ment that offers you a vast array of

sounds. You can choose from 200 differ-

ent musical instruments or sound effects

and 100 rhythms, as well as automatic

24-Note Polyphonic Sound — lets you

play and hear up to 24 notes at the

same time, so you can play or create al-

most any type of music.

The MD-1200 also includes a MIDI fea-

ture (Musical Instrument Digital Inter-

face), which lets you connect it to other

MIDI-equipped musical instruments or

devices — even your personal comput-

er! 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.

Pitch Bender Wheel — lets you bend a

note by altering its pitch to create realis-

tic effects for reed instrument or guitar

tones.

200 Tones — let you set your MD-1200

to sound like anything from a harpsi-

chord to a honky-tonk piano. You can

even create your own tones with the

custom tone synthesizer feature.

Note: The MD-1200 conforms to most,

but not all, General MIDI specifications.

Therefore, you might experience some

incompatibility when using the MD-1200

with another General MIDI device. For

connect headphones so you can play

without disturbing others, or an external

amplifier so you can play for a crowd

(neither supplied).

Your MD-1200’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.

Assignable Jack — lets you connect a

sustain pedal (not supplied) to the MD-

1200 so you can sustain or soften your

keyboard’s sound, or start/stop an auto-

rhythm.

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.

100 Free Sessions — let you set the

MD-1200 to automatically play an ac-

companiment consisting of a prerecord-

ed chord progression with a matching

PREPARATION

Note: To connect a MIDI device, see

“Making the MIDI Connections” on

Page 41. To connect a sustain pedal,

Cautions:

• Use only fresh batteries of the

required size and recommended

type.

see “Using

Page 31.

Sustain Pedal” on

• If you do not plan to use the MD-

1200 with batteries for a week or

more, or if you will be using only AC

power, remove the batteries.

CONNECTING POWER

You can power your MD-1200 from ei-

ther:

• Do not mix old and new batteries,

different types of batteries (stan-

dard, alkaline, or rechargeable), or

rechargeable batteries of different

capacities.

• internal batteries (see “Using Batter-

ies”)

• standard AC power using an

optional AC adapter (see “Using AC

Power” on Page 8)

Notes:

• Connecting an AC adapter automat-

ically disconnects internal batteries.

• Always disconnect the adapter

when you finish using the MD-1200.

1. Press the tabs on the battery com-

partment cover, then pull up to

remove the cover.

• Disconnecting the keyboard’s power

clears the control settings, memory

contents, and user tones (see

“Using the Custom Tone Synthe-

sizer” on Page 24 and “Using the

Memory” on Page 32).

2. Put the batteries in the compartment

as indicated by the polarity symbols

(+ and –) marked beside the com-

partment.

3. Replace the cover.

Using Batteries

If the MD-1200 sounds weak or does not

work properly, replace all six batteries.

Your MD-1200 can use six D batteries

(not supplied) for power. For the best

performance and longest life, we recom-

mend RadioShack alkaline 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.

42-4041.fm Page 8 Tuesday, August 3, 1999 6:56 AM

Using AC Power

CONNECTING

HEADPHONES

You can power your MD-1200 from

standard AC power using a 9-volt AC

adapter (not supplied) and a Size M

Adaptaplug.

To listen to your MD-1200 without dis-

turbing others, you can connect a pair of

/ -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 a Class 2

power source that supplies

9 volts DC and delivers at

least 800 mA. Its center tip must be

set to negative and its plug must fit

the MD-1200's DC 9V jack. Using an

adapter that does not meet these

specifications could damage the

MD-1200 or the adapter.

To connect a pair of headphones, insert

the headphones’ / -inch (6.35-mm) plug

into the PHONES/OUTPUT jack on the

back of the keyboard.

• Always press POWER to turn off the

keyboard before you connect or dis-

connect the adapter.

• Always plug the AC adapter into the

MD-1200 before you plug it into the

AC outlet. Always unplug the AC

adapter from the AC outlet before

you unplug it from the MD-1200.

Note: Connecting headphones discon-

nects the MD-1200’s built-in speakers.

Listening Safely

Follow these steps to power your MD-

1200 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-1200.

• 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.

42-4041.fm Page 9 Tuesday, August 3, 1999 6:56 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-1200’s sound, you

can connect it to an external amplifier

(not supplied) using an audio cable (not

supplied) with a / -inch (6.35-mm) plug.

