Chorus
These knobs move the module's published schema, but the preview engine only renders a few modules so far — OSC Mini, FX Mini, Amp Rig, Space Mini and the OSC-1 chain — so they won't change what you hear yet.
Keyboard
Chorus
Play the module directly — nothing to cue.
Chorus
One voice, pretending to be several.
A stage of OSC-1. It works the same on its own page as it does in the chain — same parameters, same paths.
About
A modulated short delay against the dry signal. The detune-and-blur effect that makes a thin patch sound wide without adding a single note.
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.
How it works.
A short delay line whose delay time is swept by an LFO at Rate, summed with the dry signal. The sweep Dopplers the delayed copy slightly sharp and flat, and the interference between the two copies is the whole effect.
Because it is interference, the mix control is not a level control: at full wet you lose the comb filtering that makes it sound like chorus and are left with plain vibrato.
It's yours to read and to fork.

npm run devThe codex CLI name is proposed, not shipped. That command gives you this module's DSP, schema, presets and UI as a local project — change a number, hear it immediately.
