What is MIDI?
MIDI (Musical Instrument Digital Interface) is the international standard for digital communication of elec-
tronic musical instrument data. This means that any equipment which has a MIDI terminal—such as elec-
tronic musical instruments and personal computers—can easily exchange digital data with other MIDI
equipment without resorting to complicated conversions or connections.
MIDI terminals
(On the rear panel) IN:
The terminal by which this instrument receives
data from other equipment.
OUT:
The terminal that transmits data from this
instrument to other equipment.
• For these connections, use a commercially available
MIDI cable.

MIDI channels
Many different kinds of performance data are
sent using just one MIDI cable. This is possible
because MIDI signals are sent and received
through 16 different “basic channels” (numbered
1 to 16). In order for the exchange of data to take
place, the channels on the transmission side
must match the channels on the receiving side.
This characteristic also makes it possible to link
multiple sound generators and to control each by
matching specific channels.
