I just updated computers (new Windows 10 PC), installed Cubase 12 and went to load one of my sessions from my previous system. Weirdly about half the instruments don’t play. When I look at an instrument VST (Kontakt for example) I see the MIDI being triggered and the output meter within Kontakt lighting up. But that output doesn’t reach Cubase for some reason. If I create a new instrument track, I’m able to load and hear the same patch no problem.
MIDI is working. Sound settings match Cubase. Memory isn’t an issue. I tried changing routing settings to see if that did anything, but didn’t.
Appreciate the help!
