Updated and forgot to save something. I’d figured it out before but now am at a loss. None of these main fader/encoder settings seem to work properly for me anymore other than the open state master fader which moves the master fader on the mixing console, and the open state master encoder which does the same for pan.
At one time I could hold one of the pads (shift/ctrl/alt/fn) and move this.
I can’t remember if it was the default or I changed something but it used to work.
From what I can tell from the API info provided this should be working as you’ve supplied it if I simply hold the Fn pad. Correct?
