When I press the those two buttons the play one key of the keyboard. I reinstalled the complete suite Native Instrument and I have the updated firmware for the keyboard. Any suggestion?
Rec and Play are for DAW control - when using KK inside your recording software like Studio One for example. OR for use in Maschine etc.
Can't imagine how these buttons would have purpose (especially record) in KK Standalone.

Sorry, you are right; same behavior when KK used as plugin in Logic Pro.
If Rec and Play are not working in Logic (and I know they should) that is a possible issue with your KK drivers, or possibly the KK hardware integration services.
