+midicopy new feature: -zerochannels will set all channel numbers in
+the midi file to zero. Some midi files (http://scarlatti.antikytherapubs.com/ )
+adjust the tuning by assigning each pitch class to a separate channel
+and applying an appropriate pitchbend to each of these channels.
+This may pose a problem for some software which attempts to render the
+midi file in music notation.
