Sometimes if I like a few notes at the beginning of an Intro, I can keep playing those few notes (usually a short drum pattern) over and over by just repeatedly pressing INTRO to have it cut off the full intro and repeat the first few notes over and over.

Or, sometimes I try to get the transitional fillin without actually going to the other part. For example, I'm in Main B. I press Main A (to get the B-A transition) and then very quickly press Main B again so only the B-A fillin plays and Main A does not play. Thus: Main B, B-A, Main B.

  Another nice "trick" is to start a song with the ENDING! You then hit Main just before the song actually ends so there is no "stop", or just use part of the beginning of the ending by hitting the Main "prematurely" near the very beginning of the END to just get a few notes of it.

Of course, if you actually let the END "play out" when you are recording you will truly E-N-D the recording -- so you have to be careful with this one.
