One quick (and perhaps dumb) question, Larry. If you erase track 1 to eliminate the lead or melody line, as you suggest, in order to play along, wouldn't the chord sequences you used still play? In other words, you would have to play along using the same song you recorded and in the same key, no? Or am I missing something in your suggestion? One of the things I would love to be able to do is keep the entire orchestrations and setup structure provided in a downloaded song, etc. but use my own right hand melodies and left hand chordings within that registration pattern. Would that work? Thanks.
