Well...
Admittedly, I'm no Einstein with this midi stuff but I'm not bright enough to envision how that would work.
I was under the impression one still had to have a keyboard controller for BIAB to speak to in order for midi messages/patches to play at all.
I'm no help but look forward to the responses you get to understand how that's actually accomplished.
Me.....I have (3) modules (Proteus FX, Roland MBD-1, Roland MVS-1) triggered by my Monoprice controller.
Back to it.....
