I recently bought Cubase 11 and found out that the SOLO DEFEAT button of the Audio track I’m using to hear my MIDI track does not work because the MASTER audio also gets muted when I solo the MIDI track.
Create a MIDI track
Create an audio track
select the MIDI track and solo it
SOLO DEFEAT the audio Track and Master track gets muted so no more MIDI!!
I had that problem in a few versions of Cubase and it was solved but it is back again I guess!
