I’ve recently acquired a synth and I’m having trouble with Cubase and MIDI Out.
The midi routing seems correct, as I’ve always done it with other synths, and when I select the midi track, it plays and I can see it on the audio track. Once I record some MIDI and hit PLAY, Cubase stops sending that midi to the synth. It’s only sounding when I play it through the controller.
The box shouldn’t be selected. If it is selected, the MIDI data is filtered out.
But if it’s project dependent, then it’s something else.
Could you post a Screenshot of the two projects (working and non-working) with the MIDI Track selected in the Project window and the Track name tab open?
