I had this happen every now and then in Cubase 12 only (12.0.52) and there aren’t really steps that can reproduce this problem. It just happens out of nowhere from time to time.
- Arm a track
- Hit record and start playing
- It will record into another instrument track that you worked on before but not in the current armed track.
What I want to happen: record the midi in that track I have armed, not that other track where it doesn’t belong.
