This is definitely a cool idea guys...I actually did my thesis connecting Music (composition) and Architecture, so this is really up my alley. Although the "sound as form" kind of thing its definitely cool, I'm personally, I'm way more about the actual notes and those kind of musical structures and what's going on. Anyway, I did a little searching on MSDN and there's a Midi module within the dotNet framework. So, I think I'm gonna start looking into possibly connecting this through more of a composition/notes basis. This is definitely gonna come up with some cool stuff and I'm really wondering what's going to come out of it. Keep experimenting cause this stuff is already pretty darn sweet.
