As computer music practice – part composition, part instrumental play – spreads, the idea of software interface as performance tool is becoming second nature. Putting those opposable thumbs and sensitive fingertips to work, multitouch controllers are growing in number, variety, and sophistication. Berlin-based artist Marco Kuhn shows off his beautiful creation, the PlayBox multitouch hardware, and its first app, PlayLive. That first software focuses on Ableton Live performance, but Live could be just the beginning – Marco has worked with Pd in the past and promises other apps to come. He’s interested in selling this device in the future, and he shares with us the tools he used to create this work for those of you doing development along similar lines.

The Project:
“Play Box” is is a User Interface for Natural User Interaction.

    • allows multi-touch and object recognition (TUIO marker)
    • hovering is also possible
    • 22 ” TFT display , 1680 x 1050 pixel
    • robust
    • plug`n play

“Play Live” is a dedicated multitouch controller surface for Ableton Live.

    • GUI Elements support multi-touch interaction
    • easy to setup , just load the “Play” Control Surface
    • you need no controller assignment
    • you can control 32 tracks and 127 scenes, that are 4064 clips
    • track controls are mute, solo, record, send1, send2, pan, level
    • scene feedback name and state
    • clip feedback color, name and state
    • Transport control
    • 2 Returns
    • Master
    • support bidirectional communication
    • display track level meter, name

The whole app is coded in python.

    • use Python Ableton Live API
    • and libavg www.libavg.de for the GUI and Trackingengine
    • PyPortMidi receive/send Midi Messages

“Play Live” Future plans:

    • FX View per Track
    • subpage for abstract clip controlling

I tested it with my mac book pro, “Play Live” and “Ableton Live” is running at the same machine. It should work on all platforms (Windows, Linux, Mac OS X). That Project started with my Diploma Thesis in Applied Computer Science 1 year ago.
Everything is coded and built by myself. The GUI – elements has been designed by Gösta Wellmer.
In this work, I created a GUI-Controller Library which allow me to Develop very rapidly Multitouch Interfaces for other Audio Environments.
More Apps coming soon ;-)
I [plan] to sell the” Play Box” and Apps like “Play Live” if anyone is interested.
The price is yet not specified.


That`s not my first multitouch Interface. 2 Years ago I created forfour http://forfour.hi-pi.de/ used PD, Processing, Reactivision and OGRE.


But the “Play Box” is another level;-)
