Two freeze modes for capturing and preserving musical state:
- Algorithm freeze: snapshot all primitive params + seeds. Individual
params can be selectively unfrozen for ML-driven exploration via
DeltaController (applies MLP deltas to frozen base values with
per-param boundary enforcement).
- Pattern freeze: snapshot the realized note pattern. The sequencer
bypasses the primitive chain entirely and loops the frozen pattern.
Extracts _runPipeline() from setSequenceInputs() for reuse.
The dirty-check that skips re-evaluation when inputs haven't changed now
also checks a generation counter. Config changes (tempo, step count,
projection, chain edits) bump the counter, ensuring the pipeline re-runs
even when joystick position is static.
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.
Replace the composable transform chain (VelocityCurve, GateThreshold,
RangeMap, OctaveFolder, StutterMap, presets) with 3 straightforward
post-chain knobs: velocityCurve, gateThreshold, and pitchRange. The
old system was over-engineered for a research prototype — the new API
is easier to wire to UI controls and reason about.
PitchWalker was classified as a generator but always consumed the
incoming pattern's triggers. Reclassify as a processor so it modifies
the pattern produced by an upstream generator (clonePattern instead of
createPattern). Add reEvalOnLoop flag on the Primitive base class; when
set, the sequencer re-evaluates the chain at each loop start so
stateful primitives produce evolving patterns across loops.
Generators can now have independent step counts. When merging patterns
of different lengths, both are tiled to their LCM. Chain exposes
setGeneratorStepCount/getGeneratorStepCount for polyrhythmic control.
Replace the pitch*127 encoding hack with a dedicated midiNote field on
pattern steps. IntervalLock now writes integer MIDI notes to step.midiNote
while preserving the original [0,1] pitch for other consumers. The clock
and sequencer bridge pass midiNote through the event pipeline.
Also reworks mergePatterns to be trigger-aware: when only one generator
fires at a step, use its values directly instead of averaging with the
other generator's defaults.
