"MIDI" stands for Musical Instrument Digital Interface.  MIDI is simply musical instruments communicating with zeros and ones.

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