MIDI (Musical Instrument Digital Interface; IPA: /ˈmɪdi/) is an industry-standard protocol that enables electronic musical instruments, computers and other equipment to communicate, control and synchronize with each other.MIDI does not transmit an audio signal or media — it simply transmits digital data "event messages" such as the  pitch and intensity of musical notes to play, control signals for parameters such as volume, vibrato and panning, cues and clock signals to set the tempo. As an electronic protocol, it is notable for its success, both in its widespread adoption throughout the industry, and in remaining essentially unchanged in the face of technological developments since its introduction in 1983.
