@Danieldidit … I just solved that exact same issue with my Stop / Start configurations:
You’re looking for CC 43. 1 - CC 38.127
If you have the “Play” button send both of those commands, it will start up the recorded loops, and unmute any previously muted track at the same time. I had the exact same need to strip down the loop for a bridge, and then have the loop fire back up with nothing muted.
