    • Dissonance vs. Sentiment Polarity


  • MusicXML Processing:
    • Minor seventh (m7) chords are now correctly exported to MusicXML
    • Fixed export of lyric syllables that are extended across multiple notes
    • Fixed issue where lyric syllables were repeated if notes were divided (e.g. across a bar line)
    • Previously it was not possible to tie more than two notes rhythmically when exporting to MusicXML. This issue has been fixed.
  • Miscellaneous Fixes:
    • Fixed a NullPointerException during automatic detection of external applications that occurred on Windows systems in case of insufficient file system permissions
    • Fixed an IndexOutOfBoundsException when generating scores with the fret board diagram option disabled and no fret board instrument selected
