even the textures and models. You can use this yourself on Mac and Linux, but it’ll require some messy compiling. (Thanks for this link, MattH – this is layered with things that blow my mind!)
Mark Burton’s reacTogon was the influence for Elysium. It’s a “chain reactive performance arpeggiator” – that is, it takes the usual, static, repeating patterns of an arpeggiator and turns them into something altogether different, by allowing events to transform dynamically in two dimensions across a hexagonal grid. The interface is a multi-touch controller with physical objects, so there’s a tangible element, as well.
Looking at reacTogon alongside Al-Jazari really demonstrates some of the advantages of a hexagonal grid versus the more traditional square grid. (And if you think about most musical applications, most of what we have is relatively non-dynamic right-angle grids. There’s movement, but only left to right, with start/stop or loop points. One exception: Follow Actions in Ableton Live.)
Al-Jazari requires movement only to tiles with adjacent edges. reacTogon, since it tiles hexagons, has six adjacent tiles instead of four. It can also map a harmonic table, as other musical hexagonal grids do. Now, that’s not to say reacTogon is better than the other – on the contrary, it demonstrates that just one choice – a grid of squares or a grid of hexagons – can create very different musical possibilities. So even if you’re not musically impressed by these examples just yet, think about the possibilities here. We’re still early in software design and musical interface, so early that something as simple as a simple geometric pattern can become an entire composition.
That’s something to ponder on the eve of the music manufacturers’ trade show.
(If anyone has more documentation on Mark or his creation, let me know.)
The idea of the Reactable is to make music tangible, with control of sound mapped to physical objects you move around on a table. But that hasn’t stopped the Psychosynth from creating a virtual version. (Upside: it’s a lot more portable.)
Watch the video, but they seem to have made the opening minutes as dull as possible to thin out the non-believers. Skip past the generation of the white noise oscillator (wow, white noise!), and somewhere around halfway through, it becomes laugh-out-loud funny, with trance-style vocals about freeing your mind with free software. (Seriously – it’s awesome.)
While it’s in alpha stage, the software is fully free and open source (binaries available for Debian and OpenSUSE) – and that means this could be a good project to snoop around in or code through, those of you who are eager hackers.
At its heart, it’s simply an interactive modular synth inspired by Reactable. Drag objects around and connect them to make sounds and patterns. Underneath is a powerful C++ synth library, a 3D synth, and even a server version – so even if you aren’t sold on this interface, there are pieces here that could be useful. It’s all virtual now, but that’s not to say you couldn’t add input; support for the input library is planned later.
That said, I don’t think they went far enough with the virtual thing. Next, why not simulate virtual players for the virtual Reactable inside the computer. They could even behave like Sims, requiring regular stimulation and bathroom breaks. Eventually, you could unlock Bjork.
Enjoy. If anyone gets this up and running even in alpha state, let us know.
Across series of colored bars, sounds warp and mutate. Vines entangle as organic threads of music. Fingers and objects traverse sonic landscapes in surprising, mysterious ways. Welcome to the worlds of BricK, the musical table interface by Jordan Hochenbaum and Owen Vallis, which, charged with software by Dimitri Diakopoulos, Jim Murphy, and Memo Akten, explores new musical frontiers. The tool uses a combination of open source tools for tracking fingers and objects on a table, then feeds those into sound and music environments.
Just following the landmark, long-awaited release of Processing 1.0, BricK demonstrates the expressive potential of the open-source platform. Processing allows quick and elegant development of stunning visual interfaces, while other tools (ChucK and Reaktor, for instance) serve as sonic engines. Sometimes the sounds themselves are not revolutionary, but by simply replacing the visuals and interaction – just as with changing the look of a score – the music is transformed, too. (At top: experiments with different interfaces for music using the platform they’ve built.)
CDM got to talk to Owen and Jordan about the projects. And now’s a perfect time – the gorgeous Roots is looking for a home, in case we have any curators / galleries / other interested parties in our audience. First, a review of what these platforms are:
