TRAKTOR PRO 3 can be used with any MIDI controller. If you want to integrate a controller, you have three options.

We build compatibility for many “TRAKTOR-ready” third-party controllers. This means you can plug in, select your controller in TRAKTOR, and get into the mix right away.
ALL TRAKTOR READY CONTROLLERS

If you’re using a controller that isn’t “TRAKTOR ready', you can often find pre-configured MIDI mappings (.tsi files) on the manufacturer's website, or by searching the web. If not, you can create your own MIDI map for any controller by using the controller manager in TRAKTOR’s preferences via the MIDI learn mode. MIDI maps can be saved for future use.
