MIDI • stands for Musical Instrument Digital Interface. It is an agreed protocol from the early 80s that allows computers, digital musical instruments and other hardware to communicate musical instructions, regardless of manufacturer. • Unlike other audio formats that transmit representations of musical sounds, MIDI only stores or transmits commands about the music (the notes etc), and not audio signals.
