The Reactable has been translated for multi-touch iOS devices! The demo below shows it in action. The music in the demo may or may not be to your liking, but the user interaction with the instrument is nothing short of amazing IMHO. Watch at least a couple of minutes to see the interactions with the oscillator waveforms, ADSR envelopes, etc. Really the stuff of the future.