To connect an external amplifier to your

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.

tones, however, are capable of only

12-note polyphony.

• 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 then com-

bined. You might notice very slight

differences in volume or sound qual-

ity for some tones when you play

them at different positions on the

keyboard. This is an unavoidable

result of multiple sampling and is

normal.

Note: The MD-1200 automatically

selects the tone GRAND PIANO

(No. 000) the first time you turn on

power.

Notes:

• The MD-1200 has 24-note (maxi-

mum) polyphonic sound. This

means that you can play up to 24

different notes at the same time with

most of the keyboard’s preset tones.

Using VARIATION

You can set the MD-1200 to play three

different types of auto accompaniment.

Each of the MD-1200’s 100 preset auto-

rhythms has a built-in variation (alter-

nate) to its normal beat pattern. The

variation differs slightly from the normal

rhythm, so it is almost like having two

rhythms in one!

can omit the finger positions shown in parentheses (on the keys).

• When producing an aug, 7-5, or dim7 chord, the lowest note you play determines

the root of the chord. Be sure that your fingering correctly defines the root you

want.

• The diagrams above show only one possible fingering position for each chord. It

is possible to play a chord using several different positions. For example, these

three fingering positions produce the same C chord.

• The preset tone you use as the

basis for a user tone is not changed.

Understanding 1DCO and

2DCO Tones

• The tone locations 168–199 are not

empty (before you store user tones

there). They initially contain dupli-

cate versions of tone numbers 128–

159. The user tone you store in any

of those locations replaces the exist-

ing tone. If you delete a user tone,

the keyboard automatically restores

the initial, duplicate tone there.

A Digital Controlled Oscillator (DCO)

controls the sound output of a digital sig-

nal. Some of the MD-1200’s built-in

tones are simple tones (1DCO), and

some are layered tones (2DCO). When

you select a 2DCO tone as the basis for

creating a user tone, you need to

change the parameters of both tones.

The parameters you can change are di-

vided into four groups. For the details of

each parameter, see “Creating and Stor-

Hints on Creating a User Tone

• Use a preset tone that is similar to

the one you are trying to create.

When you already have a general

idea of the tone you are trying to

create, it is a good idea to start with

a similar preset tone. If you want to

use a layered tone, start out with a

2DCO tone.

• Determine the most important

parameter. The PCM Set and Amp

Envelope Set parameters are the

major factors that determine the

overall tone characteristic. Start out

by setting these two parameters to

get the general sound you want, and

then set the other parameters to add

the finishing touches.

• Experiment with different settings.

There are no real rules about what a

tone should sound like. Let your

imagination run free and experiment

with different combinations. You

might be surprised at what you can

achieve!

Deleting a User Tone

To delete an existing user tone, follow

Steps 1–5 of “Creating and Storing a

User Tone” on Page 25. When SAVE ?

appears in Step 5, press

twice. The

display changes to Delete? Press

TONE to delete. The parameters of the

default tone for that number are re-

stored.

turn off during a session, turn the key-

board on while holding down TONE.

• Memory playback uses the pitch

with which the memorized tune was

recorded.

The next time you turn the MD-1200 off

then back on again, it automatically

turns off after about 6 minutes.

• Auto accompaniment uses the cur-

rently set pitch.

USING PITCH BEND

USING TOUCH RESPONSE

PITCH BEND lets you bend a note by al-

tering its pitch. It helps to create realistic

effects for saxophone, other reed instru-

ments, and guitar tones.

The MD-1200 has a touch response fea-

ture that lets you adjust the volume of

your music’s tone based on how hard

you strike the key(s), so you can add

emotion to your music.

Follow these steps to use PITCH BEND.

1. Select a tone.

To turn off this feature, press TOUCH

RESPONSE so its indicator disappears.

2. While holding down a keyboard key,

rotate and hold PITCH BEND. The

pitch of the tone slides smoothly up

or down.

To turn on touch response again, press

TOUCH RESPONSE so its indicator ap-

pears.

Notes:

PITCH BEND

• The touch response setting does not

affect auto accompaniment or

received MIDI data.

• The MIDI data sent out from the

MD-1200 is affected by the touch

response setting.

3. Release PITCH BEND to return to

the original pitch.

To connect a sustain pedal to your MD-

1200, insert the plug on the pedal’s cord

into ASSIGNABLE JACK on the back of

the keyboard.

