## What is GP Tone Builder?

Turn any song into a playable patch for your Valeton GP-50 or GP-5.

GP Tone Builder uses AI to analyze the guitar AND bass tone of any song and map it directly to the effects and
parameters on your Valeton multi-effects processor. Search for a song, pick guitar or bass, and the app does the rest
— from audio separation to tone analysis to sending the patch straight to your device over Bluetooth.

HOW IT WORKS

1. Enter a song name and select Guitar or Bass.
2. The app downloads the audio and isolates the guitar or bass track using AI-powered stem separation.
3. Advanced audio analysis extracts spectral features, detects the key, and identifies distinct tone sections — clean
intros, overdriven verses, distorted choruses, and more.
4. AI maps the analyzed tone to the exact effects, amp models, and parameter values available on your Valeton GP-50 or
GP-5.
5. Send the patch to your device instantly via Bluetooth Low Energy.

DETAILED TONE ANALYSIS

Every song is broken down into multiple tone sections, so you get a patch for each part of the song, not just a single
average.


BUILT FOR YOUR VALETON HARDWARE

GP Tone Builder uses the same effects, amp models, and parameter ranges as the official Valeton firmware. Every patch
is built from the ground up for GP-50 and GP-5 hardware.

BLUETOOTH CONNECTIVITY

Pair your GP-50 or GP-5 and send patches directly from the app. No cables, no file transfers, no manual entry.
