- Replace currentTime with auto-calculated maxEnd from existing items
- Each AI generation starts right after the previous one
- Ensures tracks from different generations align in bar columns
- Build synth_engine object with type, plugin_id, soundfont_bank,
soundfont_program, soundfont_id
- Save to targetTrack.synth_engine so schedulePianoRollMidi reads it
- Pass synthEngine as 3rd arg to applyAITrackInstrument (was missing)
- Remove redundant separate loadSoundFont call (applyAITrackInstrument
chains to selectInstrument which already calls loadSoundFont)
- Wrap TimelineRuler + TempoTrackLane in sticky-top div
- Same sticky pattern for both main session and sub-tab views
- TCP column already has sticky header (top-0) and tempo row (top-10)
- Background color hides tracks scrolling behind ruler
- Transport Loop button now syncs isLooping with active sub-tab
- Auto-computes loopEnd from midi notes, section clips, or audio duration
- Sub-tab selectionStart=0, selectionEnd=computed boundary on loop enable
- Main timeline also auto-derives loop end from track items/clips
- All three tab types: MAIN SESSION, SECTION-TAB, PIANO ROLL
- Frontend serialize: use undefined instead of null for synth_engine
- Backend validate: strip None synth_engine from tracks before schema validation
- Prevents 'None is not of type object' schema error
- getAudioContext() calls SonicSF.init on every call (not just first)
- soundfontPlayer.init retries after 1s if SpessaSynth module not loaded yet
- Auto-loads sgm_v2.01 SF3 on successful init
- Fixes race condition: module script loads after regular scripts
- Remove small Synth button between ARM and Monitor (duplicate)
- Remove empty try/catch that swallowed all MIDI handler errors
- Ensure MIDI keyboard passes synth_engine context to playNote
- Direct fallback to armed main track when no PIANO_ROLL sub-tab armed
When MIDI note-on received and no PIANO_ROLL sub-tab is armed,
fallback to armed track in main session. Read its synth_engine and
instrumentProgram to route audio through correct instrument.
Route to track gainNode if available.
Add sfPresetSearchQuery state + search input in instrument selector
modal. Filters sfPresets by name (case-insensitive) when user types.
Clear search on SoundFont switch / modal close.
- toggleTrackDrum: sets is_percussion + soundfont_bank=128
- 🥁 button in track control panel (between Solo and Record)
- Shows 'D' badge when active, routes to MIDI channel 9
- Instrument preset list shows 🥁 prefix for bank=128 presets
- _find_sf2_path now case-insensitive to match catalog IDs
- serializeTracksList includes synth_engine, soundfont_id, instrument_source
- deserializeTracksList restores synth_engine and soundfont_id
- Add seekPlaybackTo(time) that stops, updates refs, reschedules
MIDI, and restarts playback for both sub-tab and main timeline
- 'Quay lại đầu' and 'Đầu vùng chọn' buttons use seekPlaybackTo
- Sub-tab selection loop only active when st.isLooping is true
- End-of-playback loop uses st.isLooping, not global isLoopingSelection
- SonicSF.stopAll() sets gain 0 and stops oscillators immediately
- Piano roll ruler click during playback now seeks and continues playing
- ADSR envelope uses linearRampToValueAtTime for crack-free release
- stopAll ramps gain to 0 in 20ms before stopping oscillators
