in other words, say I am playing a live set and I need the volume of a particular vst changed but I don't want to move a slider or turn a knob on my controller. I would rather just hit a pad (korg kontrol 49) and have it change on the spot and also change perfectly.
I was trying to do this but I only seemed to be able to have the volume change to either completely down or completely up.
I know, I know, basic midi question
