AI-powered guitar preset generator for Line 6 Helix and HX devices.
You spent $700 on the pedal. You shouldn't have to spend 3 hours dialing in a tone.
Tone Architect listens to what you want — an artist, a song, a vibe — and generates a complete, ready-to-import preset file for your Line 6 device. Every block, every parameter, every signal chain order. Done in seconds.
No subscriptions. No cloud. No API keys. Just your Mac, your pedal, and the tone you've been chasing.
brew install --cask memogonzalezj-dev/tap/tone-architectRequires Apple Silicon (M1 or later) and macOS Monterey or later.
Type something like:
"Edge of U2, Sunday Bloody Sunday, with a Fender Strat"
And Tone Architect:
- Selects the right amp model, cab, drive, and effects from your device's exact block library
- Orders them correctly in the DSP signal chain
- Sets every parameter to a musically sensible value
- Generates a preset file you can drag directly into HX Edit
The AI runs entirely on your Mac using Apple Silicon — no internet required after the one-time model download.
- Natural language input — describe any artist, song, or tone in plain English
- Multi-device support — Helix Floor, Helix LT, HX Stomp XL, HX Stomp
- 200+ verified block IDs — every model ID confirmed from real device exports, no guessing
- Clean output — imports into HX Edit without errors or "unrecognized model" warnings
- Correct signal chain ordering — dynamics → wah → pitch → drive → amp → cab → EQ → mod → delay → reverb
- Parameter guardrails — all values clamped to valid ranges, no silent or blown-out presets
- 100% offline after setup — your tone stays on your machine

Tone Architect runs Meta Llama 3.1 8B locally via node-llama-cpp, accelerated by Apple Metal. The model is guided by a system prompt that constrains output to valid Line 6 internal block IDs, correct parameter ranges, and proper signal chain structure.
The generated JSON is built into a fully compliant .hlx file — including device ID, snapshot configuration, DSP routing, and all required metadata — that HX Edit accepts without modification.
Nothing ever leaves your Mac.
