This week's ALA Direct mentions of Andrew Bullen's C4LJ article:

"As an (admittedly amateur) local historian, it has been frustrating to be
presented with spectacular examples of sheet music that give shape and depth to
history yet be totally inept at playing the tunes on a piano or other musical
instrument. Happily, as it turns out, through a combination of Optical Music
Recognition (OMR) and music composing software, I can scan the music, 'read' it
to detect the notes, time signature, etc., and tweak its playback to get just
the right sound I want."...
