MIDI (was: Music duration)

[Kurt Kaufman]

*This is the MIDI file format reference I used when first learning  
about MIDI:
http://jedi.ks.uiuc.edu/~johns/links/music/midifile.htm

*This also seems useful, especially in describing the MIDI byte  
structure:

*You don't have to provide data for all possible parameters.  For  
instance, MIDI Builder does not indicate a specific velocity  
(loudness) for each MIDI note event. It just sets the value at 64 (mid  
range) and leaves it.  If we were using a velocity-sensitive input  
device, i.e. a touch sensitive MIDI keyboard controller, then we would  
want to "trap" the value of the velocity for each note.

*Print out the transcript dictionary reference for binaryEncode. Look  
especially at the H parameter.
