I have the BB and I also have the two button footswitch. A month ago I downloaded the “Most popular cover songs Vol. 2” and the pedal worked great. Tonight I purchased “Most popular cover songs Vol. 1” loaded the songs on the pedal and now no songs will transition from part 1 to the next or insert any fills except for the pre-loaded songs that came on the pedal. I’ve tried unplugging the external footswitch and using the main pedal only and that does not work either. Has anyone else experienced this and if so can you please share how you fixed it? Thanks!
