- MIDI stands for Musical Instrument Digital Interface. MIDI is a file format and protocol for communicating between devices. MIDI is used to send digital data about music between devices, rather than the resulting analogue sound.
- A digital instrument (MIDI) sound file does not store samples. Like a vector graphic, a MIDI file is a set of instructions that is used to play music. Each note has attributes (sound, length, volume, time etc) that place it into the sequence of notes in the file. MIDI files can be played back by a computer using its own digital instruments.
