- Use filter(t => t.isArmed) instead of find() to route
MIDI input to ALL armed tracks simultaneously
- Use getTrackMidiChannel per track instead of raw
MIDI hardware channel (msg.data[0] & 0x0F)
- NoteOff, CC, PitchBend also routed to each armed
track's dedicated channel
- Previous code sent to channel 0 + first armed track only
Line 5273 called playNote with undefined program + no channel,
defaulting to channel 0 with last-set instrument (may be Track 2's).
Fix: resolve parent track from st.trackId, pass correct channel
and synth_engine/instrumentProgram.
6 call sites were missing channel parameter, causing FluidSynth
to use ch=0 for all tracks -> program_change on channel 0
overwrote instrument across tracks during playback.
Fixes: startTrackPlayback, section sub-track MIDI, playMidiPreviewNote,
piano roll Alt+scroll preview, note click preview, keybed preview.
When midiChannel is undefined (no instrument set), compute channel
from track index to avoid defaulting to 0 and clashing with
configured tracks that use channel 0.
- setTrackInstrumentWithProgram stores midiChannel on the track
- schedulePianoRollMidi reads track.midiChannel instead of
recomputing from index (can be inconsistent across calls)
- selectInstrument also stores midiChannel if not already set
- isLooping defaults to true on subTab creation (auto-loop when
range selection is set)
- Per-track instrument confirmed: selectInstrument respects passed
channel, _playNoteFluid bypasses _engineChMap when channel is
explicit, no-instrument fallback sets program 0 (default piano)
instead of inheriting another track's program
- When activePlayTrackIds is null (no button selected): no ghost play
- When activePlayTrackIds is set (one button red): only that track's
ghost notes play, with the track's own instrument on its own channel
- Removed st.currentTime >= 0 check from playhead rendering
- handleEditMidiInTab: currentTime = -beatOff * beatSec so phBeat=0
- handleSwitchMidiItem: same logic for dropdown switches
- Playhead draws at x=0 (bar 0) when item opens, moves right during
playback from the initial negative position
When selectedNoteIds.length > 0, shift+scroll on any note changes
velocity for all selected notes. Also fixed hit-test to subtract
renderBeatOffset for correct positioning in session mode.
handleEditMidiInTab now sets currentTime relative to item start:
currentTime = Math.max(0, mainTimelineCurrentTime - midiItem.startTime)
so playhead reflects the main timeline position instead of bar 0.
handleSwitchMidiItem now computes new currentTime from the delta
between old and new renderBeatOffset, keeping the playhead at
the same session-absolute time instead of resetting to bar 0.
When activePlayTrackIds was null (default: all play), clicking a track
created an empty Set and deleted nothing. Now initializes with all
track IDs, so click toggles the clicked track off/on correctly.
- Remove dashed border from ghost notes (fill-only at 25% opacity)
- Track column: replaced div overlay with natural flex child; use
<button> elements with border-l-2 indicator; removed pointer-events
- Ghost playback: skip layers with no instrument assigned (silent)
instead of playing with default piano
- Track column: centered 12px buttons, purple active / yellow highlight
- Ghost playback: ghostLayers synced to st.ghostPlayLayers via useEffect;
schedulePianoRollMidi plays ghost notes from active tracks
- Per-track MIDI channels: each track gets a unique channel based on
its index, enabling separate instruments per track
renderBeatOffset was in bars but used as beat offset in rendering.
Multiplying by timeSigNum=4 converts to beats so items appear at
correct session-absolute positions.
