- Packet 1: durable schema (filter/filterEnv/LFOs/typed mod-matrix/ pitchBendRange) + clip.automation on all clip variants; widen IMidiSynth.scheduleNote with a note-local automation window; slice helper; history snapshot/restore + full save/load round-trip. - Packet 2: subtractive DSP (osc -> BiquadFilter -> amp, carrier-node additive matrix, linear filter env, keytrack, per-voice LFOs, live voice stealing + offline analytic voice cap). New simple-synth tracks default to a subtractive patch; legacy saved instruments stay bare. - Packet 3: layout-agnostic synth panel sections (Oscillator/Filter/ Envelope/Lfo/ModMatrix) + SVG CC breakpoint-envelope lanes with a lane selector in the piano-roll controller area (edits clip.automation). - Packet 4: 8-patch built-in preset bank + user save/load (settingsStore) + preset picker that reflects the loaded patch's name. Phase-1 complete; deferred follow-ups (motorized faders, absolute-cutoff automation, cut/merge automation) tracked in the plan doc §13. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…§14) General, instrument-agnostic channel so any instrument's UI shows the live automated value of a parameter during playback. Re-derives value from base patch + clip automation (never reads the DSP) — deterministic, offline-parity, survives the future WASM DSP swap. - instrumentParams/: param descriptors + registry + pure evaluateParamAt - liveParamBus + activeMidiClip + useLiveInstrumentParams rAF driver - SynthSlider paramId -> imperative ghost thumb/fill/badge (no re-render) - wired cutoff, gain, pitch-LFO depth; shared CC-range consts in synthVoiceMath Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…ollers - SynthSlider gains a `scale` prop (linear/log/power); native range runs on normalized position and maps through the taper. Motorized ghost uses the same map so fader and ghost stay in lockstep. - log: cutoff, LFO rate (equal travel per octave). power: gain, env A/D/R, filter LFO depth (fine low-end, reaches 0). Others stay linear. - Piano-roll controller-area toggle relabeled Velocity -> Controllers (it now hosts velocity + the four CC lanes).

- common/Knob: general rotary knob (taper + drag-to-turn + right-click reset + a11y). No MIDI dependency; a generic subscribeLive escape hatch drives the imperative automation overlay, so any live source can animate it. - SynthKnob: thin wrapper binding paramId -> liveParamBus (mirrors SynthSlider). - FilterSection rebuilt as a compact knob row (Cutoff/Res/Env Amt/Key Trk); Cutoff shows its live automated value. Saves vertical space. - Move sliderScale to common/ (slider + knob share it). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- EnvelopeGraph: classic ADSR shape drawn under each envelope, redraws live on edit; capped width + centered. - Oscillator (Gain, Bend Rng) and both ADSR envelopes now use knobs. - Oscillator|Amp Envelope and Filter|Filter Envelope sit side by side. - Knob: pointer-capture instead of pointer-lock (no cursor hide / panel scroll). - Update OscillatorSection smoke test for the knob (keyboard nudge). Docs: motorized-fader §14.6; new open-bug doc + ongoing index entry for the pre-existing timeline section-split jitter (not fixed here).

- Fix: history serialization guard flagged ANY key named `source` as a runtime
handle, so a mod-matrix route's string `source` ('velocity', …) aborted project
load ("not serializable plain data"). Only guard runtime-payload keys when the
value is actually an object handle; plain primitives pass. Real handles are
always objects, so media-clip protection is unchanged.
- LFO Rate/Depth and Mod Matrix Amount are now knobs; LFOs lay out two-up.
- Instrument+Preset share a row; Oscillator|Filter over Amp|Filter envelopes;
LFO(2/3)|Mod Matrix(1/3); narrower LFO label column.

- EnvelopeGraph is now editable: drag the attack/decay/release/sustain breakpoints. Each of A/D/R maps its REAL value into its own fixed-width slot (independent — turning Decay never moves the attack curve); release is anchored to the right edge and measured backwards; sustain is the flexible plateau at its (linear) level. Absolute cursor tracking; edits flow through the same onChange as the knobs, so graph + knobs + audio stay in sync. - Graph-only power taper (γ3) tuned so short A/D/R still render with visible width and presets fill their slots. - Governance baselines: register the motorized-fader rAF hook in the getState policy (+1) and acknowledge #298 type-barrel imports (557->559); trim the policy file back under its 300-line registry budget. - Docs: plan §14.6 updated for the knob UI + interactive envelope.

Resolve conflict in loadStateGeneratedClipRestore.ts: keep staging's helper extraction/light-clip support plus this branch's `automation` field on restored generated clips. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
MIDI (note bars) and audio (waveform) clips already canvas-draw their own body preview, so the FileTypeIcon pictogram overlay (piano/speaker) was redundant clutter sitting on top of the previsualization and hurting legibility. Gate `showIcon` off for any clip type with a body preview. Record the rule as an explicit invariant — "never perturb the clip previsualization" — in both the overlay code and docs/Features/Timeline.md, and update the pictogram test.
