This is where I wonder if I’m making a mistake.
I would’ve thought MIDI channel 9 on Ableton would correlate to Track 9 (‘MIDI A’) on the Digitakt. MIDI Channel 9 on the Digitakt, for example, is outputting on Midi Channel 1 to my JU-06A (as per SRC tab, I think it is).
Is there where I’m getting mixed up, and perhaps I need to switch something on the Digitakt for MIDI A (Channel 9) for it to register as Channel 9 on Ableton? Perhaps in a similar way that you need to press Func and click the dial to select the MIDI channel you are using on the digitakt for the outboard gear.
