Low Latency DSP

Pedal chains run in one process and share a JACK client for fast response while you play.

Keyboard + MIDI

Dial knobs, bypass pedals, cycle presets, and navigate profiles directly from the terminal.

YAML Chains

Profiles and presets are plain YAML—easy to version, remix, and keep in your own repos.

AI Workflow

Build Chains with LLMs

Ninevolt profiles are plain YAML, so assistants can draft song-inspired chains quickly. Use the authoring guide for valid files and cited tone research.
