You are one step away from my problem sequencing the Opsix with a Digitone (though I thought of a solution to that one I’ve been meaning to test).
Unfortunately, I don’t think there’s any way to do this without additional hardware, but short of the issues in the above link, this setup works great. For the “global channel” problem, I have a Blokas MidiHub set up between the Opsix and the DN. That means:
- The Opsix is set to global channel 6 with local control off, and connected in both directions to the DN, also on channel 6.
- Playing notes on the Opsix keyboard sends notes on channel 6, but the MidiHub intercepts them and remaps them to channel 10 before they get to the DN.
- Because the notes came on channel 10, DN receives those as “current track” - so now I can use the Opsix keys to play internal DN tracks, or if I set the track to external MIDI (channel 6)…
- The notes that came in from the Opsix go back out on the channel it expects, completing the roundtrip without double-triggering, and the DN can send trigs the same way with no difference.
