Make a tune

Everything renders here in your browser. Nothing uploads. A favorite is just its seed, so it re-renders identically forever.

Feel

Press Randomize to roll a track in this style, or Random style to jump somewhere new.

sec

Same seed, same track — every time, on any device.

bpm

Blank lets the seed choose.

Crossfades the end into the start and rounds to whole bars, so it repeats cleanly.

Opens a gap where a voice sits, and lands every bed on the same loudness.

Whoever opens your link hears it straight away, or on their first click.

Off by default, so the studio opens and renders straight away. Tick it to swap the synthesized drums and strings for recordings — a real kit, percussion, pizzicato and bow attacks. The first render then fetches 3 MB for most styles, 8 MB for Score, once per browser. Same seed either way.

Shape Nine sliders. Center is the preset exactly as shipped.
Press ▶ on any slider to hear its two extremes back to back.
Sections & delivery Section lengths and loudness, straight off the readout. Auto is hands-off.
Section lengths apply to the next render; loudness and peak are instant.
