Cubase sees my MIDI keyboard but won't play VST in real time

I have Cubase 10.5.30 and suddenly my nanoKEY2 external midi keyboard can’t play any VST3 in real time. There’s midi in activity, and it can record notes on a track, but I can’t monitor the midi notes I’m playing.

Thanks and regards


Can yo see the MIDI activity in the instrument (if there is any MIDI “led” or meters, or something like this)? Can yo see the meters on the Instrument track?

Have you tried to increase the Buffer Size?

there wasn’t activity on the instrument. Now I solved the problem, I’m not quite sure how, but it has something to do with preferences_ MIDI_MIDI filter. Regards


I see, the MIDI Notes were probably filtered out for the Thru column in the mentioned preferences.

yes, most likely
