Musical Instrument Digital Interface
     
         (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".
