Maybe I missed it, but I think it also needs a way to have it progress through the song's REGULAR structure if you don't alter it. Currently it seems to loop each section endlessly and it's up to you to trigger the sections correctly (again, probably difficult to remember for a large songlist).

On a jam track, not a big deal, but on a more structured song, it's going to take precision to remember to trigger each section sequentially. Again, something Ableton etc do automatically until you instruct them otherwise.

Forgive me if I missed you explaining how to do that. But I think that's it's most likely use scenario, a linear song that you can override when you want to...
