100 Prerecorded Tunes — let you hear
a sample of what you and the k eyboard
can do. You can play the tunes either
one at a time or c onsecutively, and you

steady beat for many styles of music,
from rhumba to slow rock.
Transpose Function — lets you instantly change the key of the music,
even while you are playing.

CONNECTING POWER
You can power your MD-1150 from either:
• internal batteries (see “Using Batteries”)
• standard AC power using an
optional AC adapter (see “Using AC
Power” on Page 8)
Notes:
• Connecting an AC adapt er automatically disconnects internal batteries.
• Always disconnect the adapter
when you finish using the MD-1150.
Using Batteries
Your MD-1150 can use six D batteries
(not supplied) for power. For the best
performance and longest life, we rec om mend RadioShack alkaline batteries.
Cautions:
• If you do not plan to use the MD1150 with batteries for a week or
more, or if you will be usin g only A C
power, remove the batteries.
• Do not mix old and new batteries,
different types of batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
1. Press the tabs on the batte ry compartment cover, then pull up to
remove the cover.
2. Put the batteries in the compartment
as indicated by the polar ity symbols
(+ and –) marked beside the compartment.
3. Replace the cover.
If the MD-1150 sounds weak or does not
work properly, replace all six batteries.
Warning: Dispose of old batteries
promptly and properly. Do not burn or
bury them.
Caution: Always remove old or weak
batteries; batteries can leak chemicals
that can destroy electronic parts.
• Use only fresh batteries of the
required size and recommended
type.

meet these specifications could
damage the MD-1150 or the
adapter.
• Always press
keyboard before you c onnect or disconnect the adapter.
• Always plug the AC a dapter i nto the
MD-1150 before you plug it into the
AC outlet. Always unplug the AC

Notes:
• The keyboard has 16-note (maximum) polyphonic sound. This
means that you can play up to 16
different notes at the same time with
most of the keyboard’s preset tones.
Some of the keyboard’s preset
tones, however, are capable of only
8-note polyphony.
• Most tones on this keyboard have
been recorded and proc essed u sing
a technique called digital sampling.
To ensure a high lev el of tonal quality, samples are taken in the low,
mid, and high rang es and are then
combined to soun d amazingl y close
to the originals. You might notice
very slight differences in volume or
sound quality for some tones when
you play them at different positions
on the keyboard. This is an unavoidable result of multiple sa mpling and
is not a malfunction.

42-4039.fm Page 25 Friday, March 3, 2000 8:55 AM
USING MIDI
Your MD-1150 includ es a feature call ed
MIDI
(Musical Instrument Digital Interface). MIDI is the universal standard fo r
sending and receiving performance data
between all types of electronic musical
instruments, reg ardless of the m anufacturer.
Using MIDI, you can play music on you r
MD-1150 and another instr ument at the
same time while pressing the keys on
only one, record your music to a sequencer, 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 purpose.
MIDI OUT sends MIDI data to (“talks to”)
the other MIDI instrument(s).
MIDI IN receives (“listens to”) M IDI data
sent by the other MIDI instrument(s).
Your MD-1150 has
terminals.
MIDI OUT
MIDI IN
The cable that connects MIDI devices
does not actually carry sound between
them, like a spe aker wire carries soun d
from a receiver to a speaker. Instead,
MIDI-equipped devices communicate
with each other using digital codes (instructions). O ne MIDI d evice sends dig ital 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.
MIDI OUT
and
MIDI IN
MIDI THRU lets you connect (“network”)
additional MIDI instruments, and sends
along to other MIDI devices a copy of al l
data it receives through its MIDI IN terminal.
MAKING THE MIDI
CONNECTIONS
To connect your MD-1150 to another
MIDI-equipped device, you must use a
MIDI cable, available at your local RadioShack store.
25
Page 26
42-4039.fm Page 26 Friday, March 3, 2000 8:55 AM
Cautions:
• Always turn off power to your MD-
1150 and the other MIDI device
before you connect or disconnect
MIDI cables.
• As you make the cabl e co nne cti ons,
be sure to align the MIDI cable pins
with the matching holes on your
keyboard’s
MIDI OUT
and
MIDI IN
terminals. If you h ave trouble plu gging
in the cable, do not force it! You
might damage the plug or the instrument.
To send MIDI data fr om your keyboar d,
use a MIDI cable to connect the MD1150’s
MIDI OUT
terminal to the other
device’s MIDI IN terminal.
To receive MIDI data on y our keybo ard,
use a MIDI cable to connect the MD1150’s
MIDI IN
terminal to the other de-
vice’s MIDI OUT terminal.
Note: You do not need to make both
connections if you are only e ither sending or receiving.
MIDI DATA
Your MD-1150 can send and receive
several different ty pe s o f MIDI data. The
MD-1150’s tones, rhythms, and other
types of MIDI data are sent auto matic ally as you play.
Notes:
• The MD-1150’s prerecorded tunes
cannot be sent as MIDI data.
• For detailed specifications of the
MIDI function, see the “MIDI Implementation Chart” on Page 34.
Note On/Off — specifie s w hic h k e ys a re
pressed (Note On) or released (Note
Off). Also includes how loud a note is
played as a value from 0 to 127.
Notes:
• The pitch of a note depends on the
tone that is being used, as show n in
the “Note Table” on Page 33.
• If the keyboard rec eives a “request”
to play notes outside of its range
(higher or lower), it automatically
selects the same note in the nearest
octave.
Program Change — specifies the tone.
The keyboard sends program change
data in the range of 0 to 99, corresponding to tone numbers. It receives data
within the same range if GM tone mapping is set to N, or in the range of 0 to
127 if GM tone mapping is set to G. In
the latter case, tones in the range of 100
to 127 are translated to the closest ton e
that the keyboard has.
Pitch Bend — supplies pitch bend information. The keyboard’s pitch changes
as it receives a Pitch Bend message
through the MIDI IN terminal.
Control Change — adds effects such
as vibrato and volume chan ges applied
during keyboard p lay. The message includes a control number (the effect type)
and a control value (the on/off and depth
of the effect).

