I don’t exactly understand the question but will point out that there’s too many parameters on the prophet for MIDI, it requires NRPN’s. Seems like a relevant issue to your request.
Hi Troy
What I need to achieve is:
1) Passing through the setlistmaker PrgChange on Ch 16 for the Nord, plus
2) Playing the "B" level sounds on my Nord via rev2
That would only be possible by joining the rev out with the rev2 through data, as there is (obviously) only one "in" on the Nord. So for live performance MIDI commands, a soft through on the rev2 would quite desirable! Otherwise you need a "ton“ more MIDI cabling and routing. But I‘ve solved it for now by using a MIDI solutions merger, joining the rev2 out and through to one out for the Nord
