MIDI

   <music, hardware, protocol, file format> (MIDI /mi'-dee/,
   /mee'-dee/) A {hardware} specification and {protocol} used to
   communicate note and effect information between synthesisers,
   computers, music keyboards, controllers, and other electronic
   music devices.  It is basically a high-speed {serial}
   connection with separate connections for MIDI in, MIDI out and
   MIDI through (to allow devices to be chained).

   The basic unit of information is a "note on/off" event which
   includes a note number (pitch) and key velocity (loudness).
   There are many other message types for events such as pitch
   bend, patch changes and synthesizer-specific events for
   loading new patches etc.

   There is a file format for expressing MIDI data which is like
   a dump of data sent over a MIDI port.

   The {MIME} type "audio/midi" isn't actually registered so it
   should probably be "audio/x-midi".

   {Filename} {extension}: .mid or .midi
