the stems loop stage: four decks of three-band waveforms, the deck panels, the live mixer, and loop-0 writing the next stretch

how a set goes

your records, then where they go next.

play a record like always. press fork and loop-0 listens to the whole mix — every deck, as you’ve blended it — and writes what comes after, in key and on the grid. when you want it, it’s there on deck 2. bring it in, play another record, fork again.

01

fork

loop-0 hears the room — both decks, the eq, the fx — and continues that, from the next bar. press it again any time for a fresh take.

02

drop

when it’s ready, it waits. drop starts it on deck 2 at exactly where your mix has got to, on the beat. bringing it in is yours.

03

chain

before a take runs out, loop-0 writes the next stretch from the last bar the room heard. it never has to stop.

04

flow

switch it on and the set runs itself: your record, loop-0’s take, the next best record, its take. it backs off the moment your hands are on.

plug in

it knows your setup.

in the booth, your cdj-3000x players are the decks and the djm mixes: each player plays its deck out of its own outputs, loop-0 included, like any record. at home, plug in a ddj-flx10 or ddj-flx4 and the screen becomes that unit: its decks, its mixer, its pads lit, its sound card as the output. on the flx10 the jog screens show bpm, key and time — no more “no audio driver”.

on your mac

it all runs on the laptop.

loop-0 is the stems model. it comes down once, with your free stems key, and from then on nothing leaves your mac — no account needed to play, no connection needed at the gig.
