The sequence MLP output count is now configurable (default 16). Hidden
layer widths scale with the output count to keep inference cheap while
providing sufficient capacity. The sequencer exposes setOutputCount()
to resize the MLP at runtime.
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).
