# MidiBro Changelog

## [1.2.0] - 2025-08-31

### Added

- Ableton Link integration for bi-directional start/stop sync between MidiBro and DAW
- Progress bar animation improvements
- Timeseek in thumbnail/note pattern
- Seamless octave changes
- Enhanced detection of files for instrument 'flexible' collections
- New collection "Arpeggios & Sequencer"
- Performant and graceful handling of slow external drives like NAS
- Enhanced key detection with advanced filename analysis and fallback sophisticated algorithms
- Folder tree: shows tool tip with full folder path
- MIDI Input Pass-Through of plugin (if DAW allows)
- GUI right panel layout improvements:
  - Toggle button positioned closer to left separator
  - More compact spacing for play controls
  - Audio mode button renamed from "Plugin" to "Plugin in DAW"
  - Internal synth with presets (Bass, Piano, ...) - configurable via config.json file
- Menu entries:
  - "Debug logging" to toggle between log levels "INFO" and "DEBUG"
  - "Full scan" now reports corrupted files and creates a list
  - "Audio settings" to configure internal synth and Ableton Link
  - "Shrink Database" removes orphaned entries and optimizes indices
  - "Reveal folder w/ logfiles..." opens folder with logfiles, database and config.json

### Fixed
- Ghost entries showing after folder removal
- Removal of folders cleans up database
- More robust file scanning with two phases; first phase with progress bar, second phase async in background (see status bar)
- Rename or removed files can be updated using Full Scan (from menu)
- Star rating or octave change stopped playback
- Highlighted entry in central table now has orange font color (better readability)
- Menu entry names renamed to be more descriptive

### Know issues
- No codesigned app and plugin on MacOS (open installer & app with right click "open" first time); on older macOS plugins are maybe not showing
- AU plugin may not work (use internal synth instead)
- Sometimes you have to stop/click play after change plugin <-> internal synth
- "Reveal File" in Windows just opens folder, file not selected
- Adding folder from NAS may be slow or has issues (use local folders or USB drives instead)
- Thumbail pattern animation: changing tempo with Ableton Link enabled causes a transition phase until tempo is adjusted  (wordaround)