Setting the Pitch Bend Range

You can adjust the bend range of pitch

controls from 1 to 12 semitones.

Note: The keyboard automatically se-

lects a bend range of 2 semitones the

first time you turn it on after connecting

power. Each time you turn it on after

that, it recalls the last selected bend

range.

You can adjust the MD-1200’s assign-

able jack to these settings when you use

a sustain pedal.

USING THE MEMORY

The MD-1200 lets you record up to two

separate songs in memory for later play-

back. You can use either of two meth-

ods to record a song — real-time

recording (you record as you play) or

step recording (you enter notes and

chords one-by-one).

• To start recording with synchro start,

press SYNCHRO/ENDING instead of

START/STOP in Step 5 of “Real-Time

Recording.” Recording starts when

you play a note or a chord on the

accompaniment keys.

• To record using an intro, ending, or

fill-in, use INTRO, SYNCHRO/END-

ING, NORMAL/FILL-IN, or VARIA-

TION/FILL-IN as you normally would.

You can record on each of the MD-

1200’s six tracks separately. Besides

notes, each track can have its own tone

number. Then, when you play back the

tracks together, it sounds like an entire

six-piece band. Also, you can use differ-

ent mixer settings for each track.

• To synchro start auto accompani-

ment with an intro pattern, press

SYNCHRO/ENDING and then INTRO

instead of START/STOP in Step 5 of

“Real-Time Recording.” Recording

starts with the intro pattern when

you play a note or a chord on the

accompaniment keys.

Track 1 is the main track, and you can

use it to record auto accompaniment

and drum pad sounds, as well as key-

board play. Tracks 2 through 6 are mel-

ody tracks, and you can use these for

recording a secondary melody that in-

cludes keyboard play and the drum pad.

• To start auto accompaniment during

a recording, press SYNCHRO/END-

ING instead of START/STOP in Step

5. Play the melody keys to start

recording. When you reach the point

where you want accompaniment to

start, play a chord on the accompa-

niment keys.

Because each track is independent of

the others, you only need to re-record a

single track if you make a mistake while

recording on it.

• To record while using free session,

between Step 4 and 5 of “Real-Time

Recording,” press FREE SESSION.

This makes the entire keyboard a

melody keyboard, regardless of the

MODE setting. See the “Free Ses-

sion Chord Progression Chart” on

Page 54.

REAL-TIME RECORDING

With real-time recording, the notes are

recorded as you play them on the key-

board. Before you start, read these tips.

• To record without an auto-rhythm,

USING MIDI

Your MD-1200 includes a feature called

MIDI (Musical Instrument Digital Inter-

face) — the universal standard for send-

ing and receiving performance data

between all types of electronic musical

instruments, regardless of manufactur-

er.

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 talk to each oth-

er in digital codes (instructions). One

MIDI device sends digital instructions

representing exactly what is being

played on it. The other MIDI device re-

ceives and translates those instruc-

tions, then produces (or records) the

sound exactly as it was played on the

first device.

Using MIDI, you can play music on your

MD-1200 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.

MAKING THE MIDI

CONNECTIONS

ABOUT MIDI

Your MD-1200 has MIDI OUT and IN ter-

minals. To connect your MD-1200 to an-

other MIDI-equipped device, you must

use a MIDI cable, available at your local

RadioShack store.

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

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 IN

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.

Download from Www.Somanuals.com. All Manuals Search And Download.

42-4041.fm Page 42 Tuesday, August 3, 1999 6:56 AM

Cautions:

• For detailed specifications of the

MIDI function, see the “MIDI Imple-

mentation Chart” on Page 58.

• Always turn off power to your MD-

1200 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 the MIDI

OUT and IN terminals. If you have

trouble plugging in the cable, do not

force it! You might damage the plug

or the instrument.

Notes:

• The pitch of a note depends on the

tone that is being used, as shown in

the “Note Table” on Page 52.

To send MIDI data from your keyboard,

use a MIDI cable to connect the MD-

1200’s MIDI OUT terminal to the other

device’s MIDI IN terminal.

• 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 receive MIDI data on your keyboard,

use a MIDI cable to connect the MD-

1200’s MIDI IN terminal to the other de-

vice’s MIDI OUT terminal.

Program Change specifies the tone.

