w1n5t0n e3b94d644f feat(shapeseq): implement Layer 0 foundation modules 
Five independent modules with no interdependencies:

- event-bus.js: namespaced pub/sub (seq.*/ml.*/ui.*) with wildcard
  subscriptions and automatic AudioContext/performance.now timestamps
- prng.js: seedable mulberry32 PRNG with pure-functional API, fork()
  for independent per-primitive streams, serializable state for freeze
- pattern.js: symbolic pattern description data structure with
  create/clone/merge/validate, additive and multiplicative merge modes
- param-map.js: maps fixed 16-output MLP to variable-count primitive
  params via linear interpolation, with optional per-param min/max scaling
- seq-iml.js: factory for second WasmIML instance (2 inputs, 16 outputs,
  [16,16,16] hidden layers) following existing imlJoy/imlHand pattern

All modules are ES modules with no build step. PRNG, pattern, and
param-map are port-ready (explicit state, typed arrays, no closures).

NISPS Playground

Browser-based interactive demo of the NISPS ML engine.

Run locally

python3 -m http.server
# Open http://localhost:8000

Run the command from the playground/ directory.

What it does

  • Maps 2D joystick input (X/Y) through an MLP ([3, 32, 48, 64, 126]) to 126 outputs.
  • Visual mode: first 20 outputs drive a flow-field particle visualization on Canvas2D.
  • Synth mode (C15): all 126 outputs control the C15 WASM synthesizer — envelopes, oscillators, shapers, filters, feedback/output mixers, cabinet, and effects.
  • Supports two learning modes:
    • Examples: add explicit input/output pairs and train.
    • RL Feedback: give thumbs up/down while exploring outputs.

C15 synth parameters

The 126 synth parameters (js/synth/param-map.js) cover all sonically meaningful continuous parameters of the C15 engine. Excluded from the C15's 287 total params:

  • Hardware routing (56) — no physical MIDI in browser
  • Macro controls (12) — conflicts with direct ML control
  • Scale/tuning (13) — would break pitch
  • Key tracking / velocity (22) — depend on note context ML can't observe
  • Envelope mod depths (19) — too many multiplicative interactions for 2-input ML
  • Discrete/structural/dangerous (19) — pitch sweep, volume, switches, resets
  • Secondary config (15) — curves, chirp, shaper blend, source selects

UI controls

  • Output mode tabs (side panel): switch between Visual and Synth modes.
  • Expand / Collapse button on the canvas: makes the visual surface nearly full-screen and compresses lower controls into a minimal view.
  • Presets: quick demo mappings (Calm/Chaos, Rainbow, Vortex) — visual mode only.
  • Help (?) overlay: in-app usage guide.
  • Follow mode: double-click joystick in RL mode to toggle no-hold interaction.
  • Keyboard in Follow mode (RL): 2 = thumbs up, 1 = thumbs down.
  • Gamepad in RL: RB = thumbs up, LB = thumbs down.
