Sorrry i don'y mean you can turn off the smoothing. if a slider is in one position and you mute the midi it then move it to another postion (value). Then when you umute it the midi signal will change from one value straight to another not in increments so the change would be instant (providing this would not have too much lag). Thats me idea but i havent't bout a controller yet so can't try it.
Another question is where can i get information about Supatrigga and could someone tell me if it is stable when used as a plug in for live.
