Play it
Drag the big dials — intensity and spread lead — and set the tempo and key. It responds as you move, and there is more when you want it: change rate, layers, flow, level, and a routing matrix you can edit.
The generative, deterministic multifractal musical instrument
No AI. Just math mixed with your creative touch.
What you can do
Keep it
Capture a loop when it sounds good, stack a few, and export them as MIDI or audio in your own key and tempo. What you make is yours.
Own it
The full instrument is free in your browser — every shipped pack included. A one-time unlock adds export and exact-take sharing: paid once, owned forever, no subscription.
Share it
Send a link and someone opens the same setup, live, on any device — one move from making their own.

The Studio — the room around the instrument
The player conducts; the Studio layers and mixes. Stack the takes you capture, balance and place each one — EQ, pan, space — and re-voice any genre with an instrument made from one of your own recordings. The whole Studio is free in your browser on a computer, with three named sketches to keep; exporting stems and MIDI and saving WAV takes are part of the same $59 one-time unlock as the player.
Play Fenophone in your DAW
Fenophone runs inside your DAW as a VST3/AUv3 instrument — the same engine as the browser. It locks to your project's tempo, automates from the host, switches genres on the bar, and saves its state with your project. Own it once: $99, or $129 bundled with the web unlock.
Embed Fenophone in your game
The engine embeds in games as an adaptive-music runtime — Unity, Godot, Unreal, or any C/C++ engine. Gameplay drives the music live, mood changes land on the next bar, and replays stay in sync because the same seed plays the same score. Free for jams; a one-time per-title license to ship.
