Sold my Korg M1 about a year ago, but really miss having a keyboard. I have an 88 key M-audio controller, so I just got this:
It's like having 2 keyboards plus a shitload of expansion cards. Something like 4000 sounds. Pretty fun to mess around with, and at $150 I just couldn't pass it up.
Talk to Vince, I'm pretty sure he's way into that stuff as well. IIRC, all of the drums on SITA were done with that controller.
