this is utterly amazing. whoever the programmer is, holler at me, I'd love to help you make it a collaborative realtime beat-making engine, i.e. so people can contribute to the same song at the same time. I'm sure you've already thought about this. It's about time for a javascript collaborative beat-making engine to take off, especially with midi support on the horizon or here already (i forget).
I wish someone would bring back the greatness of real-time music sharing from Turntable.fm, except maybe with instruments you could pick up and jam with. Maybe each person gets 1-2 loops, and 4-5 people get to be up on stage at once. Everyone else just gets little avatars that party.
Full real-time collaboration would be so annoying with various latencies. Would be super difficult to set up, but I've always wanted a way to do something like that too.
