Jonas and I have been making music together for a long time (he and Josh Bothun were the friends that introduced me to music software (Fruity Loops), about 10 years ago!). He can be heard playing flute in some other things I've done, for instance "Music for Games", which can be downloaded here (and which I sample here).
This is a video of me playing a piece of software for 2 hands (1 or 2 players) that I wrote a couple months ago. It's exploring ideas that are similar to those in ada, the "album" of interactive music pieces I made with Josh Bothun (and available for free download at that link).
You can play a stripped-down version online here (unfortunately no sound unless you download SuperCollider, and set a few things up yourself--Let me know if you're interested in doing that, and I'll get you on track :)).
