FEATURES  
Your Optimus MD-1150 Electronic Key-  
board is a state-of-the-art keyboard with  
many exciting features. You can set the  
keyboard to sound like 100 different mu-  
sical instruments or sound effects. To  
accompany your music, the keyboard  
has 100 rhythms, as well as auto ac-  
companiments and percussion sounds.  
Backlit Liquid Crystal Display —  
shows the notes and chords as you play  
them, along with the current tone,  
rhythm, and tempo. The built-in back-  
light makes it easy to read the display  
even in darkness.  
16-Note Polyphonic Sound — lets you  
play and hear up to 16 notes at the  
same time so you can play or create al-  
most any type of music.  
Your keyboard also includes a MIDI  
(Musical Instrument Digital Interface)  
feature, which lets you connect it to oth-  
er MIDI-equipped musical instruments  
or devices, even your personal comput-  
er.  
100 Tones — you can set your key-  
board to sound like anything from a  
harpsichord to a honky-tonk piano.  
This versatile keyboard can provide  
hours of fun and is ideal for anyone who  
wants to make music, from the beginner  
to the experienced musician.  
100 Prerecorded Tunes — let you hear  
a sample of what you and the keyboard  
can do. You can play the tunes either  
one at a time or consecutively, and you  
can turn off the melody or accompani-  
ment portion so you can play along with  
the tunes.  
Note: The MD-1150 conforms to most,  
but not all, General MIDI specifications.  
Because of this, you might experience  
some incompatibility when using the  
MD-1150 with another General MIDI de-  
vice. For more information, see “Using  
MIDI” on Page 25.  
100 Auto-Rhythms — give you a  
steady beat for many styles of music,  
from rhumba to slow rock.  
Transpose Function — lets you in-  
stantly change the key of the music,  
even while you are playing.  
Your keyboard’s features include:  
61 Full-Size Keys with Touch Re-  
sponse — the keyboard’s volume var-  
ies in response to the force of your  
touch, just like an acoustic piano or or-  
gan, so you can add emotion to your  
music.  
Headphones/Output Jack — lets you  
connect headphones so you can play  
without disturbing others, or an external  
amplifier so you can play for a crowd.  
Sustain Jack — lets you connect a sus-  
tain pedal (not supplied) to the MD-1150  
so you can sustain your keyboard’s  
sound.

42-4039.fm Page 4 Friday, March 3, 2000 8:55 AM  
Tempo Control — lets you speed up or  
slow down the tempo of any selected  
music pattern.  
• This Owner’s Manual explains how  
to use this electronic keyboard. It  
does not teach music.  
Tune Control — lets you adjust the  
pitch of your keyboard so you can play  
in tune with other instruments.  
Fill-In Rhythm — lets you insert a short  
variation into any auto-rhythm.  
Auto Accompaniment — lets you auto-  
matically play a preset harmonic pattern  
to match the selected auto-rhythm.  
Chord Book — lets you easily see  
which keys to press and which fingers to  
use to form a chord, as well as easily  
learn the chord’s name.  
Two Built-In Speakers — provide ex-  
cellent sound to help make your music  
come alive.  
Power Options — let you power the  
keyboard from internal batteries (not  
supplied) or standard AC power (with an  
optional adapter) so you can make mu-  
sic almost anywhere.  
Notes:  
• If the keyboard is left in one place  
for a very long time, its feet could  
mar your furniture’s finish. We rec-  
ommend you place the feet on felt  
cloth pads to protect your furniture  
or use an optional keyboard stand,  
available at your local RadioShack  
store.

