According to the release notes, two sets of sharp/flat notes are supposed to be different colors or shades of a color. Unless I've suddenly gone colorblind, I don't see any difference in the shades for Gb, Ab, Bb, and Db, Eb.
Am I missing something?
I was stumped too...
It's the background sharps and flats underlying the actual midi notes of the song.
