Currently the sequencer allows one timeline looping region. If it allowed unlimited timeline looping regions instead of just one it would really help sequenced arrangement performers. When I perform a sequenced arrangement I almost always want the record loop to repeat until I exit it explicitly (via foot controller). This makes everything more dynamic for multiple reasons: it allows me to let some time pass while I pick up the next instrument while all active tracks loop; play through the section more than once while just keeping the last cycle; remember what I'm supposed to be playing on this section!; just let it groove an indefinite number of times before proceeding.
