To open the MIDI CC assignment view click the CC button in the top bar. There are no preset CC assignments.
To assign a MIDI controller to a parameter on M-Tron Pro IV, click on the corresponding text box on the parameter you wish to control. The dashes will go blue to indicate it’s ready to assign. Now move the physical knob or slider on your MIDI controller to assign it to that parameter. The CC number of that controller will fill the box.
Independent layer controls have two colour coded boxes per parameter. The top green box is for layer A and the red is for layer B. If you wish to control both layers please assign each to the same CC number individually.
Double-click a assigned CC box to clear it. Or click the Clear button in the top bar to clear all assignments at once.
