Hey Guys,
I just came across this older thread with a similar issue, namely not beiing able to mute one of the VST tracks via a MIDI command while playing live in a particular song on the fly.
My live set includes playback tracks and within a song I play a live keyboard/synth part on the fly (Roland A300 Pro, Cubase 8 Elements). I would like to switch inbetween a synth bass and an arpeggiator, which are both loaded in two different VST tracks (HalionSonic). As for now, I can switch inbetween the tracks with my controller (pad), but I can’t mute the VST I don’t want to be heard at the same time!
Any thoughts on how to mute the VST via my Controller, while playing through two (or more) VST instruments throughout the song?
I believe, there is a way in activating/deactivating one VST track when moving to the next VST track
… I would greatly appreciate some help in this matter 
Thanks in advance for all advice.
Cheers, K.