PREPARATION  
Note: To connect a MIDI device, see  
“Making the MIDI Connections” on  
Page 25. To connect a sustain pedal,  
• If you do not plan to use the MD-  
1150 with batteries for a week or  
more, or if you will be using only AC  
power, remove the batteries.  
see “Using  
Page 24.  
a
Sustain Pedal” on  
• Do not mix old and new batteries,  
different types of batteries (stan-  
dard, alkaline, or rechargeable), or  
rechargeable batteries of different  
capacities.  
CONNECTING POWER  
You can power your MD-1150 from ei-  
ther:  
• internal batteries (see “Using Batter-  
ies”)  
1. Press the tabs on the battery com-  
partment cover, then pull up to  
remove the cover.  
• standard AC power using an  
optional AC adapter (see “Using AC  
Power” on Page 8)  
2. Put the batteries in the compartment  
as indicated by the polarity symbols  
(+ and –) marked beside the com-  
partment.  
Notes:  
• Connecting an AC adapter automat-  
ically disconnects internal batteries.  
3. Replace the cover.  
• Always disconnect the adapter  
when you finish using the MD-1150.  
If the MD-1150 sounds weak or does not  
work properly, replace all six batteries.  
Using Batteries  
Warning: Dispose of old batteries  
promptly and properly. Do not burn or  
bury them.  
Your MD-1150 can use six D batteries  
(not supplied) for power. For the best  
performance and longest life, we recom-  
mend RadioShack alkaline batteries.  
Caution: Always remove old or weak  
batteries; batteries can leak chemicals  
that can destroy electronic parts.  
Cautions:  
• Use only fresh batteries of the  
required size and recommended  
type.

Using AC Power  
CONNECTING  
HEADPHONES  
You can power your MD-1150 from  
standard AC power using a 9-volt AC  
adapter (not supplied) and a Size M  
Adaptaplug®.  
To listen to your MD-1150 without dis-  
turbing others, you can connect a pair of  
1
4
/ -inch (6.35-mm) plug stereo head-  
phones (not supplied). Your local Ra-  
dioShack store sells a wide selection of  
headphones.  
Cautions:  
You must use an AC  
adapter that supplies 9  
!
volts and delivers at least  
800 milliamps. Its center tip must be  
set to negative, and its plug must  
correctly fit the MD-1150’s DC 9V  
jack. Using an adapter that does not  
meet these specifications could  
damage the MD-1150 or the  
adapter.  
To connect a pair of headphones, insert  
the headphones’ plug into the PHONES/  
OUTPUT jack on the back of the key-  
board.  
• Always press POWER to turn off the  
keyboard before you connect or dis-  
connect the adapter.  
• Always plug the AC adapter into the  
MD-1150 before you plug it into the  
AC outlet. Always unplug the AC  
adapter from the AC outlet before  
you unplug it from the MD-1150.  
Note: Connecting headphones discon-  
nects the MD-1150’s built-in speakers.  
Listening Safely  
Follow these steps to power your MD-  
1150 from AC power.  
To protect your hearing, follow these  
guidelines when you use headphones.  
1. Insert the adapter’s barrel plug into  
the DC 9V jack on the back of the  
MD-1150.  
• Set the volume to the lowest setting  
before you begin listening. After you  
begin listening, adjust the volume to  
a comfortable level.  
2. Plug the adapter into a standard AC  
outlet.  
• Do not listen at extremely high vol-  
ume levels. Extended high-volume  
listening can lead to permanent  
hearing loss.

42-4039.fm Page 9 Friday, March 3, 2000 8:55 AM  
• Once you set the volume, do not  
increase it. Over time, your ears  
adapt to the volume level, so a vol-  
ume level that does not cause dis-  
comfort might still damage your  
hearing.  
CONNECTING AN  
EXTERNAL AMPLIFIER  
To amplify your MD-1150’s sound, you  
can connect it to an external amplifier  
(not supplied) using an audio cable (not  
1
4
supplied) with a / -inch (6.35-mm) plug.  
To connect an external amplifier to your  
1
4
keyboard, insert the cable’s / -inch  
(6.35-mm) plug into the PHONES/OUT-  
PUT jack on the back of the keyboard,  
and connect the cable’s other end to the  
amplifier’s input jack(s) (such as AUX IN  
or TAPE IN).  
Your local RadioShack store sells a full  
line of amplifiers, speakers, and connec-  
tion cables.  
USING THE MUSIC STAND  
To easily view sheet music while playing  
your keyboard, insert the supplied music  
stand into the slot on the top back panel.

