If it’s not clear - I’m sending midi to my laptop which looks at the notes and sends them back to DT via USB…
you’ll need something which takes notes as input, and dynamically modifies the channel so it targets the right tracks in output… there are midi gizmos which do that I think, the midipal probably?
Control-All works fine if you wanna tweak all 8 tracks. You cannot choose individual tracks to be included in the control-all thing tho… software can help there too, if you wanna set it up in a way that e.g. only tracks 4-8 should be polyphonic…