Pitch Bend supplies pitch bend infor-

mation. A Pitch Bend operation on this

keyboard changes the pitch of the built-

in sound source and sends a Pitch Bend

message through the MIDI OUT terminal.

Note: You do not need to make both

connections if you are only either send-

ing or receiving.

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).

MIDI DATA

Your MD-1200 can send and receive

several different types of MIDI data. The

MD-1200’s tones, rhythms, and other

types of MIDI data are sent automatical-

ly as you play.

Notes:

• The

MD-1200’s

demonstration

tunes cannot be sent as MIDI data.

Entry (6 and 38) sets the contents of the

parameter. On the MD-1200, RPN is

used to set pitch bend range, transpose,

and tune control from an external MIDI

device.

Data Entry

6/38

Use the Bank Select setting to select the

MD-1200’s tone groups to be changed

by the Program Number message.

• Bank 0 — 0 to 127 (General MIDI

tones)

All Sound Off forces all sound on the

current channel to turn off, regardless of

how the sound is being produced.

• Bank 1 — 128 to 159 (synthesized

tones)

• Bank 2 — 160 to 167 (drum sets)

• Bank 3 — 168 to 199 (user tones)

All Notes Off turns off all note data sent

from an external device on the channel.

The notes being sustained by the pedal

continue to sound until the next pedal off

signal is received.

Just before sending a Program Change

message, send two Control Change

messages with this data to the MD-

1200:

Reset All Controllers initializes pitch

bend and all other control changes.

• Control Number = 0, Control Value =

• Control Number = 32, Control Value

• GM Mode On ([F0][7E][7F][09]

[01][F7]) — used to turn on the MD-

1200’s GM mode from an external

MIDI device.

Note: The contents of the System Ex-

clusive message affect the entire key-

board. Other messages affect only the

current MIDI channel.

Notes:

• GM (General MIDI) is a standard

list of specifications that allows

music created on one MIDI

device to sound the same when

played on another MIDI device.

This keyboard’s GM mode incor-

porates most of these specifica-

tions.

CHANGING MIDI

SETTINGS

The MD-1200 lets you change a number

of MIDI parameters, including turning

General MIDI mode on/off and selecting

a MIDI channel.

• This message takes more time to

process than other messages;

when you program GM Mode On

in the sequencer, leave at least a

100 msec pause before the next

message.

Follow these steps to change MIDI pa-

rameters.

1. Repeatedly press TRANSPOSE/

TUNE/MIDI until oFF GM Mode

appears.

• GM Mode Off ([F0][7E][7F][09]

[02][F7]) — used to turn off the MD-

1200’s GM mode.

GM Mode on/off (Default: Off): set to

on when you want to have the key-

board receive GM data from another

MIDI device. Turning GM mode on

automatically turns CHORD off,

since GM mode and MIDI In Chord

Judge cannot be used at the same

time.

3. Within 5 seconds, use + or – to

change the setting of the parameter.

DUMPING/IMPORTING

DATA

The MD-1200’s internal data, including

data recorded to memory and synthesiz-

er data, can be sent and received in bulk

as MIDI exclusive data through the MIDI

terminals. Thus, you can use a comput-

er or other MIDI device as an external

storage device.

Set to oFF to turn GM mode off.

The tone, volume and other param-

eter settings of each channel are ini-

tialized. When playing received

MIDI data, bass tones are lowered

one octave and the piccolo tone is

raised one octave.

First make connections from the MIDI IN

and MIDI OUT terminals to an external

device using MIDI cables.

Keybd Ch (Keyboard Basic Chan-

nel) (Default: 01): sets the channel

for sending MIDI data to an external

device.

Note: Some software does not support

Chord (MIDI In Chord Judge)

(Default: Off): when set to on, the

keyboard determines basic channel

note data as auto accompaniment

chords per the current chord finger-

ing method. Turning GM mode on

automatically turns Chord off,

since GM mode and MIDI In Chord

Judge cannot be used at the same

time.

MIDI exclusive data.

Dumping Data

Follow these steps to dump data from

the keyboard to an external device.

1. Put the other device in its receive

standby mode.

See the owner’s manual that comes

with the receiving device for details.

Local (Local Control) (Default:

On): set to on to send data simulta-

neously to the keyboard’s speakers

and as MIDI data. Set to oFF to

send data only as MIDI data (the

speakers on the keyboard remain

silent).

