A "mapping" (or "MIDI mapping") is an XML or script-based configuration file that tells Virtual DJ how to interpret signals from the controller’s buttons, knobs, faders, and jog wheels.
Unlike some DJ software that locks users into proprietary hardware ecosystems, Virtual DJ prides itself on flexibility. It communicates with controllers using MIDI (Musical Instrument Digital Interface) or HID (Human Interface Device) protocols. The Mixtrack Platinum FX sends MIDI signals; a mapping file acts as a translator. It assigns every physical control—from the crossfader to the FX paddles—to a specific software parameter. numark mixtrack platinum fx virtual dj mapping download top