Notes:  
2. To play a different tone, choose a  
preset tone from the 100 TONES list  
and enter its two-digit number on  
the keypad. As you press the keys,  
the selected digits appear.  
• The keyboard has 16-note (maxi-  
mum) 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.  
Or, you can use + or to move to  
the next higher or lower numbered  
tone.  
Notes:  
• Most tones on this keyboard have  
been recorded and processed using  
a technique called digital sampling.  
To ensure a high level of tonal qual-  
ity, samples are taken in the low,  
mid, and high ranges and are then  
combined to sound amazingly 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 unavoid-  
able result of multiple sampling and  
is not a malfunction.  
• Precede a single-digit number  
with a 0. For example, to select  
ELEC PIANO 1 (No. 04), press 0  
4.  
• If you enter an incorrect first digit,  
press TONE to clear your entry,  
then enter the correct digit.  
3. Play the keyboard to hear the  
selected tone and adjust MAIN VOL-  
UME to the desired level.  
4. To select a different tone, repeat  
Steps 1 and 2.  
• Some sound effect tones, such as  
PERCUSSION (No. 99), do not fol-  
low the musical scale when played,  
but change effect as you play them  
in different octaves on the keyboard.  
Keyboard Split Tones  
The preset tones numbered 90 through  
96 on your keyboard let you automati-  
cally play two different musical instru-  
ments or sound effects independently  
on opposite sides of the keyboard.

(semitone).  
CHANGING KEYS  
The keyboard automatically selects the  
key of middle C each time you turn it on.  
As you raise the key, 1 is C#, 2 is D,  
and so on. As you lower the key, –1  
is B, –2 is A#, –3 is A, and so on.  
For added flexibility as you play, the  
keyboard lets you change (transpose)  
the musical key in which it plays.  
Notes:  
• You can also use the number key-  
pad to quickly raise the key. Simply  
press the semitone change value (1  
to 5).  
Note: You cannot change the key while  
a prerecorded tune is selected or play-  
ing.  
• The keyboard automatically resets  
the key to the default value of 0  
(middle C) each time you play a pre-  
recorded tune.  
1. Repeatedly press TRANSPOSE/  
TUNE/MIDI until Trans and the cur-  
rent key setting appear.  
TRANSPOSE/TUNE/MIDI  
• Each preset tone plays within a  
specified range. If a key change  
causes a note to exceed its range,  
the same note sounds in the nearest  
octave.  
• When you select preset tones 90  
through 96 after changing the key,  
the keyboard split point changes  
accordingly (see “Keyboard Split  
Tones” on Page 14).  
Note: The number on the display is  
the number of “semitones” to which  
the keyboard is set, compared to its  
default key. A semitone is a mea-  
surement that represents the acous-  
tical interval between the tones of  
any two keys on the keyboard.  
• Changing the key does not affect  
the PERCUSSION (No. 99) preset  
tone.  
For  
example,  
the  
difference  
TUNING THE KEYBOARD  
between C and C# or B and B# is  
one semitone. You can transpose  
the key down 6 semitones (to an F#)  
and up 5 semitones (to an F) — a  
full octave.  
Although your keyboard never goes out  
of tune, it does let you adjust its pitch to  
match other instruments or musical re-  
cordings.

TUNE/MIDI until the display shows  
Tune and the current pitch setting.  
Note: The number on the display is  
the number of “cents” to which the  
keyboard is currently tuned, com-  
pared to its default pitch. A cent is  
the measurement that represents  
the acoustical interval between two

• The touch response setting does not  
affect auto accompaniment or  
received MIDI data.  
• The MIDI data sent out from the  
MD-1150 is affected by the touch  
response setting.  
Notes:  
• You can use the number keypad to  
raise the pitch by entering the cent  
change value.  
USING A SUSTAIN PEDAL  
• The keyboard automatically resets  
the tuning pitch to the default value  
of 00 (cents) each time you turn off  
the keyboard or play the pre-  
recorded tunes.  
For added flexibility and control as you  
make music, you can connect an option-  
al sustain pedal (not supplied), available  
through your local RadioShack store. A  
sustain pedal lets you sustain the key-  
board’s sound.  
USING TOUCH RESPONSE  
To connect a sustain pedal to your MD-  
1150, insert the plug on the pedal’s cord  
into the SUSTAIN jack on the back of the

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.  
Your MD-1150 has MIDI OUT and MIDI IN  
terminals.  
MIDI OUT  
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.  
MIDI IN  
ABOUT MIDI  
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.  
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.  
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.

