What is MIDI?

MIDI (Musical Instrument Digital Interface) is a
world-standard interface for communication
between electronic musical instruments and
music devices. When MIDI-equipped instru-
ments are connected via a MIDI cable, it
becomes possible to transfer performance and
setting data between them for significantly
enhanced performance and production potential.
