Two turntables and a battle mixer in one browser tab. Load a track on each deck, drag the vinyl to scratch, ride the pitch fader to match them, and cut between them on the crossfader. Hot cues, loops, rolls and a sampler sit under each deck, and your own audio files load straight from your computer.
One turntable from the set, with a beat behind it: grab the record and drag it back and forth. The speed of your hand sets the pitch, the direction sets which way the sound plays. DJ Master Pro gives you two of these and a mixer between them.
Each deck is its own player with a platter, a pitch fader and pads. Both meet in the mixer, where gain, EQ and the channel fader shape each side before the crossfader decides what you hear.
Two decks, a mixer built for cutting, and the pads that modern controllers added on top.
Start and stop with real motor torque, 33 or 45 RPM, a pitch fader with ±8% and a quartz button to snap it back to zero. Drag the vinyl to scratch, use the mouse wheel to nudge the pitch, and click the waveform to drop the needle anywhere in the track.
Gain, high, mid and low EQ, a VU meter, a channel fader and a CUE button that solos the channel, on each side. The crossfader has two curves: MIX for long blends, CUT for scratching, where the slightest move opens the channel.
Four modes on the same pads. Hot cues to jump to marked points, loops from an eighth of a beat to sixteen beats, rolls that loop for as long as you hold the pad and then carry on as if nothing happened, and a sampler for one-shots over the mix.
A sweepable filter for build-ups and drops, plus reverb and delay on the master. For more, the XY Matrix opens in another tab and plugs into the same GOONS mixer.
Browse crates of vocals, scratch sounds, drums and bass from the GOONS sample library, or import your own audio files. Imported tracks stay in your browser: nothing is uploaded.
Q and P start and stop each deck, the arrow keys move the crossfader and Space centres it. A MIDI DJ controller can drive the platters, and full screen mode gives the decks the whole display.
Each one uses a different part of the set: the platter, the crossfader, the pitch fader or the pads.
Two tracks at close tempos, MIX curve on the crossfader. Match the speed with the pitch fader, then bring the second track in over eight bars with the EQ low cut.
Load a scratch sample on deck B, a beat on deck A, and switch the crossfader to CUT. Baby scratches first, then chirps once the fader hand keeps up.
Set hot cues on the first beats of a phrase on both decks and trigger them in turn. It is beat juggling without needing two copies of the same record.
Hold a roll pad and shorten it from one beat to an eighth while the filter sweeps up. Let go on the drop and the track picks up where it would have been.
Pick from the crates or import your own files, then load one on deck A and one on deck B.
Press Q, open the channel fader and set the gain so the meter sits in the safe zone.
Start deck B with P, bring it in low on its channel fader and move its pitch fader until both beats stop drifting apart.
Use the MIX curve and the arrow keys for a smooth blend, or switch to CUT and start scratching.

A pair of turntables and a battle mixer is a serious investment before you know whether you like it. DJ Master Pro puts the same layout in a browser tab: two decks, a mixer with a crossfader built for cutting, and the pads that controllers made standard.
Scratch Master is a single turntable for learning scratch techniques over built-in beats. DJ Master Pro is the full set: two decks to mix between, a three-band EQ, hot cues, loops and rolls, and your own tracks. Start with one and move to the other when you need a second deck.
DJ Master Pro shares the GOONS mixer with the drum machines, samplers and effects of the studio. A new account opens it free for 7 days, like every app in the catalog - no card required. After that, it is part of GOONS PRO.
Yes. Import audio files from your computer and load them on either deck. They are read in the browser and never uploaded.
Yes. Click the vinyl and drag it: forward and backward motion sets the speed and direction of the sound, like a record under your hand. Switch the crossfader to CUT for chirps and transforms.
A MIDI DJ controller can drive the platters of both decks; you assign it from the deck and set the mapping in the GOONS MIDI settings. No controller is needed to play.
Hot cues are marked points you jump to with one pad. Loops repeat a length of the track, from an eighth of a beat to sixteen beats. A roll loops only while you hold the pad, then the track carries on from where it would have been.
Scratch Master is one turntable with practice beats, for learning to scratch. DJ Master Pro has two decks, a full mixer, pads and your own tracks, for mixing as well as scratching.
For your first 7 days, yes. A new GOONS Studio account opens DJ Master Pro, like every app in the catalog, with no card required. After that, DJ Master Pro is part of GOONS PRO at €9.90/month - your account and your projects stay.
