ABOUT TONE LAB AI

AI guitar tones for your BOSS Katana.

Tone Lab AI helps you shape your guitar sound with plain-language requests and browser controls. Read your USB-connected Katana, adjust its amp and built-in effects, and review every proposed change before applying it.

How to create a Katana tone

  1. Connect your amp. Open Tone Lab in desktop Chrome or Edge, install the matching BOSS USB driver if your model needs one, and connect with a USB data cable. Close BOSS Tone Studio, choose your amplifier model, and allow MIDI and SysEx when you click Connect amp.
  2. Describe your sound. For AI suggestions, choose OpenAI or Claude, paste your own API key and select an available model. Ask for a warm blues lead, a tight rock rhythm, or a small adjustment such as less treble. You can also enter your guitar type or stage manual changes without an API key.
  3. Preview, then play. Inspect the proposed amp, EQ, and effect settings. Choose Apply tone when you are ready. Tone Lab reads the amp back to verify the requested values and keeps restoration history in your browser.

Apply changes your current tone. Choose Write to device to save it in a model-specific amplifier preset after reviewing the overwrite.

Before you plug in

Do I need an API key?

AI tone suggestions use your own OpenAI API key and API billing, or an Anthropic API key and API billing for Claude. Manual controls, amplifier reads, and restoration do not need a key. Your browser sends AI requests directly to the selected provider. Keys stay in page memory unless you explicitly choose to remember a separate key for each provider in this browser.

Which browsers work with Tone Lab AI?

Use desktop Chrome or Edge with Web MIDI and SysEx permission, and open the hosted app over HTTPS. Safari and browsers on iPhone or iPad do not provide the required Web MIDI access. GO:2 use with Android Chrome still needs hardware testing.

Can I ask for an artist or song tone?

Yes. Describe the artist, song, or sound you want, and optionally include your guitar and pickup type. Tone Lab uses a built-in gear library and can research artist or song gear with compatible OpenAI or Claude models. Suggested Katana settings are starting points to review and adjust by ear.

Can I undo a tone change?

Recent changes keeps local restoration records for mapped controls. Preview a restore, then apply it to return those controls to their previous values. This history is stored in your browser and is not a complete amplifier patch backup.

Is Tone Lab AI an official BOSS app?

Tone Lab AI is an independent project and is not affiliated with or endorsed by BOSS or Roland. Use the matching BOSS Tone Studio application for full editing and portable Librarian backups.
