a3d747, that is a known bug and you don't need to reset parameters to fix it- you just need to make sure roll is set to re-trigger after you have finished inputing any of the other arpeggio modes into a beat.
Roger, to clarify my earlier bug report I was trying to start a playlist in reverse and the reverse light would stay on but not be reversed. Though that function is certainly not as important to me as the light properly representing the reverse status, which you said you would work on.
I also noticed there is no sample in slot 202 "bell crash" in my digital samples, and there is no content in the project "spud and stump"
