In the past, I created some performances for my BK-9 based on user styles that had certain rhythm tracks muted. If I play a song using one of these performances, and then subsequently select a DIFFERENT performance that's based on a factory style, all of the tracks don't play. Because the mixer settings carry over from my first performance, some of the style tracks remain muted.

I know that I can open the mixer window and manually unmute the style tracks one by one. But is there a shortcut to unmute all of them with a single button press? Or perhaps I need to release some kind of lock, so that when I select the second performance, the track mute status defaults to what's programmed in the newly-selected performance (i.e., all tracks unmuted)?

I know that I could go back, edit my custom performances, and simply delete the musical content from the muted tracks. Then I could unmute the now-empty tracks, and re-save the performance, thereby eliminating the source of the problem. But that would be a tedious task. I can't help but think that there's a more streamlined way to prevent this unwanted interaction, taking advantage of the built-in settings.

My fellow Roland BK users, have you ever encountered this issue? If so, how did you deal with it??
