we use a couple of uTrack24 for our show playback backing track and a midi file with PC and CC. Before use the UT24 we used Lp-16. The playback and sync of midi was with any issue.
Now we use the same files (midi and audio) and the playback of MIDI was about 500 msec in advance compared to audio!. And no, the MIDI offset in the UT was set to 0 millisec… 🙁
