I am in the same boat as the original poster. I have the Alesis USB pro kit and Superior Drummer, but the Alesis kit doesnt output Aftertouch, and right now, when I hit the Choke Strip, it plays a hit which then chokes itself after a certain amount of time. I’d like to be able to decide when to choke a hit.
Is there anywhere I can find instruction on how to assign a note to the Envelope Note-On function, so that when I hit that Choke strip, it outputs a certain note, which Superior Drummer interprets and silences the appropriate cymbal?
