Dorico 5.1 does not record but playback is just fine

It used to work and now it doesn’t. I made sure that all MIDI devices are recognized and checked. When I start recording I hear the metronome click, the VST Instrument and the position pointer moves, but after stopping nothing is recorded. Also when ctrl+ALT+R is pressed, the notes appear on the screen.

I’m not sure what the reason is, but after I removed one of the 2 MIDI keyboards, Dorico worked as expected. Maybe the one keyboard is sending weird MIDI data?

Hi @arnoldsz , that may well be that one of your keyboards sends weird data. In the Dorico preferences on the Play tab is also a switch where you can tell Dorico to filter out MIDI control messages. What if you try that out?
