So far, I created a midi track in Cubasis and selected Thumbjam as the midi-out. In Thumbjam under MIDI Input connections I've selected Cubasis and clicked the Voice Input button. When I play the keyboard in Cubasis, I'm still hearing a Cubasis instrument and not the instrument loaded in Thumbjam. I've tried specifying a specific Cubasis midi-out and Thumbjam midi-in channel rather than "All", but I get the same result.
I notice the Cubasis manual mentions a "Midi-Out Active" setting, but I don't see that in the app itself.
Any help appreciated!
