Re-derives the splice-cadence inequality and adds a corner probe that FAILS at
P=500 by design, pending a ruling. Names the baseline commit and harness edit,
fixes measurement methodology, corrects the Trigger-AHD/rate coupling framing.
Generalizes the correlation-aligned SOLA delay line so the feed and the shift are
independent rates over one ring. Unity is bit-identical to the shipped read, asserted
against a hash baseline captured pre-change.
Guards params_payload.cpp's filter-tail seconds and both keyTrack sites against NaN; pins Voice::start's Trigger-span formula against trigger_seam; retires unused shortestDivisionAtLeast.
Payload v12 appends the new velocity->pitch curve and folds the retired filter velAmount into its now-bipolar curve, so pre-v12 projects reopen sounding identical. Preview button takes a drawn play triangle.
Normalizes crossfadeWeight over crossfade-1 so the last rendered frame lands at exactly the incoming tap instead of a residual step; corrects the CLAUDE.md invariant and seam test to match. Shares lerpSource/crossfadedSource/maxCrossfade, fixes stale docs/constants, and clears crossfade on the loop-OFF gesture.
Trigger's fade pair folds into the AHD (and goes live); the release anchors right;
Preserve rings its synthetic tail out instead of cutting it. Payload v10.
Replaces frozen-difference declick with bounded blend (out*(1-w)+ref*w, bounded by max(|ref|,|out|)). soundingNote() gates activePreserveVoices and mono-Legato retune away from ramp-only past-end voices. Magnitude-bound test asserts |v|<=1 across the ramp.
Default flat y=1 (R10-F1 Option A) replaces the linear velocity/127 at note-on — a deliberate, non-back-compat behavior change; v1-v6 blobs lift to the flat default.
keyTrackedRatio is bit-identical to pitchRatio at 100%; keyTrack threads through PerformanceZone->ResolvedZone->KeyZone into baseRatio_, so Varispeed and Preserve both inherit it. Zones payload bumped to v6; older blobs lift to 1.0.
Voice::start reads full zone ADSR instead of folding only holdFrames into instrument-wide gateAdsr. Wire format bumped to v4 (four new fields); v3 blobs lift A/D/S/R to kTier0Nominal* constants. Single-capture editor controls now reachable. Minor comment and geometry fixes.
Per-zone play params on SampleData; hand-rolled pure pitch_shift OLA for Preserve (WDL drags
windows.h); zone-payload v3 tail; RT-safe pre-warmed shifters + Preserve voice cap.
REAPER-free and VST3-free voice engine with bounded stealing, ADSR
envelope, key/velocity keymap resolution, and repitch from root note
with loop-point sustain. Test target links neither SDK.
