midi - Computer Definition
(Musical Instrument Digital Interface) A standard protocol for the interchange of musical information between musical instruments, synthesizers and computers. MIDI was developed to allow the keyboard of one synthesizer to play notes generated by another. It defines codes for musical notes as well as button, dial and pedal adjustments, and MIDI control messages can orchestrate a series of synthesizers, each playing a part of the musical score. MIDI Version 1.0 was introduced in 1983. Not Sound, The Notes MIDI does not record analog sound waves like a tape recorder. MIDI encodes keyboard functions, which includes the start of a note, its pitch, length, volume and musical attributes, such as vibrato. As a result, MIDI files take up considerably less space than digitized sound files. Since the advent of the General MIDI standard for musical instruments, MIDI has been widely used for music backgrounds in multimedia applications due to its space-saving feature. It is MIDI technology you might be hearing as the latest mobile ring tone or on a thrill ride or attraction at a theme park. However, MIDI is only for music, not voice. See General MIDI. Editing Is Different MIDI recordings are edited in an entirely different manner than conventional recording; for example, the rhythm can be changed by editing the timing codes in the MIDI messages. In addition, the computer can easily transpose a performance from B major into D major. Such editing would be virtually impossible with recorded sound waves. For more information, visit www.midi.org.
