FX Builder 2.0: create from the mobile app

By Landon McCoy · Updated September 15, 2026

Create a custom effect in the Chaos Audio app, choose an optional finish, and install the result to your connected device.

Chaos Audio app preview · September 2026. This guide includes the mobile app’s optional pedal-finish workflow, which is not yet verified as available in every public app release. FX Builder 2.0 is available on the web at build.chaosaudio.com. If your mobile controls differ, use the update available through your app store and keep using your installed version’s controls.

Applies to: Stratus and Nimbus.

Create

  1. Sign into Chaos Audio and open FX Builder.
  2. Check Builds remaining, then enter a description of the core sound.
  3. Leave Pedal finish on Automatic or choose a finish. This changes the visual design, not the effect’s sound.
  4. Generate the effect and wait for the app’s success message.
  5. Find the effect in My Created FX and install it on the connected Stratus or Nimbus.
Create from the Chaos Audio app. Describe the effect: Check Builds remaining and enter your idea. Choose a finish: Automatic or an optional visual finish. Generate + install: Find the result in My Created FX. Chaos Audio app preview · A finish changes appearance, not the sound.

For more complex ideas

Start with the main sound and refine in stages. If the app suggests simplifying a complex request, use that as a way to isolate what you need rather than adding every feature at once.

If generation is interrupted

Check the result and your effect library before starting another generation. Keep the exact error if it fails. Account generation, downloading the effect, and installing it to hardware are separate steps.

After installation

Add the effect to a chain, adjust its controls, and save a preset. The same generated effect works across Stratus and Nimbus.
