I've searched but not found a clear answer to this. I want to use a midi pedal to just change the folders on my M9, then use the M9 switches to select a scene from within that folder. In essence, the midi pedal becomes my "Bank up/Bank down" switch. I can't get it to work correctly. It gets "stuck" on a particular folder and the M9 switches usually choose scenes from the folder that I just left. Is there a trick for this, or is it just not possible?
