- main.cpp: drop transportStopped defer in handleOpenGui (G0.1 legacy);
G0.1b setReloading-before-job + single UiThread (G1.2) block the
2-thread-1-DLL race. GUI opens immediately during PLAY, short mute
(~0.1-0.3s first time, hasAttachedOnce_ false so reloadForGUI skips
reload); notes already sounding are kept. Reopen after close still
reloads (1-3s mute) - level 2 not feasible.
- app.jsx: remove !isPlayingRef.current guard before openNativeGUI in
loadTrackInstrumentToBridge.
- rebuild app.precompiled.js + daw_vst_bridge.exe.
- playMidiPreview standalone: thay soundfontRender backend (pyfluidsynth khong co
trong bundle -> 501 -> cam) bang playMediaExplorerBridgePreview: allocate
channel rieng, bridgeLoad SF2 + loadInstrument, CC0/CC32/PROGRAM, NOTE_ON/OFF
theo beat, loop timer; bridge down -> fallback WASM
- stopMediaPlayback: NOTE_OFF toan pitch cho channel preview de note khong con
ngan sau khi stop
- LOAD job posts WM_CLOSE to window created on main thread (DestroyWindow from worker crashed 0xc000041d, muting all tracks)
- handleOpenGui + attach jobs skip when Vst3Instrument::hasAttachedView() (state_ && guiAttached_)
- attach failure posts WM_CLOSE; post_close_gui erases entry only when it points at the same hwnd
- cap openVstGuiRetry at 5 to stop frontend retry spam
- native bridge: dedicated watchdog thread (parent death / PID-reuse via GetProcessTimes) -> TerminateProcess self; transportStopped flag drops note-on after STOP + CC64 sustain release + allNotesOff on stop
- tauri: set_bridge_child overwrites managed BridgeProcess state (app.manage is no-op when state exists) so Destroyed handler kills restarted bridge
- ui: stopAllPlayback syncs isPlayingRef/subTabsRef + second transport stop at 150ms; onStatusChange resets __bridgeLoadedChannels at callback start (auto-restart never emits bridge-down); openVstGuiRetry waits for async C++ load before OPEN_GUI; loadVstToBridge uses synth_engine.plugin_path / listPlugins fallback and persists plugin_path on load; shrink track-header Synth/GUI buttons
- preloadTrackInstruments: also load VST3 tracks into bridge (no GUI) on project open
- onStatusChange(connected): reload all VST tracks after bridge restart/down recovery
- GUI button (track strip + piano roll): ensure-load then open — no white window when bridge restarted and instrument gone
- __bridgeLoadedChannels map: skip reload if already loaded (avoids plugin state reset); reset on bridge down
- piano roll: wrap Synth+GUI buttons in shrink-0 row so GUI stays on same line; compact track-strip GUI button
- 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
Two guards: schedulePianoRollMidi skips native SF item scheduling while bridge is active; scheduleMidiNoteDispatch lets notes pass to the MIDI router when a piano-roll sub-tab is playing. Verified on Windows: SF2 peak 0.026, VST3 ACDD native GUI + peak 0.074 via Play button. Docs: TEST_NOTES.md, TASKS.md.
- bridgeAudioNode: ScriptProcessor 4096 drained only 1 of 16 blocks -> ~94% silence; now drains all queued blocks per callback, RING_DEPTH 8->24
- app.jsx: openNativeGUI had NO caller; wire after VST3 loadInstrument OK in track Synth dropdown + Plugin Manager Load Bridge
- main.cpp: OPEN_GUI polls up to 10s for LOAD completion (worker thread) before attach - fixes race 'no instrument loaded'
- index.html: bump bridgeAudioNode/app.precompiled cache versions
- render_engine: soundfont track không có plugin_id giờ vẫn dùng instrument sf2 thay vì rơi về wave synth
- fontawesome: sửa đường dẫn webfonts (bỏ ../) hết 404 icon
- media explorer: drag MIDI library items vào timeline tạo được midi item (sinh 6 MIDI loop mẫu + resolve drop file)
- app.jsx: 3 path gate window.SonicSF cho phép route playback qua SonicCarlaMidi
- Thêm ensureMasteringRouting() đồng bộ graph mastering + routing SF + route gains NGAY trước khi preview (keybed onMouseDown, playDrawPreview, playMidiPreview, mở piano roll tab) — hết phải bật/tắt nút power mới có tác dụng
- applyMasteringSettings sig thêm masterConnected/isBypassed — toggle power luôn re-apply tham số module
- Nut Synth TCP goi openInstrumentSelector (modal 'Select Instrument')
nhung modal chi co category SoundFont + GM - khong co muc VST (muc VST
chi ton tai o dropdown MixerStrip). Them 'VST Instruments' vao sidebar
trai modal: list instrumentSelectorData.vst_instruments (listPlugins),
click -> setTrackInstrumentWithUndo(trackId, v.id, v.name) + dong modal.
- _scan_vst_in_dirs + /scan: phat hien ca FOLDER ten X.vst3 (Windows VST3

Verify engine frozen: /plugins/available tra ['PadMachine','UltraSynth']

Trieu chung tu user: Task Manager day daw_engine process, port 8000->8005

Goc re: app/core/vst_engine.py module-level:
HAS_PEDALBOARD = check_pedalboard_safe()
-> subprocess.run([sys.executable, '-c', 'import pedalboard'], timeout=2.0)
Khi frozen, sys.executable = daw_engine.exe. PyInstaller bootloader bo qua
'-c' va chay script nhung (desktop_engine.py = CA ENGINE) -> moi lan check
thu vien lai khoi dong mot engine moi (timeout 2s moi check, block startup
~4s) -> engine con import app.main -> lai chay check -> spawn tiep
=> de quy vo han, hang chuc engine, may nghen, load 6-7.5s.
Fix:
- vst_engine: check_pedalboard_safe/check_pyfluidsynth_safe dung
importlib.util.find_spec (micro-giay, khong spawn, hoat dong frozen).
- desktop_engine.main(): guard phong thu - neu bi goi voi argv[1]=='-c'
(dang bi dung nhu python interpreter) thi thoat ngay khong chay server.
Verify tren Linux (engine frozen):
- STARTUP: 6-7.5s -> 1.24-1.33s (3 lan lien tiep)
- sau 15s: dung 1 engine, 0 process '-c import' (truoc: hang chuc)
- 86 tests pass; test suite 34s -> 14s (may het bi spam).
