.MIDI File

File extension midi is commonly used for MIDI music files. Musical Instrument Digital Interface (MIDI) is a standard protocol for the interchange of musical information between musical instruments, synthesizers, and computers. This standard defines the codes for a musical event that include the start of a note, its pitch, length, volume, and musical attributes, such as vibrato. It also defines codes for various button, dial, and pedal adjustments that are used on synthesizers.

MIDI is a system containing music related commands for a synthesizer or other MIDI-compliant device. A MIDI file thus does not contain any music, but instructions about music events and objects. The device interprets the commands in the MIDI file and reproduces the music-related events. A MIDI file can only be rendered as playable sound on a PC if there is an onboard synthesizer -- or at least a MIDI connected synthesizer to the PC. MIDI files can be embedded in HTML files. MIDI files take the extension .mid or .midi.
