FX Builder 2.0: create from the mobile app

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 connect your hardware. Open FX Builder using the stars button on Pedalboard or Add Effect → Create My Own, as shown in the tutorial.
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. On the successful result, choose Add to Pedalboard when offered. This downloads and installs the account effect to the connected hardware. You can also find it later in My Created FX.

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

Tap the generated effect’s virtual footswitch to enable it, adjust its parameters, and compare the result at a comfortable listening level. Save the chain as a preset. Sync that preset to hardware if you want to recall it without the phone. Creating or privately publishing an effect does not automatically submit it to the public Tone Shop.

The tutorial demonstrates this workflow in the updated app. If your installed app does not offer these controls, use the released web builder or your app’s available workflow; the mobile finish picker remains subject to the preview notice above.
