RVRSE 1.0.0

Added

• macOS: ad-hoc codesign (codesign --force --deep -s -) all bundles (VST3, AU, CLAP, standalone) in CI before packaging — prevents Gatekeeper "damaged" error on downloaded builds (rverse-wix)
• Version sync script (scripts/sync-version.py) — reads canonical version from config.h and propagates to all plists, Inno Setup installer, and CMakeLists.txt; CI check mode (--check) prevents version drift (rverse-jaj)
• Pluginval validation in CI — VST3 validated on both platforms, AU on macOS; strictness level 5, hard gate on failure (rverse-nwe)
• Full IGraphics GUI with dark theme (dark green/blue palette, gold/blue accents) — responsive layout with corner resizer (rverse-ebv)
• Dual waveform display: riser (gold) + hit (blue) with shared amplitude normalization and animated playhead (rverse-ebv)
• Hit preview waveform in hit panel showing original loaded sample (rverse-ebv)
• Riser panel: real-time section (Stutter Rate, Stutter Depth, Riser Volume — gold knobs) + offline section (Lush, Riser Length, Fade In — steel knobs, Stretch Quality toggle) (rverse-ebv)
• Hit panel: volume knob (blue accent), hit waveform preview, logo, donate/support button (rverse-ebv)

Changed

• Replaced all AcmeInc placeholder branding with SamuFL identity across plists, installer files, and config (rverse-g67)
• Updated user-facing URL to https://samufl.com and contact email to info@samufl.com (rverse-g67)
• Updated config.h and related metadata toward the 0.1.0 release version (rverse-g67)
• Debug Stage parameter hidden/disabled in release builds via #ifndef NDEBUG while its parameter slot remains reserved for index stability — intermediate pipeline buffers no longer allocated in release (rverse-0v6.1)
• Header zone: plugin title, Load Sample button with native file dialog, sample info display, BPM display (rverse-ebv)
• Footer zone: master volume slider with label/value, MIDI activity indicator (blue dot), version string (rverse-ebv)
• Resize support: corner resizer with smart layout scaling — waveform absorbs squeeze, panels maintain minimum heights (rverse-ebv)
• Stretch Quality parameter (High / Low) — defaults to High for best audio quality; Low mode (~2× faster) available for real-time tweaking or resource-limited systems (rverse-g4j)
• Riser Length is now a discrete parameter with 7 musical values (1/4, 1/2, 1, 2, 4, 8, 16 beats) instead of continuous 0.25–16 range — snaps to exact beat divisions (rverse-ebv)
• Replaced OLA time-stretcher with signalsmith-stretch (MIT, spectral, polyphonic-aware) for significantly better audio quality at all stretch ratios — transient smearing at riser end eliminated (rverse-g4j)
• Stretch-only rebuilds (riser length, BPM changes) run synchronously during offline/bounce rendering so automation is respected immediately; async during real-time playback (rverse-g4j)

Fixed

• AUv3 Framework plists (iOS + macOS) had stale version strings (1.0/1.0.0 instead of 0.1.0) — now synced via sync-version.py (rverse-jaj)
• CMakeLists.txt project version was 1.0.0 instead of 0.1.0 — now synced (rverse-jaj)
• AU plists had stale iPlug2 template values: type was aufx (effect) instead of aumu (instrument), subtype was 9c0G instead of 5SpI matching config.h PLUG_UNIQUE_ID — caused pluginval Class Data mismatch failure (rverse-nwe)
• Plugin GUI crash (SIGABRT in NanoVG font rendering) caused by missing font resource in deployed VST3/AU bundles — switched macOS non-Xcode deployment from COPY to SYMLINK to avoid iPlug2 resource bundling race condition (pre-existing bug)
• MIDI CC1 (Stutter Rate) and CC11 (Stutter Depth) now update both the DSP parameter and the GUI knob in real-time — previously GetParam()->Set() was called without SendParameterValueFromAPI(), so the knobs didn't move; stutter values are now read per-sample after MIDI processing for immediate response (rverse-y5o)
• VST3: MIDI CC knob updates now work correctly — SendParameterValueFromAPI() queue is not consumed in VST3 OnTimer(); replaced with a custom lock-free IPlugQueue<ParamTuple> pushed from the audio thread and drained in OnIdle() via SendParameterValueFromDelegate(), which works for all plugin formats (rverse-f9r)
• Riser-to-hit transition smoothed with adaptive overlap — at low stretch ratios the riser extends 1/32 beat past the boundary; at high stretch ratios the overlap scales proportionally (up to 1 beat) so the smeared transient tail crossfades smoothly into the hit attack; the tail fade also scales to cover the full overlap (rverse-0g6, rverse-xwx)

