These actually don't sound too hard.  Prediction:  Mike will whip this off
for you in a real short time...in exchange for you echo/reverb/reverse
effects code.
But just in case he can't do it because he's too busy, I'd be willing to
give it a shot, even though I know less about the Mac stuff than he.

Actually, it's pretty fun once you get started.  :-)
