Beta 1.0.0-beta1, updated 26 October 2026 · Windows 10 & 11, 64-bit · Code-signed installer

RIDDIM DECK with its Pioneer DDJ-SR2 layout: two decks, the mixer between them, effects and performance pads — The DDJ-SR2 layout - the screen mirrors the controller in your hands.

Everything on one screen

Two or four decks

Sync, key lock, pitch, eight hot cues per deck, loops, loop roll, slicer and slip - with beat grids you can nudge and keep, per track.

Stems, on your machine

Split any track into vocals, drums, bass and the rest - processed locally, no upload, no subscription to a cloud service.

A censor that listens

Word detection finds the lyrics that need cutting, so you can clean a track before the radio edit exists. Reverse or mute, right on the deck.

Route anything anywhere

Master, headphones, booth and record outputs, each to whichever device and channels you choose - even a second sound card, kept in time.

Mic on the mixer

Gain, EQ and talkover ducking, plus a voice strip with filter, flanger, delay and reverb for toasting over the riddim.

Go live

Stream to YouTube or any RTMP service, run your own Icecast station, or serve the mix over HTTP - and record the whole set while you play.

Bring your library

Import crates and cue points from Serato, rekordbox and VirtualDJ. Smart crates, BPM and musical key (Camelot too), analysed and cached.

Take it to the club

Export to a USB stick that CDJs can read - beat grids, cues and waveforms included.

Hands on

Controller layouts that match the hardware, MIDI learn for everything else, an eight-pad sampler and digital vinyl control. On the DDJ-SR2: all four decks, needle search, and stems and loops from the pads.
