// The Engine

SOUND, SYNTHESIZED FROM TEXT.

A diffusion model trained on the texture of music itself — not a library of loops. Every output is original signal, generated on demand and owned by you.

01

Prompt → Full Track

Type "dark acid techno with a broken 808 and detuned arps." The model returns a complete, mixed, loopable track in seconds. Steer it with mood, BPM, key, and reference vibes.

02

Stem Surgery

Split any generation — or any track you upload — into clean drums, bass, melody, and FX stems. Mute, swap, regenerate a single layer without touching the rest.

03

Texture Lab

Generate foley, drones, risers, and impossible sound design that no field recorder could capture.

04

Voice Steering

Talk to the engine mid-render. "More tension. Drop the kick. Make it feel like 3am." It adapts live.

05

Own Every Output

100% royalty-free and clearance-free. Ship it in a game, film, or release — no strings, no PROs.

// Workflow

THREE MOVES TO SIGNAL.

From empty timeline to finished sound design without leaving the browser.

01

Describe the noise

Prompt in plain language or hum a melody. Set BPM, key, and intensity, or just let the model run wild.

02

Shape & regenerate

Lock the parts you love, reroll the rest. Split to stems, nudge the energy, and dial the mix in real time.

03

Export & ship

Bounce to WAV stems or a mastered mix at 48kHz. Drop it straight into your DAW, game, or release.

Can You Run AI Music Generation Locally for a Live DJ Set? Magenta, Stable Audio, and an FLX4 on the Desk

You turn the filter knob on the FLX4, and there's a beat — not a musical one, a dead one — before the audio answers. Three hundred milliseconds, maybe four hundred. In a studio that's nothing.

Where AI Music Generation Gets Its Sound: A Short History of a Borrowed Library

A figure-skating routine goes viral. The music underneath sounds like a song you half-remember — the hook lands where you expect, the vocal grain is familiar, the chord turn at the bridge is the one…
