Hi, I have just started using midi automation and ran into this issue as well. After the upgrade to Logic Pro X 10.5 it got better (Not 1h tracks) but the length is still wrong. Tested creating a single midi file (Format 0) with 2 PC messages 120bpm 10bars for 18s then when I import it to uTool it says 38s. If I export the same region as Format 1 uTool says 01:24.
Have tested a few midi automations and they seems to be in sync with the audio tracks but the total length is incorrect. Is it a bug in uTool or the export from Logic? It would be great if someone from Cymatic Audio (or RIEDEL) could have a look at this as Logic Pro X 10.5 is out there now and more users might run into the same issue.
