This tells Traktor what to do when you move a physical control.

Traktor Pro 3 is renowned for its flexibility, largely thanks to its powerful MIDI mapping engine. Whether you want to repurpose a button on a Native Instruments controller or integrate a third-party device like a Novation Launchpad or Akai MPC, mastering MIDI mapping allows you to tailor the software to your specific performance style. Getting Started with the Controller Manager

The Controller Manager is the central hub for all mapping activities.

This enables visual feedback, such as making a button light up when a Track is playing or a Hotcue is set.