TonMap=N
appears.
2. Within 5 seconds, press
–
or + to
select the setting you want.
N: Normal Tone Map. This setting
allows receipt of 0 to 99 program
changes. Each program change
corresponds to one of the keyboard’s prerecorded tones.
G: General MIDI Tone Map. This
setting allows rec eipt of all 0 to 127
program changes. Any data over
100 are translated to the closest
tone the MD-1150 has. See “Note
Table” on Page 33 for details.
Select G when you listen to Gener al
MIDI data from an external device.
Keyboard Channel — sets the channel
for sending MIDI data to an ex ternal device (Default: 01). The MD-1150 receives MIDI data on channe ls 1 thr ough
4 and 10 only. The data received on other channels are ignored. For transmission of MIDI data, you can use any of 16
channels.
1. Repeatedly press

NOTES ABOUT THE MIDI
IMPLEMENTATION
CHART
The “MIDI Implementation Chart” on
Page 34 illustrates the details of the keyboard’s MIDI function . An O in the c hart
means that the keyboard has this feature; an X means it d oes not have this
feature. The following notes explain
what the keyboard can do.
Basic Channel — MIDI uses up to 16
channels to exchange da ta. As in a TV
broadcast, different channels send different data. The keyboard can send data
in any of 16 channels, but r eceives d ata
only on channels 1 through 4 or 10.
Mode — The chart shows that Mode 3 is
OMNI OFF, POLY. This means the key board sends and receives polyphonic
data on only one channel at a time.
the loudest. A zero (0) mea ns the key is
released. Your key board can send and
receive all volume lev els from 0 through
127.
9n — This means that the Note On mes-
sage is 9 hexadecimal, and n is the
channel number.
Pitch Bender — The keyboard receives
(but cannot send) pitch bending signals.
Control Change — This feature sends
data on various co ntroller s, each having
its own number. Fo r the details of eac h
parameter, see “MIDI Data” on Page 26.
Program Change — This feature
changes the preset sounds. Each sound
number corresponds to a prog ram number between 0 and 127. For more information, see “MIDI Data” on Page 26.
Note Number — This number repre-
sents each key of the keyboard. The
lowest number (0) is five oc taves below
middle C. Since the keyboard’s lowest
note is two octave s below middle C a nd
the highest is t hree octaves above m iddle C, your keyboard can send note
numbers between 36 and 96 and receive note numbers fro m 0 through 1 27.
The keyboard automatically assig n s any
key outside its range to a key within its
key range.
Velocity — This number shows how
fast the key was pressed, or how loud
the note should sound. Pianissimo (1) is
the lowest velocity, Fortissimo (127) is
