On a Juno DS-88 I save a loop of bass drum and rim-shot rhythm and can replay it fine. If I play that loop and then switch to piano to play along with the loop, the loop keeps playing but the bass drum and rim-shot voicings change to the corresponding piano key notes, or whatever instrument I am trying to play along with the loop, so it is useless for making a backing track and playing along with. Any way to get saved loop to stay exactly as saved? Thanks in advance!
