I transfer all my BIAB tracks as WAV files to a Digitech JamMan Solo XT looper pedal. I am able to store them as single files and not loops

I then use a DigiTech FS3X 3-Button Footswitch to scroll through the various tracks and to start and stop.

I'm able to do everything by the use of the foot switch, which I think makes it less obvious to my audience.

The pedal is connected to my Bose LI.

That's my way to do it, but I know there are many more that folks on this forum have had success with.
