I select the track I want a midi loop to appear on. If it is a bundled Cubasis 3 midi file, it appears correctly on the selected track as expected. If it is a third party midi file I have imported, a new track is created automatically and the loop placed there, not on the selected track. If I then try to bring another external loop into the project, another track is created and the loop placed there. And so on.
Also, autoplay preview doesn’t seem to work on third party loops.
