Install CMK Config software to program your Classic Keyboards.
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.
If you wish to set up the keyboards for use with Hauptwerk, and do not need customized MIDI messages on the pistons, it is much faster and easier to use the "Quick Set-Up Tutorial" than CMK config Software. If you simply need to turn functions on or off or to change channels, please check out the "Programming Individual Functions with Pistons and Keys" tutorial.
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.
