Songbird DAW — Work In Progress

​

Bug Fixes

• Stock plugins UI not loading in release build — May be fixed (see release build investigation). Needs manual verification in a release build with ./utils/build.sh.
• Loop position resets — Fixed: processTrackNotes() in store.ts now only updates transport state when values actually change, preventing unnecessary overwrites.
• MIDI editor drag selection square not visible — Fixed: Canvas redraws immediately during selection drag via requestAnimationFrame in MidiEditor.tsx.
• Duplicate MIDI notes — Added: Press Cmd+D (Mac) / Ctrl+D (Windows) to duplicate selected notes. Duplicated notes placed immediately after the selection.
• Arrangement clip selection bubble missing — Fixed: MIDI clips in arrangement view now show a selection outline when Shift+clicked.
• Track header hover buttons not hiding — Fixed: Wrapper container correctly manages hover states and pointer events for Expand/Mute/Solo buttons.
• Plugin order reversed — Fixed: Stock plugins (reverb, channel strip) now open in the correct order from the mixer.

New Features to Test

​

Collaboration

• Create a collab room — Start server with ./utils/collab-server.sh, create room in the Collaboration panel, verify invite code is generated.
• Join a collab room — Second instance joins with invite code, verify project files are received.
• Push/pull sync — Edit notes on one instance, verify changes appear on the other after auto-sync.
• Bird file merge — Two users edit different tracks in the same section, verify auto-merge works.
• JSON state merge — Two users adjust different mixer controls, verify both changes are applied.
• Presence — Verify peer join/leave notifications appear in the activity feed.

​

Plugin Compatibility

• Missing plugin detection — Load a project referencing a plugin you don’t have, verify the PluginCompatibilityModal appears.
• Best Match substitution — Click “Best Match” for a missing plugin, verify category-based fallback selects an appropriate substitute.
• Runtime-only substitutions — Verify substitutions are not saved to the .bird file (close and reopen should re-trigger the modal).

​

Application Lifecycle

• CrashGuard — Force-quit during plugin loading, verify sandbox mode auto-enables on next launch.
• Recent projects — Open several projects, verify the project picker shows them ordered by last-opened, capped at 10.
• Settings centralization — Verify all settings (API key, MIDI device, theme, Middle C reference) persist in ~/.songbird/settings.json.

​

MIDI Editor

• Ghost notes — Open a track in the piano roll, verify notes from other tracks appear as translucent “ghost” notes.
• Section editing — Click the edit button on an arrangement section, verify name and length can be modified.

​

Build & Validation

• ./utils/validate.sh — Run full validation suite, verify all 4 steps pass (C++ tests, TypeScript, ESLint, Vitest).
• ./utils/build.sh — Run release build script, verify it produces a codesigned .app.
• ./utils/validate.sh cpp — Run only C++ integration tests, verify they pass headlessly.
• ./utils/validate.sh vitest — Run only Vitest tests, verify all store/slice tests pass.

​

AI Copilot

• Improved intent routing — Test EQ and channel strip operations, verify AI routes to correct tools.
• Granular commit messages — Make an AI-driven edit, verify the commit message describes the specific changes (not generic “LLM edit”).

​

Sentry (Needs Setup)

• React Sentry — Uncomment sentry.ts, provide DSN, verify errors are reported from the WebView.
• C++ Sentry — Uncomment sentry-native in CMakeLists.txt and Main.cpp, verify native crash reports.

​

Sample Editor

• Enhanced sample editor — Load an audio track, verify waveform display and editing improvements work correctly.
