What is MIDI?
MIDI (Musical Instrument Digital Interface) is the international standard for digital communication of electronic musical instrument
data. This means that any equipment which has a MIDI terminal—such as electronic musical instruments and personal comput-
ers—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.
THRU:
The terminal that transfers data from the IN terminal
directly.
• For these connections, use a commercially available MIDI
cable.
Connection examples
To generate sound from a connected instrument by playing this instrument
To generate sound from this instrument by operating a connected instrument
To connect with a MIDI sequencer
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” (num-
bered 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.
