1) wavesynth tự phát khi mở app: probe calibrate() render vào live mix
(renderAll process cùng instance) -> thêm calibratingCh_[16], renderAll
bỏ qua channel đang calibrate; plugin_host panic (sustain off + all
notes off + 128 noteOff) ngay sau preset apply để startup im lặng.
2) bấm GUI mở 2 cửa sổ Qin: sandbox VST2 child tự sở hữu top-level window
-> ownsGuiWindow() + main.cpp forward OPEN_GUI control, không tạo native
parent / không registry double-open.
3) play phát nhạc cụ sai: restore clobber — seed preset đè patch thật trong
state file (ch3 63ba3667 -> 7f07473c) do saveStateJob chạy lúc child còn
seed. Fix: queuePreset(waitApply=true) chờ child apply xong (presetOut
memcmp), consume-before-apply (zero presetInLen trước khi apply), deferred
double-load re-check trong main.cpp skip assign trùng path, watchdog
respawn re-queue lastPreset_.
- Fix A (USER32 crash): WM_CLOSE no longer destroys the native VST
window from the main thread (plugin editor children live on the
channel worker thread). WM_CLOSE -> hide + closeGUI on worker;
WM_DESTROY erases registry. LOAD_INSTRUMENT close uses closeGUI +
SW_HIDE, waits on hasAttachedView() instead of registry erase.
- Fix B: per-process SHM name SonicForge_DAW_IPC_{pid} so stale
bridges from old builds can never attach to a new app's ring buffer.
- Fix C (stall): opening editor for a plugin whose other channel still
has a live instance of the same DLL (Nexus) deadlocked the audio
loop (reload+createView on worker while audio thread processed the
other instance). Silence same-path channels via setReloading during
reload/attach, restore afterwards; audio resumes.
- Rebuild bridge + update install/ portable package.
- Close other channels' editor windows before attaching a new one (Option B)
- needsReload()/setReloading() guard: skip processAudioBlock during
terminate+reload teardown to avoid UAF/hang when reopening GUI
- Wait for editor registry cleanup (5s timeout) before creating window
- NativeInstrumentEngine: track GM bank per channel (CC0/CC32), use bank in programChange
- app.jsx: send CC0/CC32+PROGRAM before notes via __ensureBridgeProgram, dedupe, clear dedupe after async LOAD
- audioRoutingEngine/bridgeAudioNode: idempotent connect (no disconnect-flush on re-connect), fixes note cut & multi-track stuck
- main.cpp: remove 10s poll in OPEN_GUI control job (blocked realtime loop, watchdog race), VstWindowProc stores channel not inst pointer, cleanup gui maps on WM_DESTROY
