Seven experimental sound engines. Each one turns a physical or mathematical simulation — chaos, phase transitions, quantum interference, morphogenesis — directly into audio. No oscillators, no samples: the model is the instrument. Plug in any MIDI controller and play the physics.
Every synth is a live simulation with its own physics, presets and scopes. What you see is literally what you hear — the visualization and the waveform come from the same state.
One click starts the Web Audio engine. Headphones recommended — several engines live near phase transitions where tiny parameter moves flip the whole texture.
Connect any MIDI controller (USB or Bluetooth) and it just works: notes set pitch, velocity sets level, knobs drive filters, FX and the physics itself. Or sculpt everything with the on-screen controls.
| Message | Every engine |
|---|---|
| Note on / off | Pitch — continuous (attractor dt, oscillator Hz) or rate-quantized on the scan engines (C2 → ÷32 … C7 → ÷1). On Reaction-Diffusion, notes also seed the field and gate the ADSR (held until all keys release). |
| Velocity | Output gain |
| Pitch bend | ±2 semitones (attractor, oscillator network) |
| CC 1 · mod | LFO depth (partials on the oscillator network) |
| CC 7 · volume | Output gain |
| CC 74 / 71 | Filter cutoff (log) / resonance |
| CC 91 / 94 | Reverb wet / delay wet |
| CC 20 / 21 | Two engine-specific physics params — ρ & morph, rule & write-strength, K & Δω, T & field, stiffness & tension, ε & θ, F & k |
All inputs, all channels (omni), hot-plug. USB controllers appear instantly; Bluetooth-LE MIDI devices appear once paired with your OS. Web MIDI needs Chrome or Edge — the status pill in each synth's corner shows connection state and blinks on activity.