42-4039.fm Page 26 Friday, March 3, 2000 8:55 AM  
Cautions:  
• For detailed specifications of the  
MIDI function, see the “MIDI Imple-  
mentation Chart” on Page 34.  
• Always turn off power to your MD-  
1150 and the other MIDI device  
before you connect or disconnect  
MIDI cables.  
Note On/Off — specifies which keys are  
pressed (Note On) or released (Note  
Off). Also includes how loud a note is  
played as a value from 0 to 127.  
• As you make the cable connections,  
be sure to align the MIDI cable pins  
with the matching holes on your  
keyboard’s MIDI OUT and MIDI IN ter-  
minals. If you have trouble plugging  
in the cable, do not force it! You  
might damage the plug or the instru-  
ment.  
Notes:  
• The pitch of a note depends on the  
tone that is being used, as shown in  
the “Note Table” on Page 33.  
• If the keyboard receives a “request”  
to play notes outside of its range  
(higher or lower), it automatically  
selects the same note in the nearest  
octave.  
To send MIDI data from your keyboard,  
use a MIDI cable to connect the MD-  
1150’s MIDI OUT terminal to the other  
device’s MIDI IN terminal.  
To receive MIDI data on your keyboard,  
use a MIDI cable to connect the MD-  
1150’s MIDI IN terminal to the other de-  
vice’s MIDI OUT terminal.  
Program Change — specifies the tone.  
The keyboard sends program change  
data in the range of 0 to 99, correspond-  
ing to tone numbers. It receives data  
within the same range if GM tone map-  
ping 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 tone  
that the keyboard has.  
Note: You do not need to make both  
connections if you are only either send-  
ing or receiving.  
MIDI DATA  
Pitch Bend — supplies pitch bend infor-  
mation. The keyboard’s pitch changes  
as it receives a Pitch Bend message  
through the MIDI IN terminal.  
Your MD-1150 can send and receive  
several different types of MIDI data. The  
MD-1150’s tones, rhythms, and other  
types of MIDI data are sent automatical-  
ly as you play.  
Control Change — adds effects such  
as vibrato and volume changes applied  
during keyboard play. The message in-  
cludes a control number (the effect type)  
and a control value (the on/off and depth  
of the effect).  
Notes:  
• The MD-1150’s prerecorded tunes  
cannot be sent as MIDI data.

NOTES ABOUT THE MIDI  
IMPLEMENTATION  
CHART  
The “MIDI Implementation Chart” on  
Page 34 illustrates the details of the key-  
board’s MIDI function. An O in the chart  
means that the keyboard has this fea-  
ture; an X means it does not have this  
feature. The following notes explain  
what the keyboard can do.  
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 controllers, each having  
its own number. For the details of each  
parameter, see “MIDI Data” on Page 26.  
Basic Channel — MIDI uses up to 16  
channels to exchange data. As in a TV  
broadcast, different channels send dif-  
ferent data. The keyboard can send data  
in any of 16 channels, but receives data  
only on channels 1 through 4 or 10.  
Program Change  
This feature  
changes the preset sounds. Each sound  
number corresponds to a program num-  
ber between 0 and 127. For more infor-  
mation, see “MIDI Data” on Page 26.  
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.  
Note Number — This number repre-  
sents each key of the keyboard. The  
lowest number (0) is five octaves below  
middle C. Since the keyboard’s lowest  
note is two octaves below middle C and  
the highest is three octaves above mid-  
dle C, your keyboard can send note  
numbers between 36 and 96 and re-  
ceive note numbers from 0 through 127.  
The keyboard automatically assigns 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

