GP Tone Builder
Tone Builder For Valeton
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Turn any song into a playable patch for your Valeton GP-5, GP-50, GP150 and GP-180.
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 processor.
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.
CHOOSE YOUR SIGNAL CHAIN
Build every patch around a full amp head and cabinet, or around SnapTone captures — switch between
Amp+Cab and SnapTone before you analyze, and the whole chain is built for the one you chose.
DOWNLOAD AND KEEP YOUR PATCHES
Save any patch as a preset file to your device. Load it later, keep a library of your favourites, or
transfer it however you like — the patch is yours once it's built.
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 the specific processor you own.
BLUETOOTH CONNECTIVITY
Pair your processor and send patches directly from the app. No cables, no file transfers, no manual
entry.
