This is bizarre but it’s happened to me a few times with Cubase (Maybe as far back as version 6.0)
Here is the description:
-Record MIDI on a particular instance of Kontakt
-Audio plays, and the orange midi activity indicator is illuminated during recording
-Solo the track
-Track plays back fine
-Un solo and then playback. No audio. No orange midi activity indicator.
-If you click on a midi note, the instance will play, but otherwise during playback the track is silent with no midi activity, despite there being midi content inside the piano roll.
If I return the instrument to SOLO state it works fine again.
Duplicating the track will result in a new track with the same issue. The only solution I found was to make a NEW instance of Kontakt, reload the instrument, and copy paste the midi on to the new track.
Since the midi part itself still functions when copied elsewhere, maybe this is an internal crash of that particular Kontakt instance?
Any ideas? thanks.