- handleSwitchMidiItem no longer saves/sets previous item as ghost
- Removed ghostTrackFilter/filteredGhostLayers
- Track column shows clickable track names that toggle play state
- activePlayTrackIds Set controls which tracks' MIDI are playable
- Context menu flips upward near viewport bottom edge
- Track column (120px) left of keybed: checkboxes per track to
filter ghost notes; active track highlighted
- Session mode: canvas extends to full session duration
- Filtered ghost layers via ghostTrackFilter state (Set of track IDs)
- Fixed bar label seek in session mode (was using wrong offset)
- MIDI ghost notes: all non-selected items rendered at 25% opacity
- Dropdown at tab title: switch active edit target across all tracks
- Session Sync mode (default): viewport aligned to session bars
- Isolated mode toggle: bar 0, no ghost notes
- Ghost toggle: show/hide ghost layer (only in session mode)
- Auto-scroll to session position in session sync mode
- Bar labels show absolute session bar numbers
- Track sustain state per channel via _sustainStates[]
- sustainActive(channel) returns boolean
- MIDI NoteOn: only send CC123 if !sustainActive(ch)
- Preserves sustained notes when playing new notes
- NoteOn: durationMs=60000 (1 phút, giữ cho đến khi NoteOff)
- NoteOff: stopNote(ch, pitch) gọi synthInstance.noteOff() ngay
- MIDI channel (msg.data[0] & 0x0F) truyền đúng vào playNote
- CC (sustain/modulation) + pitch bend forward qua SpessaSynth
- Add controllerChange forwarder for all CC messages (cmd 0xB)
- Add pitchBend method to SonicSF + MIDI handler (cmd 0xE)
- CCs routed to _synthInstance.controllerChange(ch, cc, val)
- Pitch bend routed to _synthInstance.pitchBend(ch, 14bit-val)
- Remove small Synth button (already done earlier)
- Large Synth button now calls openInstrumentSelector (instrument modal)
- Fix _initPromise stale cache: reset to null when init fails
- Module not loaded yet → retries on next select instead of stuck
- openInstrumentSelector builds flat list of all instrument presets
- Modal shows all instruments with search bar
- Each preset shows sf name + program name
- Remove old two-step (SF list -> presets) navigation
- Fix pre-existing closing paren mismatch in PluginManagerModal
- catalog keys are lowercased (soundfont_inspector: .lower())
- sf.id from _scan_soundfonts has original case (SGM_v2.01)
- Use catalog[sfId.toLowerCase()] || catalog[sfId] to match both
- _scan_soundfonts: dict-keyed by base_id to prevent duplicates
- Add 'source' field ('system' | 'upload') to each soundfont entry
- Delete endpoint: only allow deleting upload soundfonts (403 for system)
- Frontend: show (system)/(upload) tag, hide Delete for system fonts
- App startup fetches full catalog with all instrument presets
- Merges presets into instrumentSelectorData.soundfonts
- Synth button shows presets from cache (no per-SF API call)
- Fallback: if cache miss, fetch individual SF presets on demand
- Remove setSelectionStart/End from simple click (non-drag) path
- Only handleMouseMove (drag) creates/modifies selection
- Sub-tab already correct (no selection set on click)
- Time Ruler click → setSelectionFollowsTempo(false) → time-based
- Tempo Track Lane click → setSelectionFollowsTempo(true) → tempo-based
- Also handles sub-tab ruler (EDITOR tabs)
- Manual toggle button ♪T/⏱T still works for override
- WaveformLane bar grid: integer beat loop (bn*beatDuration) instead
of accumulating t += beatDuration — no floating point drift
- Add selectionFollowsTempo toggle button (♪T/⏱T) in transport bar
- ♪T (tempo): selection recalculates with BPM
- ⏱T (time): selection fixed in seconds regardless of BPM
- TimelineRuler draws bar lines at bn * barDuration positions
- Same integer beat loop as TempoTrackLane (bn from firstBarNum)
- Bar number labels at center of ruler
- Time markers still shown below bar markers
- All use same bpm prop → always aligned with tempo track
- Replace t += beatDuration loop (floating accumulation drifts)
- Iterate by integer beat number: t = bn * beatDuration
- Each bar position computed independently, no cumulative error
- Same fix for snapInterval loop
- Fixes unequal bar widths for BPM like 77, 81
