fix(mq_editor): offset playhead to partial t_start when playing single partial (key 3)

2026-02-19T06:47:17Z

handoff(Claude): playhead offset fix for single partial playback

fix(mq_editor): remove duplicate mode toggle, add SINE badge, fix mini-spectrum invalidation

2026-02-19T06:26:26Z

- Remove redundant synthModeToggle from _updatePropPanel + index.html - Add SINE badge (grey) to panel title, matching existing RES badge (blue) - Invalidate mini-spectrum (viewer.render) on sinusoid/resonator switch handoff(Claude): mq_editor partial panel polish

feat(mq_editor): UI revamp — params panel, layout, partial spectrum

2026-02-19T05:46:57Z

- Move Synthesis controls (integratePhase, jitter, spread, resonator, LP/HP filters) and Auto Spread All into the ⚙ Params dropdown - Group Extract Partials / +Partial / ✕ Clear All in one toolbar group - Add per-partial Sine/Res mode toggle in the property panel (Mode row) - Move partial mini-spectrum below the right panel (right-col layout) - Partial mini-spectrum: dynamic dB range scanned across full duration (8 samples, [peak−60, peak]), cached on partial select - Print bezier amplitude A= in red at top-right of partial spectrum - Status/info messages set to 80% gray (#ccc) handoff(Claude): UI revamp complete, TODO items implemented.

fix(mq_editor): jitter + central spectrum invalidation

2026-02-18T23:32:54Z

mq_synth.js: - jitter was only used as a static initial phase offset (inaudible); now drives per-sample LCG frequency perturbation (±jitter fraction of instantaneous freq) in both sinusoidal (integratePhase path) and resonator modes (separate jitterSeed, independent from noise excitation) - disableJitter option now correctly gates jitter to 0 in both modes (was never read before) viewer.js / app.js: - remove invalidatePartialSpectrum() and onResonatorParamChange callback; replace with viewer.onGetSynthOpts callback, called inside _computePartialSpectrum to pull fresh synthOpts at compute time - all UI changes (resonator r/gain, forceResonator, globalR/gain, forceRGain, sinusoidal params) now use viewer.render() as the single invalidation path — no more split between render() and invalidatePartialSpectrum() handoff(Gemini): jitter active on both synth modes; spectrum always sees fresh synthOpts via onGetSynthOpts; viewer.render() is the only invalidation path needed.

fix(mq_editor): fuse spread_above/below into single spread param

2026-02-18T23:00:06Z

Asymmetric spread offset the pitch center. Replace with a single symmetric `spread` in harmonics config. autodetectSpread now returns max(above, below). Update all defaults, UI, comments, and README. handoff(Gemini): spread is now a single param; no compat shims. Co-Authored-By: Claude Sonnet 4.6

fix(mq_editor): partial mini-spectrum — correct FFT, time selection, resonator sync

2026-02-18T22:55:02Z

- Fix: fftRadix2 called without bitReversePermute → noisy spectrum (use fftForward) - specTime = mouse pos if inside partial [t0,t3], else center of partial interval - Cache check moved before canvas clear to keep spectrum visible outside [t0,t3] - viewer.synthOpts forwarded to synthesizeMQ so forceResonator/globalR/gain apply - invalidatePartialSpectrum() wired to forceResonator/forceRGain/globalR/globalGain handoff(Gemini): mini-spectrum now correct; fft bug fixed, resonator mode synced

feat(mq_editor): partial spectrum viewer — synth+FFT power display

2026-02-18T22:25:46Z

Adds a 200×100 canvas (left of the main spectrum overlay) that shows the synthesised power spectrum of the selected partial at the time under the mouse (or playhead). Pipeline: synthesizeMQ → Hann window → FFT (2048-pt) → dB power bars. - freqCurve times are shifted so the synthesis window is centred on t - X-axis: log-frequency (same scale as main view) - Y-axis: dB, normalised to peak of the synthesised frame - Cache: {partialIndex, time} → avoids re-synthesis on mouse move; bypassed (force=true) from render() so param changes always redraw handoff(Claude): partial spectrum viewer complete Co-Authored-By: Claude Sonnet 4.6

feat(mq_editor): replace replicas with harmonics model

2026-02-18T21:59:15Z

- Fundamental f0 always synthesized; harmonics added at n*freq_mult - decay^n amplitude rolloff per harmonic (capped at 0.90) - Resonator mode also expanded across harmonics (per-harmonic y1/y2 state) - UI: h.decay, h.freq (default 2.0), jitter, spread↑/↓ params - Viewer: faint dotted harmonic bands with spread visualization - Default freq_mult=2.0 (natural harmonic series) handoff(Gemini): harmonics model complete, ready for next task Co-Authored-By: Claude Sonnet 4.6

fix(mq_editor): swap keys 1/2 — 1=original, 2=synth, 3=partial

2026-02-18T20:50:54Z

handoff(Gemini): key bindings updated in app.js and README.md
