MIDI Interface Bus; [Musical Instrument Digital Interface]:
MIDI defines the electrical and physical interface over a 5-pin DIN connector, on a 64 ohm cable.
MIDI also defines the protocol used over the interface, which happen to be digital instructions and not music.

The MIDI interface uses three different pinouts which are all defined on a 5-pin DIN connector;
MIDI In, MIDI Out, and MIDI Thru.
