USING MIDI

Your Concertmate 980 includes a fea-
ture called MIDI (Musical Instrument
Digital Interface). MIDI is the universal
standard for sending and receiving per-
formance data between all types of elec-
tronic musical instruments, regardless of
the manufacturer.
Using MIDI, you can play music on your
Concertmate 980 and another instru-
ment at the same time while pressing
the keys on only one, record your music
to a sequencer, acquire a wider selec-
tion of preset tones from a sound mod-
ule, and much more.

ABOUT MIDI

Every MIDI-equipped instrument has
MIDI OUT and IN terminals, and some
also have a MIDI THRU terminal. Each
of these terminals serves a different pur-
pose.
MIDI OUT sends MIDI data to ("talks
to") the other MIDI instrument(s).
MIDI IN receives ("listens to") MIDI data
sent by the other MIDI instrument(s).
MIDI THRU lets you connect ("network")
additional MIDI instruments, and sends
along to other MIDI devices a copy of all
data it receives through its MIDI IN ter-
minal.
Your Concertmate 980 has
and terminals.
MIDI IN
The cable that connects MIDI devices
does not actually carry sound between
them, like a speaker wire carries sound
from a receiver to a speaker. Instead,
MIDI-equipped devices communicate
with each other using digital codes (in-
structions). One MIDI device sends digi-
tal instructions representing exactly
what is being played on it. The other
MIDI device receives and translates
those instructions, then produces (or
records) the sound exactly as it was
played on the first device.
Note: Connecting your keyboard to an-
other MIDI device requires a MIDI cable
(not supplied). See "Making the MIDI
Connections."
MAKING THE MIDI
CONNECTIONS
To connect your Concertmate 980 to an-
other MIDI-equipped device, you must
use a MIDI cable, such as RSU Cat. No.
42-2468 or 26-0379.
Cautions:
• Always turn off power to your Con-
certmate 980 and the other MIDI de-
vice before you connect or dis-
connect MIDI cables.
• As you make the cable connections,
be sure to align the MIDI cable pins
with the matching holes on your
MIDI OUT
keyboard's
minals. If you have trouble plugging
in the cable, do not force it! You
might damage the plug or the instru-
ment.
