CMK Config Software for your Classic Keyboards
Install CMK Config software to program your Classic Keyboards.
CMK-3B
If the back of your keyboards looks like either photo below - with a USB port on the back - then you should download Version 3.43 for PC or Mac. All version 3s will work with both CMK-3x and CMK-2A keyboards. It will work with them in a mixed stack or unified stack. It will also work with the new 24-piston versions, alone or in a mixed stack.
If you wish to set up the keyboards for use with Hauptwerk please take a look at the CMK config manual (click here to view). If you wish to set the MIDI channels on each of the keyboard, scroll down to the bottom of the manual and look at the steps under Quick Config for Hauptwerk.
If you need to program custom messages, or have pistonless keyboards, you will need to download CMK Config.
For information about how to connect a stack of CMK keyboards to a PC or Laptop, so you can use CMKConfig, see the support page: Connecting CMK3 keyboards.
