Params ride the one parameter set; payload v8 -> v9, off by default.
Deck composition moves to a pure deck_groups module in pitch -> filter -> amp order.
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.
New top-level previewVelocity field (MIDI 1..127, mid default 64), sibling of
channelMode. Envelope bumped v5->v6; v5 and older blobs lift to the mid default.
Zones payload untouched (independent version axis). Round-trip + v5/v4-lift +
truncation tests added.
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.
kLegacyV3NominalRate removed. readZonesPayload, deserializePerformance, deserializeComponentState now take a projectRate for v3 frames→seconds. Rate fields default 0 (invalid). Four 44100 fallbacks replaced with assert+safe-return. 96k v3-lift test added.
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.
Extension stamps a monotonic bank_generation counter, bumped at content
mutations; the VST3 instrument polls it off-thread on an editor timer and
consumes assignment requests, refreshing playback hands-free.
Zone editor in the IPlugView LICE surface, zoned resolution built off-thread into the
LoadedInstrument keymap with Tier-0 fallback, performance map in VST3 component state
with v1 back-compat. Pure resolve/build/serialize + geometry with CTest coverage.
Tag LoadedInstrument with installedAt; process() publishes that field (not a re-read
of reloadGeneration_) so the pruner's displacedAt <= seen bound is airtight. Also fixes
sampleRowHitTest canvas.bottom over-read and adds interleave-stride + canvas-clip tests.
