Re: making apple loops follow the chord prog of the so...
IF the loop is a Software Instrument, i.e. green MIDI track, with the track editor open in either Score or Piano Roll format, you could highlight all the notes in the loop, starting where you want the chord change, and transpose-by-dragging the notes (which will all move as a group) up or down to the desired beginning note.
If the loop is a blue/Real Instrument, I guess the pitch slider is all you've got.
Regarding going to sevenths, there is a point beyond which the loop library can't help you, and this is one of those. You're gonna have to limber up the fingers and play..
