TRAKTOR S8 KONTROL
MACBOOC AIR
I CANT INSTALL MY DJAY PRO

Please note that the NI Traktor Kontrol S8 is NOT natively supported by djay Pro. However, you can map any controller yourself, using our MIDI-Learn feature. How to do this? You can’t find a full description here (don’t worry, it’s a really straightforward process):

Just make sure to switch the S8 into MIDI Mode.

Can you do that on the trial version also, want to see how it works before purchaing.
