That sounds very interesting. I'm just now getting into talking with 
profs on my campus about GUI development. Mainly, I'm inexperienced, but 
more than willing to learn how to do stuff. I'll finish my last 
programming class (the most advanced available at this university... 
which actually isn't all that advanced) this semester, so rather than 
let the info rot from want of use, I want to play with creating stuff 
like GUI's. I'll chat with them about this then, and see if we could 
work something out. It'd be interesting to see what they say about the 
difficulty. I like the idea, and as you said... it would be rather well 
used. *shrug* We'll see. Any suggestions on a language I would want to 
put forth for this (RUBY, Python, etc.). And thanks for the idea.


P.S. I'm also from the windows crowd, but I used FLStudio. Mainly 
because I just can't find the time to learn CSound yet. I'm dead in love 
with algorithms, so if anyone has any cool sites on methods of 
programming synths in CSound, I wouldn't mind at all you sharing it with 
me. That said, I do google a good bit, so no worries if it's something 
that's easy to search for. Otherwise, I'd love to see what you people 
could throw at me.
