Based upon a reply to a previous post, I set up the looper as a preset so that I could call it up through midi. It records, plays, and stops but I can't figure out how to empty the loop via midi. I have Fs1, fs2, and fs3 assigned cc's. Pressing buttons fs2 and fs3 on my midi foot controller toggles the TF in to play mode (which probably means the TF is receiving one midi message but not the other) but doesn't empty the loop. What midi message can I send to the TF to empty the loop?
