MIDI or Musical Instrument Digital Interface is a connectivity standard used by musicians to connect musical instruments and computer systems. By using MIDI, musicians are able to produce and revise digital music tracks. The MIDI system is able to record the notes played, the length of these notes, the volume alterations, the tempo, the instrument used to play, and other parameters called control changes. Since MIDI records each of the notes digitally, editing of tracks became easier and more accurate. The control parameters can be changed by a single click.

The DLS file extension is also associated with the Norton Disklock Program.
