Turn a sound idea into an effect. Describe: Name the sound and controls you need. Listen + refine: Compare, then ask for one specific change. Publish + install: Save to your account; transfer with the app. Once installed, the finished effect runs locally on Stratus or Nimbus.

Start with a clear prompt

Describe the core sound, what you will play through it, and the controls you need. For example: “A warm delay for clean guitar, with controls for time, repeats, tone, and mix.” Start simple; add one change at a time after listening.

From an idea to hardware

  1. Sign into your Chaos Audio account and check your build balance.
  2. Describe the effect and generate it. Keep the generation open until it reports a result.
  3. Listen and adjust the controls. Refine the prompt if the behavior needs to change.
  4. Publish to your account, then use the mobile app to install it to the hardware.

What uses the cloud?

Generation and compilation require internet access. Once installed, the finished effect runs locally on Stratus or Nimbus. A web preview is useful for auditioning, but it is not a recording of your physical hardware.

FX Builder 2.0 preview

The upcoming web workflow uses Studio → Design → Share; the mobile app adds an optional pedal-finish picker. See the dedicated preview guides in this category.
