Random MIDI note transpose while playback

Cubase
1

Hey guys,

since V13 it happens, that on a Midi track with a VSTi, while playback, Cubase just transpose notes randomly (only every few minutes and just one hit).

I can’t reproduce it in a new project - but it happened in several projects now while working. (seems like there has to be more going on in the project to trigger the issue).

Step Designer - adding notes
Chorder - add chord

Same problem here.
Did you find the solution already? I would like to know.

Sadly no. It’s still happening with the latest update. Not very often, but it did ruin some record sessions, I did. Very annoying. Not sure if it has something to do with the MIDI plugins, but I know it also happens, when they are turned off. But it happens mostly on tracks, where I used them.
