Hi Frank,

Just Curious, why don't you play styles from the BK7 on your left hand in real time and use natural accordion voices?? I do that quite often!

But if you want to play backing tracks, it seems to me that the BK7 wouldn't take up any more room or weigh any more than a laptop. You still have to have a sound system of some sort. You can start and stop the wav files via foot pedal on the BK7.
