I want to assign the large rotary knob under the display of my Keylab Essentials 49, to send Program change messages to external hardware - e.g. a Digitone
In the Midi Control Center, I can select only specific buttons and assign a program change to them, but I want to use the rotary knob. It won't even select - i.e. it's not programmable?
The action I want is really simple but I cannot find a way to do it.
Any help appreciated
