A stage of OSC-1. It works the same on its own page as it does in the chain — same parameters, same paths.
Noise
The layer that gives an attack its edge.
Audio and MIDI
Browser session
Audio is stopped.
Input · MIDI keyboard
Your keyboard is a keyboard. Middle row plays the white notes, top row the black ones. Z and X change octave. Keys are ignored while you are typing in a field.
Noise
A white, pink or brown noise source with a tone tilt. On its own it is wind and static; layered under an oscillator it is the breath in a flute and the click on a pluck.
Parameters
Noise
These knobs move the module's published schema, but the preview engine only renders OSC Mini, FX Mini and the OSC-1 chain — so they won't change what you hear yet.
Output · Audio signal
The signal leaving Noise, tapped after the output stage. It's a picture of what your speakers are getting.

Take it into your DAW.
Same DSP as this page. The plugin isn't a rebuild — it's the identical kernel from the identical TypeScript source, compiled native instead of to WASM.
Free forever, no account, and playing it in the browser will never ask you for one. VST3 and standalone today; AU and CLAP are on the roadmap.
Every knob, and what it actually does.
Generated from the module's parameter schema — the same source as the web UI, the worklet transport and the VST3 parameter table, so it cannot drift.
| Param | Range | Default | Units | What it does | Automatable |
|---|---|---|---|---|---|
| Noise | |||||
Typenoise.type | white · pink · brown | white | — | White is flat and hissy, pink falls 3 dB per octave and sounds natural, brown falls twice as fast and is nearly a rumble. | Yes (stepped) |
Levelnoise.level | 0 … 1 | 0.1 | — | Noise level into the voice mix. A little goes a long way - the default is deliberately low. | Yes |
Tonenoise.tone | -100 … 100 | 0 | — | Tilts the noise dark or bright without changing its type. Negative rolls off the top, positive rolls off the bottom. | Yes |
Parameter paths (filter.cutoff) are what you'll see in your DAW's automation list and in the SDK. Same names everywhere.
How it works.
A noise generator fills a buffer with the requested spectrum - flat for white, a one-pole cascade for pink, an integrator for brown - and loops it into the voice mix at Level, gated by the same amplitude envelope as the oscillators.
Tone is a one-knob tilt implemented as a shelving pair rather than a filter sweep, so extreme settings change colour without ever removing the noise entirely.
It's yours to read and to fork.
