If I am understanding these new tracks I can paste audio onto them or paste MIDI onto them.

1) What happens when I regenerate? I assume nothing changes on the editable utility tracks?

2) What happens to the audio on the editable utility tracks if I change key? I am guessing nothing?

3) What happens to the audio on the editable utility tracks if I add bars to my song? Does it just add blank space to the end?

4) What happens to the audio on the editable utility tracks if I insert bars into my song? Does it insert blank space equivalent to the inserted bars in the proper place in the utility track?

5) Related to #4 above, what happens in the following example,
- generate 24 bar song with one chorus
- copy generated audio on one RealTrack to a utility track
- insert 4 bars at bar #5
- does the audio on the utility track get split with space or remain unchanged or something else?
