Confirmed, (well almost)
I froze the MIDI track, then added notes, then regenerated and the added notes were included in the playback.
My expectation would be that I shouldn't be able to add notes to a frozen track, or that those notes should not have been included after regeneration.

I didn't get a message about tracks exceeding capacity.

I'll see what the developers suggest.
