A drum machine that runs in this page. Four synthesised voices — kick, snare, hat, clap — a sixteen step sequencer, and a WAV export you can drop straight into your DAW. Nothing to install, nothing to sign up for, no samples to download. Every sound is built from oscillators and noise on the spot, which is why the whole thing weighs less than a photograph.
The kick is the reason it exists. It is a three layer EDM kick: a click for the attack, a pitched punch for the body, and a sub that carries the weight — the same build I use for my own releases as FDR-Sound.
How to use it
- Punch a step — click a slot in the grid. Click it again for an accent, which plays that hit louder. A third click clears it.
- Play — the Play button, or the spacebar.
- Hear one voice on its own — click the voice name in the grid to trigger it, or press 1 to 4.
- Shape a sound — drag a knob up or down. Hold shift while dragging for fine control, double-click to reset it. The reading under each knob shows the exact value.
- Start from a pattern — the presets load a rhythm and retune the kick to match the style.
- Push it off the grid — swing delays every second step. Around 20% loosens a straight beat without making it sound broken.
- Share what you made — Copy link puts the entire state, pattern and knobs, into the address. Send it to someone and they open your patch.
- Take it with you — Export WAV renders one, two or four bars as a 44.1 kHz file.
Getting a kick that sits in your track
- Tune sets the note the kick lands on. The readout shows it, so you can match it to the key of your track — a kick in the wrong key fights the bass.
- Pitch start and Drop decide the character. Higher and shorter reads as harder; lower and longer reads as deeper.
- Sub decay should stay shorter than the gap between kicks. At high tempo a long sub blurs into the next hit.
- Drive adds loudness and grit, but it eats the transient. If the kick disappears on small speakers, turn drive down and Click up.
Good to know
Works in Chrome, Firefox, Edge and Safari, on desktop and phone. On iPhone you have to tap once before any sound plays — that is Apple’s rule, not a bug. Nothing you do here is uploaded or stored: the tool runs entirely in your browser, and your pattern lives in the link, not on a server.
Loops you export are yours. Use them in your own tracks, releases and sets, no credit needed.
