Is it correct that the M32 "4D encoder" doesn't send a (midi) message when you push it (confirmation) in midi mode?
It does send midi messages for the other functions (turning or tilting) in midi mode. The 4D encoder works OK in DAW mode or with the Komplete Kontrol 3.5 software. As far as I know it is not possible to make a midi template to assign the midi messages the 4D encoder sends.
