USING MIDI

Your MD-1150 includes a feature called
MIDI (Musical Instrument Digital Inter-
face). MIDI is the universal standard for
sending and receiving performance data
between all types of electronic musical
instruments, regardless of the manufac-
turer.
Using MIDI, you can play music on your
MD-1150 and another instrument at the
same time while pressing the keys on
only one, record your music to a se-
quencer, acquire a wider selection of
preset tones from a sound module, 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 MD-1150 has
MIDI OUT
terminals.
MIDI OUT
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.
MAKING THE MIDI
CONNECTIONS
To connect your MD-1150 to another
MIDI-equipped device, you must use a
MIDI cable, available at your local Ra-
dioShack store.
