I have, say, a 16 bar tune and want 1-8 to loop twice, then have 9 - 16 loop twice, then have 1 - 16 play through one more time with no looping.
How can I do this?

Will I be able to then save this "arrangement" to play back later?

I did a search in forums for "looping" and checked posts but no answer specifically.
I also tried to follow the User Guide but so far no luck.
