Mixxx – Free 4 Deck Dj Software

Powerful Features For All DJs

Mixxx integrates the tools DJs need to perform creative live mixes with digital music files.
Whether you are a new DJ with just a laptop or an experienced turntablist, Mixxx can support your style and techniques of mixing.

BPM, KEY DETECTION & SYNC

BPM and musical key detection help you find the perfect next track from your library. Use Sync Lock to match the tempo and beats of four songs for seamless mixing.

DJ CONTROLLER SUPPORT

Built-in mappings for DJ controller hardware gives you hands-on control of Mixxx’s features. Use the programmable mapping system to customize your workflow and add support for any MIDI or HID device.

EFFECTS

Add your unique spin to tracks with sound effects. Get creative by chaining multiple effects together and twisting all their knobs.

VINYL RECORD CONTROL

Use turntables with timecode vinyl records to control playback and scratch your digital music files as if they were pressed on vinyl. Mix music vinyls into your set by toggling vinyl passthrough mode.

FOUR DECKS

Drop a song onto a deck in Mixxx to start playing right away. Keep your eye on beats and cue points with a scratchable, scrolling waveform together with a whole-song overview waveform for quick seeking.

PITCH AND KEY CONTROL

Change the tempo of songs without changing their pitch with keylock, or change the pitch without breaking sync so your songs play in harmony. Temporarily nudge the tempo faster or slower for manual beatmatching, with smooth changes in pitch just like vinyl.

BEAT LOOPING

Need to extend your mix while you bring in the next track? Instantly loop a 4, 8, or 16 beat segment with ease. Save loops to hotcue slots for complex re-arrangements.

SYNC LOCK

Engage Sync Lock on your decks and they’ll stay locked in time even if you change speed. Construct remixes on the fly with multiple tracks and loops without losing control. Pick which deck you want to be Sync Leader or let Mixxx choose it for you.

HOTCUES

Set hotcues to mark places in tracks. Remix and mash up tracks with accurate, rapid-fire hotcue triggering.

BEAT ROLLS AND CENSOR

Play with rhythm by triggering short loops and reverse-playback effects. The track stays in time so you don’t miss a beat.

QUANTIZATION

Mark and activate cue points and loops exactly on beat every time.

BROAD FORMAT SUPPORT

Compatible with music files in lossless FLAC, WAV, and AIFF formats as well as lossy MP3, M4A/AAC, Ogg Vorbis, and Opus formats.

EQ AND CROSSFADER CONTROL

Choose between multiple equalizers and isolators with adjustable shelves. Crossfader curve control lets you deliver quick cuts or long, smooth crossfades.
