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
http://digitech.com/en-US/products/jamman-solo-xtI 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.
