Mix by ZawebaMix your own music with beats that stay locked.
Two decks, locked beats, and a helper that knows what to play next. A two-deck DJ mixer for your own music: beat sync, key lock, EQ, loops, effects, recording and What next suggestions with reasons.
This version isn't signed for Windows yet: if SmartScreen warns you, choose More info › Run anyway. Why?

Mix by Zaweba is a two-deck DJ mixer for the music files you own, for home, parties and small gigs. Scrolling waveforms show both tracks with their beats, sync keeps them locked together, and key lock changes the tempo without changing the pitch. EQ, filters, loops, hot cues and effects are all there.
Its party trick is What next. It suggests tracks that will mix well with the one playing, by key, tempo and energy, and tells you why in plain words. It learns from what you've played after each track before. Record your set to MP3 or WAV and Mix writes the tracklist for you.
Who it's for
- Bedroom DJs learning to beatmatch
- Anyone doing the music at a party or small gig
- Music lovers who want to make mixes from their own collection
Good to know
- Works with your own music files only, not streaming services
- MIDI controllers work through Windows MIDI with a mapping editor and learn mode
- Headphone cue needs a second sound output, or splits one output left and right
Private by design
- Works offline, with no account and no adverts.
- Checks zaweba.com once a day for a newer version, sending only the app's name.
- Problem reports and feedback are sent only if you click Send.
Everything you need, nothing you don't.
Sync that stays locked
Tempo matched to the other deck and the beats phase-locked for as long as sync is on. Press play and it lands on the beat.
Key lock
Speed a track up or slow it down without it going higher or lower in pitch.
Proper mixer
Three-band EQ with kills, a one-knob filter, crossfader curves, a limiter, and auto-gain that matches loudness.
Hot cues and loops
Eight saved hot cues per track, auto-loops, loop roll and beat jump, all snapped to the beat grid.
Headphone cue
Preview the next track on a second output, like a USB headset, or split one output: mix left, cue right.
Record your set
Record to MP3 or WAV with a tracklist written next to it as text and a .cue sheet.
What next, with reasons
Pick a track and the What next panel lists library tracks that will mix well with it: compatible keys only, a tempo within reach, and energy similar or rising. Each comes with its reasons, like "same key (8A), +0.5 BPM, energy up 6 to 7". Tracks you've already played tonight are left out.
- Learns what you play after each track
- Works at the tempo the deck is actually playing
- Auto-mix can carry on with its best pick

Auto-mix and smart crates
Build a list and let auto-mix play it hands-free: each blend starts on the bar, beats synced, crossfader moving across and the bass swapped half-way. Smart crates fill themselves by tempo, key, energy, genre or words, and every track is analysed in the background for tempo, key and energy.
- Blend length of 8, 16, 32 or 64 beats
- Camelot key chips coloured round the wheel
- Reads Play by Zaweba's library

Mix FAQ
Can I use streaming music?
No. Streaming services license DJ use separately, so Mix only plays music files you own.
Do I need a DJ controller?
No. Everything works with a mouse and keyboard. If you have a MIDI controller, you can map it with learn mode.
Does it work with Play by Zaweba?
Yes. When Play is installed, Mix reads its library (without changing it), so your music is there straight away.