CARE AND MAINTENANCE  
Your Optimus MD-1150 Electronic Keyboard is an example of superior design and  
craftsmanship. The following suggestions will help you care for your keyboard so  
you can enjoy it for years.  
Keep the keyboard dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Use and store the keyboard only in normal temperature environments.  
Temperature extremes can shorten the life of electronic devices, dam-  
age batteries, and distort or melt plastic parts.  
Keep the keyboard away from dust and dirt, which can cause prema-  
ture wear of parts.  
Handle the keyboard gently and carefully. Dropping it can damage cir-  
cuit boards and cases and can cause the keyboard to work improperly.  
Use only fresh batteries of the required size and recommended type.  
Batteries can leak chemicals that damage your keyboard’s electronic  
parts.  
Wipe the keyboard with a damp cloth occasionally to keep it looking  
new. Do not use harsh chemicals, cleaning solvents, or strong deter-  
gents to clean the keyboard.  
Modifying or tampering with the keyboard’s internal components can cause a mal-  
function and might invalidate its warranty. If your keyboard is not performing as it  
should, take it to your local RadioShack store for assistance.

Limited One-Year Warranty  
This product is warranted by RadioShack against manufacturing defects in material and workman-  
ship under normal use for one (1) year from the date of purchase from RadioShack company-owned  
stores and authorized RadioShack franchisees and dealers. EXCEPT AS PROVIDED HEREIN, Ra-  
dioShack MAKES NO EXPRESS WARRANTIES AND ANY IMPLIED WARRANTIES, INCLUDING  
THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED  
IN DURATION TO THE DURATION OF THE WRITTEN LIMITED WARRANTIES CONTAINED  
HEREIN. EXCEPT AS PROVIDED HEREIN, RadioShack SHALL HAVE NO LIABILITY OR RE-  
SPONSIBILITY TO CUSTOMER OR ANY OTHER PERSON OR ENTITY WITH RESPECT TO ANY  
LIABILITY, LOSS OR DAMAGE CAUSED DIRECTLY OR INDIRECTLY BY USE OR PERFOR-  
MANCE OF THE PRODUCT OR ARISING OUT OF ANY BREACH OF THIS WARRANTY, IN-  
CLUDING, BUT NOT LIMITED TO, ANY DAMAGES RESULTING FROM INCONVENIENCE, LOSS  
OF TIME, DATA, PROPERTY, REVENUE, OR PROFIT OR ANY INDIRECT, SPECIAL, INCIDEN-  
TAL, OR CONSEQUENTIAL DAMAGES, EVEN IF RadioShack HAS BEEN ADVISED OF THE  
POSSIBILITY OF SUCH DAMAGES.  
Some states do not allow the limitations on how long an implied warranty lasts or the exclusion of in-  
cidental or consequential damages, so the above limitations or exclusions may not apply to you.  
In the event of a product defect during the warranty period, take the product and the RadioShack  
sales receipt as proof of purchase date to any RadioShack store. RadioShack will, at its option, un-  
less otherwise provided by law: (a) correct the defect by product repair without charge for parts and  
labor; (b) replace the product with one of the same or similar design; or (c) refund the purchase  
price. All replaced parts and products, and products on which a refund is made, become the prop-  
erty of RadioShack. New or reconditioned parts and products may be used in the performance of  
warranty service. Repaired or replaced parts and products are warranted for the remainder of the  
original warranty period. You will be charged for repair or replacement of the product made after the  
expiration of the warranty period.  
This warranty does not cover: (a) damage or failure caused by or attributable to acts of God, abuse,  
accident, misuse, improper or abnormal usage, failure to follow instructions, improper installation or  
maintenance, alteration, lightning or other incidence of excess voltage or current; (b) any repairs  
other than those provided by a RadioShack Authorized Service Facility; (c) consumables such as  
fuses or batteries; (d) cosmetic damage; (e) transportation, shipping or insurance costs; or (f) costs  
of product removal, installation, set-up service adjustment or reinstallation.  
This warranty gives you specific legal rights, and you may also have other rights which vary from  
state to state.
