Musical Instrument Digital Interface

(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

The Musical Instrument Digital Interface, popularly known as MIDI, had been in existence for several years before his talk, but it has been much more recently that readily available periodicals, such as Electronic Musician, and books, such as the one under review, have enabled libraries to provide support for persons interested in music technology in ways that were not possible in the mid- 1980s.