Added

• Persist loaded sample path across DAW sessions — save/restore via SerializeState/UnserializeState with versioned chunk format. Shows "Missing: filename" if file is gone on reload. (rverse-7dr)
• GitHub Actions CI: macOS (Apple Silicon, Ninja) + Windows (VS2022) — builds all plugin formats and runs 42 unit tests on pushes to develop/main and PRs targeting them (rverse-lxg)
• Artifact publishing: rolling develop-latest pre-release (Debug zips) on develop push, and proper GitHub Release (Release zips) on v* tags — macOS + Windows per-platform downloads (rverse-6m5)
• Expose 5 new DAW-automatable parameters via generic editor: Lush (0–100%), Riser Length (0.25–16 beats), Fade In (0–100%), Riser Volume (-60 to +6 dB), Hit Volume (-60 to +6 dB) (rverse-nqg)
• Debug Stage parameter (Normal / Reverbed / Reversed / Riser Only) — exposes intermediate pipeline buffers for diagnostic playback without hit (rverse-l9x)
• Riser fade-in envelope controlled by Fade In parameter — linear ramp over configurable portion of riser length (rverse-nqg)
• Independent Riser Volume and Hit Volume knobs with dB scaling — both voices fully controllable (rverse-nqg)
• Lush and Riser Length changes propagated to offline pipeline in real-time — riser rebuilds on parameter change (rverse-nqg)
• DSP unit tests: 42 tests across 7 files covering BufferUtils, Reverb, TimeStretch, Stutter, SampleLoader, and Constants (rverse-2uq)
• trimTrailingSilence / trimTrailingSilenceStereo in BufferUtils.h — removes near-silent tail samples below a configurable threshold (rverse-0d0)
• kReverbTailSeconds (5.0s) and kSilenceThreshold (-30 dB) constants in Constants.h (rverse-0d0)
• Catch2 v3.7.1 test framework with CTest integration — cmake --build build --target rvrse_tests && ctest --test-dir build (rverse-6fl)
• Smoke tests for DSP headers: Constants, BufferUtils, TimeStretch, Stutter (rverse-6fl)
• Real-time stutter gate in Stutter.h — per-sample trapezoidal gate with continuous Hz rate (0–30 Hz) and anti-click ramps (rverse-n84)
• Stutter Rate (Hz) and Stutter Depth exposed as DAW-automatable parameters (rverse-n84)
• MIDI CC control: CC1 (mod wheel) → Stutter Rate, CC11 (expression) → Stutter Depth (rverse-6r2)
• Git hooks: commit-msg (beads ID enforcement), pre-commit (conflict markers, secrets), pre-push (git-flow protection) (rverse-e1u)
• Riser + hit dual-voice playback: note-on plays reverse-reverb riser, dry hit fires at beat offset (rverse-djb)
• Offline-to-realtime handoff: RvrseProcessor wired into RVRSE class with lock-free riser buffer consumption (rverse-1na)
• RvrseProcessor.h — offline pipeline orchestrator: reverb → reverse → stretch with generation-based abort and cached intermediate buffers (rverse-62q)
• TimeStretch.h — OLA time-stretcher with Hann windowing + calcStretchFactor() helper (rverse-07s)
• BufferUtils.h — in-place stereo buffer reversal, linear resampling, tail fade-out utilities (rverse-cmf)

Fixed

• Installer license.rtf replaced with actual MIT license — was iPlug2 placeholder with no legal basis (rverse-jwf)
• Critical: Reverb tail was truncated — output buffer was same size as input, producing no reverb tail. Now pads source with 5 seconds of silence so the Schroeder reverb rings out naturally, then trims trailing silence. This is the core of the reverse-reverb effect. (rverse-0d0)
• Hit sample now resampled to DAW output rate on load — fixes pitched-down playback with 96kHz+ files (rverse-djb)
• Offline pipeline resamples source to output rate before processing — riser length now correct regardless of file sample rate (rverse-djb)
• Riser tail fade-out (1/16 beat) prevents reversed transient from clashing with hit (rverse-djb)
• Hit no longer re-triggers on MIDI note-off — mSamplesFromNoteOn counter now reset (rverse-djb)
• Host BPM now read via GetTempo() and propagated to offline pipeline — riser re-stretches on tempo change (rverse-djb)
• kMaxSampleFrames now supports up to 192kHz files (was limited to 48kHz) (rverse-djb)
• Schroeder/Moorer algorithmic reverb in Reverb.h — 8 parallel comb filters feeding 4 series allpasses (rverse-6el)
• applyReverb() and applyReverbStereo() stateless functions for the offline pipeline
• Reverb constants in Constants.h — room size, feedback, damping, allpass gain
• MIDI note-on triggers sample playback with velocity scaling (rverse-p38)
• Sample-accurate MIDI timing via IMidiQueue
• 5ms note-off fade-out envelope (anti-click)
• Sample loading via dr_libs (WAV + AIFF support) (rverse-g1x)
• SampleData.h — deinterleaved stereo float32 sample buffer struct
• SampleLoader.h/.cpp — stateless offline loading functions
• "LOAD SAMPLE" button in GUI with native file dialog
• Sample info display (filename, sample rate, channels, duration)
• dr_libs headers (dr_wav.h, dr_flac.h) in RVRSE/libs/dr_libs/
• iPlug2OOS project scaffold with CMake build (rverse-03y)
• Plugin configured as MIDI instrument (VST3 / AU / CLAP)
• Dark-themed placeholder GUI with RVRSE title
• Constants.h with all MIDI CC defaults and parameter ranges
