Hello. Is there a way to use an envelope on a MIDI track to control the overall velocity of drums coming from a plug-in? I'm using Superior Drummer 3 as a plug-in and I'm dragging grooves to my Acid Pro 11 timeline. I'd like to use an envelope to control the overall velocity of the drums to mimic a drummer fading in. Is this possible? Also, when I lower the track volume of the MIDI track it doesn't affect the Superior Drummer 3's levels. Am I missing something?
