Kontrol S MK3 can be used with Maschine as a regular MIDI controller. This means that while you can play your plug-in synthesizers and instruments with your Kontrol S MK3 in Maschine via MIDI and use MIDI CC, there is no advanced integration such as transport control, scene change, etc. at this time.
We are investigating opportunities to extend this over time as we evaluate overall improvements to the product experience that benefit the majority of customers.
