Midi plays back random sounds when record enable is on

See topic title. If I have record enable on midi tracks, they play back random sounds. This has never happened before and I don’t know what would cause it. This is happening mainly to midi drum tracks. For example, I have a snare track, but it is now randomly playing kicks, hats, toms and cymbals at the same time if record enable is on. If it’s off then everything’s fine.

Any ideas on what the reason is?


To me it sounds like some MIDI device sends the MIDI data in. Try to switch from All MIDI Inputs to other MIDI Input and find out, which MIDI Device sends the data.
