Here's another one that flips the song between major/minor. Make sure you have the right key selected first since auto-detect will always detect major.

Code:

if (keySelect.selectedIndex == 0) {
   message('Select a key first');
} else {
   var inverseKeyIndex = (keySelect.selectedIndex + 12) % 24;
   var inverseKey = settings.scales[inverseKeyIndex];
   for (i = 0; i < song.notes.length; i++) {
      var note = song.notes[i];
      var octave = note.type.substring(note.type.length-1);
      var noteInverseKeyIndex = scale.indexOf(note.type.substring(0, note.type.length-1));
      if (noteInverseKeyIndex != -1) {
          song.moveNote(note, note.instrument, note.instrument, note.time, note.time, note.type, inverseKey[noteInverseKeyIndex] + octave);
          song.update(note);
      }
   }
   keySelect.selectedIndex = inverseKeyIndex;
   keySelect.onchange();
}

Do you think you could make this so it doesn't affect percussion?
