I\'m thinking about getting a MIDI controller. Right now I have a Kurzweil 2000, but the only controls on it are 1 slider, a mod wheel, and a pitch wheel.

One thing I\'d like is to be able to assign buttons to change the MIDI channel I\'m playing on so that at the hit of a button I can change from say channel 1 to channel 3 as I play. This would be cool for accessing other articulations of an instrument as I play a phrase. The Evolution UC-33e seems to be the most programmable. Anybody here own one? Any other suggestions?
