The Native Instruments Kontrol X1 is a controller built for use with Traktor Pro 2. It comes pre-mapped with the most important software controls so you can start mixing as soon as you plug it in. I personally use 2 X1s to control 4 decks and effects in Traktor Pro 2. Watch this video to learn more about the Native Instruments Kontrol X1.
Buy the Kontrol X1 on Amazon.
