A full turntable in a browser tab. Grab the platter with the mouse and it responds like vinyl - push it forward and the pitch rises, pull it back and the sample plays in reverse. Eight classic scratch sounds, four beats to practise over, and a cut button where the crossfader would be.
The vinyl is not a picture that spins. Its rotation drives playback rate directly, so the speed and direction of your hand become the speed and direction of the sample - which is the only way scratching ever feels right.
No skeuomorphic dust and crackle for its own sake - just the controls you actually put your hands on.
Click the vinyl and move it. Forward motion speeds the sample up, backward motion plays it in reverse, and letting go returns it to the platter speed. That single behaviour is what makes baby scratches, tears and drags possible instead of just simulated.
Scratch, Ahh, Yeah, What, Fresh, Horn, Vocal and Bass - the vocabulary most scratch routines are built from. Load one onto the platter and it becomes the thing you are cutting.
Boom bap for the classics, trap for modern tempos, lo-fi for slower practice and old school for the straight-ahead pattern everyone learns on. The beat runs in time and the BPM sits on screen so you always know where the one is.
Switch between 33 and 45, then trim with the pitch fader - the readout shows the exact percentage and the strobe lamp reacts the way a platter dot does. It is the same feedback loop you would use to beat-match on hardware.
A crossfader cut sits under your other hand. Chop it against a platter movement and you get transforms, stabs and chirps - the difference between dragging a sample and actually cutting it.
Waveform display, rotation readout, signal LED, beat LED and the strobe lamp. When a scratch does not land, the picture usually tells you whether you were early, late, or never on the sound at all.
Each one is a combination of platter motion and cut timing - start slow, over the boom bap beat.
Push the platter forward and pull it straight back, cut open the whole time. No fader work at all - just clean, even motion. Everything else is built on this.
Start closed, open the cut as you push forward, close it as you pull back. The sample gets a hard attack and a clipped tail - that is the chirp.
Hold a steady forward drag and chop the cut button in a pattern. The platter does nothing clever; the rhythm is entirely in the fader hand.
Move the platter far slower than the record speed, cut open. The sample stretches into a low growl - perfect over lo-fi, and the easiest way to hear how rate follows your hand.
Hit start and the vinyl spins. Pick 33 for the classic feel or 45 if you want everything brighter and faster.
Choose one of the eight scratch samples. Start with the plain "scratch" sample - it is the one designed to be cut, so you hear your hand rather than the recording.
Boom bap at a comfortable tempo. Practising in silence teaches you motion; practising over a beat teaches you timing, and timing is the harder half.
Once forward-and-back is even, bring in the cut button. Chirps and transforms are just baby scratches with the fader doing something - which is why the order matters.

The barrier to scratching has never been talent, it has been a deck, a mixer, a needle and somewhere to put them. Scratch Master removes all four. The platter responds to the speed and direction of your hand the way vinyl does, the cut button sits where a crossfader would, and the whole thing opens in a tab on whatever machine is in front of you.
Four beat styles give you something to be in time with, and the waveform, the rotation readout and the strobe lamp show you what actually happened. Most early scratching goes wrong in one of two places - the motion is uneven, or the cut is a beat late - and both of those are visible here before you have finished arguing with yourself about which it was.
Scratch Master shares the GOONS transport and audio graph with the drum machines, samplers and effects, so a routine you practise here has somewhere to go. One subscription covers every app in the catalog, and a 7-day free trial covers the deciding.
Yes, and better than you would expect, because the platter maps your movement to playback rate and direction rather than triggering a canned effect. It will not replace muscle memory built on real vinyl, but the timing, the motion and the fader coordination all transfer.
Eight: Scratch, Ahh, Yeah, What, Fresh, Horn, Vocal and Bass. They cover the standard vocabulary of classic routines, and the plain "scratch" sample is the one to learn on because you hear your hand rather than the source recording.
Four styles - boom bap, trap, lo-fi and old school - with a stop control and a live BPM display. Practising over a beat is what teaches timing; the beat LED gives you the downbeat when your ears are still learning it.
It acts as a crossfader cut. Combined with platter movement it produces the standard fader techniques - chirps, transforms and stabs. Baby scratches need no fader at all, which is why they are the first thing to learn.
Switch between 33 and 45 RPM, then trim with the pitch fader, which shows the exact percentage and drives the strobe lamp. It behaves like the pitch control on a hardware deck, so beat-matching practice works the same way.
