I am using my OT with a Novation Launch Control XL. The OT controls my Buchla Easel. What I do is stack a number of loops with the midi sequencer.
If I want to play a melody over these loops on my Buchla, I have to turn the midi channel to ‘off’, so that the OT stops sending sequenced midi to the Buchla.
Is there a mapping possible from my Launch Control, that turns the midi channel from 1 to off? Maybe I am missing something, but I cannot find it in the mappings overview in the manual.
