Native Instruments Traktor Pro 4.5.1.21

Traktor Pro

Native Instruments’ flagship four-deck DJ application for Mac — built for club mixing, live remixing, and hardware setups ranging from Traktor controllers to CDJs, DVS turntables, and custom MIDI rigs.

Traktor Pro 4 is a ground-up rewrite shaped by long-running DJ community feedback. You can run up to four decks in track, stem, or remix modes, switch customizable layouts for different venues, and lean on reliable sync, looping, hot cues, and beat jumps during performance. The library supports MP3, WAV, AIFF, FLAC, Ogg Vorbis, and non-DRM AAC, with playlists, favorites, and Beatport streaming integration for expanding beyond local files.

Creative and performance tools

Stem separation powered by iZotope RX technology lets you isolate drums, bass, instruments, and vocals with per-stem waveforms for muting, filtering, and effect work. Pattern Player adds percussion kits from well-known producers, while Ozone Maximizer brings iZotope mastering-style loudness control to the master bus. Flexible beatgrids follow tempo changes for disco, hip-hop, or live-feeling tracks without the sync artifacts some rivals introduce. Over 40 deck effects, mixer FX, modeled EQs, Flux Mode, and remix decks round out a workflow aimed at both preparation at home and high-pressure club sets.

Hardware, licensing, and this build

Traktor Pro 4 offers plug-and-play support for NI Traktor hardware, many club mixers and CDJs, DVS timecode vinyl, Ableton Link, and deep MIDI mapping. Activation runs through Native Access; an internet connection is required for download and activation, after which offline use is supported. On Mac, the vendor lists macOS 13, 14, or 15 with Intel Core i5 or Apple Silicon and 4 GB RAM minimum. Version 4.5.1.21 is a maintenance build in the 4.5.1 line that fixes layout-related effect stability issues introduced in earlier 4.4.x releases.
