I've had MMV for a while now and I finally got myself a respectable MIDI controller. Part of the reason I wanted a better controller is so I could change patches just by using one of the program change buttons, and it does that. however, it only changes between a handfull of factory preset sounds and the manual doesn't seem to know a way to change this. First of all, is it possible to assign different patches to different buttons, and if it is, how? Thanks, and sorry for the newbie question.
