Hi guys, same kind of problem here...
I have the mkII up to date, working in DAW mode with logic pro 10.6.2. I can't assign any fader to automation quick access, bu I can assign a knob without any issues... Very weird !
I tried reinstalling Logic, same with the MkII, looking in the preferences, deleting the old files in the user library... It seems that a conflict between midi signals is occuring but I can't figure how to solve this...
Thanks for your help !
