The first synthesizer with AI oscillators. Describe a sound in words and play it. Powered by a real neural audio model running locally on your machine.
Triple Helix runs a real neural audio model — ACE-Step 1.5 — locally on your machine. No cloud. No subscription. Describe a sound in plain English, and the model generates it. Then play it like any synthesizer, with full MIDI control, modulation, and effects.
Can't run the 3.5 GB model? Triple Helix falls back to a Claude API path or a built-in rule-based generator. It always makes a sound.
An AI oscillator powered by ACE-Step 1.5 — a real text-to-audio diffusion transformer running via GGML. Type "warm analog pad" and get exactly that. 3.5 GB of models bundle with the plugin.
A spectral-domain oscillator with full harmonic control. Draw, morph, and automate individual partials. Bridges the gap between additive and AI generation.
A complete wavetable oscillator with position scanning, wave morphing, and spectral interpolation. Use factory wavetables or import your own.
Three oscillators (neural, spectral, wavetable) route through three filters into a full effects suite. A mod matrix, macros, and an arpeggiator tie it together. 30,000+ lines of DSP.
ACE-Step (local, offline, 3.5 GB) → Claude API (cloud, optional) → Rule-based (instant, always works). Triple Helix never fails to produce a sound, regardless of your hardware.
Every DSP primitive — wavetable interpolation, spectral morphing, neural inference glue — is unit-tested with Catch2. This isn't a toy. It's 30,000+ lines of production C++.
