Using a Kontrol S-Series MK3 Keyboard with a Maschine MK3 or Maschine+
It is possible to use this combination of devices accessibly, given the following conditions:
You must have a Maschine MK3 or Maschine+ connected to your computer as well as your Kontrol keyboard (plugging the Kontrol keyboard’s USB connection directly into the Maschine’s USB Host port is not supported by the Accessibility Helper).
You are running version 3.3 of the Maschine software.
The Accessibility Helper application will report messages from whichever you enabled Accessibility Mode on last. All that you need to do to switch device is is:
Hold down the Shift Button on whichever device you wish to use
Press the DAW Button (for Kontrol) or the Play Button (for Maschine).
