Sorry, but what is Midi page? I have opened an Event List for the track, but I can not find anything there. How did you locate the double notes?
Coping to another track did not help unfortunately...
I just marked, that Modo Bass sometimes doesn't play the existing note, but play some other long note instead. And it happens in different places. I have checked for the double notes in that place, but didn't find anything.
It is really annoying, since I can not Export my project as an MP3 File because of this bug...
