I have a similar situation occurring with the first track...

I usually put my MIDI tracks at the beginning of a project, but I've noticed that sometimes (not always, but a lot) the first track will get converted to an audio track, and I can't change it back to a MIDI track because "it has data in it"

Usually, the MIDI track only has patch change and a few continuous controller commands being sent to a device, so it's not too hard to recreate it.. but sometimes the track has a lot of note data that is not easy to recreate. When that happens, it's a pain.

My workaround is to put a dummy audio track in track one of every project so nothing I need gets changed. This has been happening for at least a few years.


FWIW, I have also experienced the first track being converted from a stereo track to mono. I've noticed it usually happens after using the Audio Chord Wizard
