I had a lot of trouble exporting a protools midi file for my LP16. But now it works !!!!!!
So I share my experience with you. I think it’s the same for the utrack24
It is necessary:
-Assigned to each track a channel.
-make at least one track tracker.
-delete the sending of MTC (midi time code)
-and the most important:
delete all the tracks that are not useful for the export of the midi file (all the empty midi tracks, all the audio track, all the bus tracks, all the master track, the click ….)
It is a bit constraining, so ideally create a session only for the midi export, but with all this, it works very well!
All the channels, the CC automations, the program changes work !!!
I hope this will help you…
