Midi mapping works but doesn't function


New member
Ableton 10 user, I can map midi cc to the functions I want but when I exit midi mapping mode the buttons I assigned don't work. I have remote enabled in preferences, I can see the midi in indicator working. Midi channels are ok.

My midi controller is a yamaha mfco6, yes it is pretty old but if Ableton recognises it and is able to map it, shouldn't it work fine?

Any help is appreciated.
