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. SUPPORTED DEVICES - Valeton GP-5 - Valeton GP-50 - Valeton GP-150 - Valeton GP-180 SUBSCRIPTION Try free with 3 song analyses. Continue with $29.99/year for unlimited access.
