Damn, I think you cracked it MIDI Jedi master !
It needed to have a midi track with that specific channel (6) assigned to it to be able to pass it to the midi out, even if it’s not for recording anything on.
The Triton > nord drum always worked because I had a midi channel 7 setup by default in my template !
I’ve just gone and ordered a MIDI4+ as well, but it will be useful anyhows.
Many thanks SoundRider
