AD1 is on track 6.
AD2 is on track 7.
AD1 is playing through track 7, but using the midi from 6.
AD2 is doing nothing. The midi on 7 (from AD2) is doing nothing.
Something happened with the updates in AD is all I can think of. I'll delete both and re-do them entirely and see what happens.
Deleting them, and replacing them works. Now to try and save the midi I made in AD2 originally...This isn't important. Just trying to learn something for later when it may be important.
