Sorry to keep posting, but I keep coming up with more questions that don't seem to have answers anywhere that I search. Basically, when playing back an internal song on the PX's memory, it goes back to the beginning and starts it up again instead of just finishing and being done with it. Is there a setting I can adjust to just make it play through once? I have scoured the manual to no avail and have searched everywhere I can think of to look for an answer before inundating this board yet again. Thanks once more.
