MIDI Support
The Musical Instrument Digital Interface (MIDI) enables consumers to use multimedia computers and
electronic musical instruments to create, enjoy, and learn about music.
electronic musical instruments to create, enjoy, and learn about music.
The MIDI protocol is a music description language in which every word describes an action of musical
performance. Each action is stored as a binary word, and when combined, stored as MIDI files. These
files can then be replayed by any electronic device that can read the MIDI file and recreate the
performance using its available sound system.
