Acronym: Musical Instrument Digital Interface

Audio standard for device connectivity. MIDI allows for multiple types of audio equipment, old and new, to easily and quickly interface with one another. For instance, this interface allows one to assign sounds to a keyboard.

Most MIDI devices are connected via serial cable. However, an increasing number of devices are connecting through USB and allow more features but no successor to MIDI has yet been created, despite being a very old technology.

Sequencer software is needed to record and edit MIDI data. Editing a MIDI file allows for precise control down to the volume of each note. Rather than representing sounds, MIDI plays back musical instruments. It is therefore no good for the spoken word.
