Had a thought on whether it was possible to use the BB to play .wav backing tracks.
If a larger wav file could be stored in a song e.g. In the accent field so it could be triggered by accent footswitch it could allow the pedal to hold a number of backing tracks as a set giving the pedal a dual purpose for a performer. The folder and menu system lends it self to creating set lists based on backing tracks. Just an idea.
