Hi,
When you hit a button when mapping it will only work one time to assign the control and make a new red control next to it.
After you assign it go to the mapping control. Select the control function and hit assign. Make sure it is set to takeover and toggle or whatever (at the bottom of the mapping page).
If you can’t assign a button control that way you will probably need a script
For MMC I think it will still work as long as the keyboard’s button command is assigned MMC.
I made this for my MPK mini. Everything had to be assigned to a CC. My CC control button has to be enabled on the MPK.
I hope this works for you.
