Traktor Pro 4.5.1 — macOS

Traktor Pro is the DJ software for people who have moved past the basics and want control over every aspect of their mix. Version 4.5.1.21 runs on macOS 12 and later, and it gives you the deeper tools an experienced user actually reaches for.

Four virtual decks — Mix across four decks at once, not just the usual two. That opens up layered sets and longer transitions without constantly swapping tracks.

Deck types — Choose between Track, Stem, Remix, and Live Input decks depending on what you're working with. Each behaves differently, and you can switch to fit the moment.

Stem separation — Isolate vocals, drums, or melody from a full track. Useful for live edits and for building acapellas on the fly.

MIDI control — Map your own controller or use a Traktor Kontrol hardware unit. Custom mappings and user-defined keyboard shortcuts mean the software bends to your setup, not the other way around.

External audio interface — Route sound through your own interface for better latency and flexible monitoring.

Export — Record your set and save it as a WAV or AIFF file for a clean, lossless copy.

Reverse playback is there too, for the moments when a track needs to go backwards. Traktor Pro 4.5.1.21 doesn't add flashy new features; it refines the tools working DJs rely on.

Requires macOS 12 or later and runs on Apple Silicon and Intel Macs

Traktor Pro 4.5.1.21 is a native macOS application built by Native Instruments. It requires macOS 12 or later and runs on both Apple Silicon and Intel-based Macs. The interface is in English. Because it supports both ARM and x86 64-bit architectures, you can install it on an M-series Mac without Rosetta or on an older Intel machine with the same installer. The app is distributed as a standard disk image, so you open the downloaded DMG and run the normal installation procedure. No extra libraries or plugin hosts are required — it is a standalone application that manages everything internally.

For anyone keeping an older Intel MacBook around as a backup DJ machine, this version covers both architectures in one package, which simplifies keeping your gear consistent.

Common installation concerns answered before you start

Can I use Traktor Pro without a Native Instruments controller?

Yes. The software works with any MIDI controller you can map, with an external audio interface, or even with a standard DJ mixer connected to your Mac. The custom mapping system lets you assign any function to any knob, fader, or button on your hardware. If you prefer keyboard control, user-defined shortcuts cover the same ground. The Traktor Kontrol hardware is one option, but not a requirement.

Beatport streaming lets you pull tracks without downloading files

Traktor Pro includes Beatport streaming integration, so you can browse and load tracks from Beatport directly within the software without downloading files first. This is useful for gigs where you need to pull a request from a large catalog you do not own. Keep in mind that streaming depends on a stable internet connection during your set.

Can I record my mixes directly inside the software?

Yes. The built-in recording function exports your set as a WAV or AIFF file. Both formats are lossless, which gives you a clean master copy for later processing or archiving. You can also save ID3 tags to the exported files and import tags from your existing iTunes library to keep metadata organized.

How does stem separation work in practice?

You load a standard stereo track, and the software separates it into vocal, drum, bass, and melodic elements. Each stem can be muted, soloed, or processed independently while you mix. You do not need separate stem files — the separation happens on the fly from regular tracks in your library.

Four-deck layout and external audio support for working DJs

Working DJs with regular gigs — If you play sets at clubs, bars, or events, the four-deck layout and external audio interface support let you build layered transitions and keep a track queued on deck four while three decks are live. The ability to map custom shortcuts and MIDI assignments means you can set up your gear exactly as you prefer and not adapt to the software's defaults.

Remix and production-minded users — The Remix Deck type combined with stem separation turns Traktor Pro into a live remix tool. You can grab a vocal from one track, drop a drum loop from another, and route them through an external mixer or audio interface for hardware processing.

Beginners who want room to grow — You can start with two decks and basic track loading, then gradually use the extra decks, stem separation, and custom mappings as you learn. The software does not force you into advanced workflows on day one.

Users who keep a portable backup Mac — Because the app supports both Apple Silicon and Intel architectures, a single installer works on your main machine and a spare laptop. That matters when you need a reliable fallback at a gig.

Each deck slot can switch between Track, Stem, Remix, or Live Input modes

Four deck types per slot — Each of the four virtual decks can be set to Track, Stem, Remix, or Live Input mode independently. You are not locked into one deck type for the whole session. This means you could have a Stem Deck on channel one, a Remix Deck on channel two, a standard Track Deck on channel three, and a Live Input on channel four all at the same time.

Reverse playback — It is a simple toggle, but having reverse available per deck without stopping the track opens creative options for buildups and breakdowns.

Synchronization with other programs — Traktor Pro can send and receive OSC and MIDI Clock data, so it syncs with lighting software, visualizers, or other DJ applications running on the same network. This is not something every user needs, but if you run a show with coordinated visuals, it saves manual beatmatching between programs.

Custom layouts and elements — You can rearrange what appears on screen and hide panels you do not need during a set. Combined with custom keyboard shortcuts, you can strip the interface down to only the controls you actually touch.
