Changing to # or b for entire song

Why not a simple way to useModifier() for ChordProParser() object directly?

Great feature! Putting this on the board!

I combined ChordFiddle example into a single function, but would be great to support it natively.

The following is the member function to update modifier for this.song ChordSheetJS.Song() object.

public setFixChordModifier(modifier: Modifier): void {
  let processedSong = this.song.clone();
  processedSong.lines = processedSong.lines.map((line) => {
    const processedLine = line.clone();
    processedLine.items = line.items.map((item) => {
      if (item instanceof ChordSheetJS.ChordLyricsPair && item.chords) {
        let processedChordLyricsPair = item.clone();
        if (item.chords) {
          let parsedChord = Chord.parse(item.chords);               
          if (parsedChord) {
            processedChordLyricsPair.chords = (new Chord(parsedChord).useModifier(modifier)).toString();
            processedChordLyricsPair.chords = processedChordLyricsPair.chords.replace('B#', 'C');
            processedChordLyricsPair.chords = processedChordLyricsPair.chords.replace('Cb', 'B');
            processedChordLyricsPair.chords = processedChordLyricsPair.chords.replace('E#', 'F');
            processedChordLyricsPair.chords = processedChordLyricsPair.chords.replace('Fb', 'E');
            return processedChordLyricsPair;
          }
        } else {
          return processedChordLyricsPair;
        }
      }
      return item;
    });
    return processedLine;
  });
  this.song = processedSong;
}

Hey @beltonk. I just published 10.3.0, which includes this feature: song.useModifier(modifier).