2. Repeatedly press TRANSPOSE/

TUNE/MIDI on the MD-1200 until the

display shows BulkSnd?.

3. Within 5 seconds, press

to start

data send. Sending appears. The

MD-1200 automatically exits the

data transfer mode after all the data

is sent.

AcompOut (Accompaniment Out)

(Default: Off): set to on to send auto

accompaniment as MIDI data. Set to

oFF to turn it off.

Mode — The chart shows that Mode 3 is

OMNI OFF, POLY. This means the MD-

1200 sends and receives polyphonic

data on only one channel at a time.

Importing Data

Follow these steps to import dumped

data from another device.

1. Repeatedly press TRANSPOSE/

TUNE/MIDI so the display shows

BulkSnd?.

Note Number — This number repre-

sents each key of the keyboard. The

lowest number (0) is five octaves below

middle C. Since the MD-1200’s lowest

note is two octaves below middle C and

the highest is three octaves above mid-

dle C, your keyboard can send a note

number between 36 and 96. But, it can

receive all 0 through 127 note numbers,

so those keys outside the MD-1200’s

key range are interpreted as notes in-

side the key range.

2. Within 5 seconds repeatedly press

so the display shows

BulkRcv?.

3. Within 5 seconds, press

to pre-

pare the keyboard to receive data.

4. Start the send operation on the

sending device. See the owner’s

manual that comes with the con-

nected device for details. The MD-

1200 automatically exits the data

transfer mode after all the data is

received.

Velocity — This number shows how

fast the key was pressed, or how loud

the note should sound. 1 is the lowest

velocity, pianissimo; 127 is the loudest,

fortissimo. 0 means the key is released.

NOTES ABOUT THE MIDI

IMPLEMENTATION

CHART

9n — This means that the Note On mes-

sage is 9 hexadecimal, and n is the

channel number.

The “MIDI Implementation Chart” on

Page 58 illustrates the details of the MD-

1200’s MIDI function. An O in the chart

means that the MD-1200 has this fea-

ture; X means it does not have this fea-

ture. This section explains what the MD-

1200 can do.

For example, if you select Channel 16

and press Key D in mezzo-piano, 9E (E

is 15 in hexadecimal; note that Channel

1 is 0 in MIDI data) is first sent from MIDI

OUT, then 3D (decimal 61) is sent as

the key number, finally 21 (decimal 33)

is sent as velocity.

Basic Channel — MIDI uses up to 16

channels to exchange data. As in a TV

broadcast, different channels send dif-

ferent data.

Pitch Bender — The MD-1200 sends

and receives 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 42.

Program Change

—

This feature

changes the preset sounds. Each sound

number corresponds to a program num-

ber between 0 and 127.

System Exclusive — This feature

sends special signals unique to the MD-

1200. For details, see “MIDI Data” on

Page 42.

System Real Time — “Clock” is like a

metronome to send the synchronizing

signal.

System real time commands send three

kinds of signals — start tells the key-

board to start playing from the begin-

ning, stop tells all the synchronized

instruments to stop playing, and contin-

ue is similar to start, but it signals the

music to begin at whatever point it was

last stopped.

All Notes Off — This feature is a kind of

panic button: it stops the sounds cur-

rently playing. The MD-1200 only re-

ceives this message.

Active Sensing — This means the MD-

1200’s sound turns off in the event the

connection cable to MIDI IN terminal is

accidentally disconnected.

CARE AND MAINTENANCE

Your

is an example of superior design and

Optimus MD-1200 Electronic Keyboard

craftsmanship. The following suggestions will help you care for your MD-1200 so

you can enjoy it for years.

Keep the MD-1200 dry. If it gets wet, wipe it dry immediately. Liquids

might contain minerals that can corrode the electronic circuits.

Use and store the MD-1200 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 MD-1200 away from dust and dirt, which can cause prema-

ture wear of parts.

Handle the MD-1200 gently and carefully. Dropping it can damage cir-

cuit boards and cases and can cause the MD-1200 to work improperly.

Use only fresh batteries of the required size and recommended type.

Batteries can leak chemicals that damage your MD-1200’s electronic

parts.

Wipe the MD-1200 with a damp cloth occasionally to keep it looking

new. Do not use harsh chemicals, cleaning solvents, or strong deter-

gents to clean the MD-1200.

Modifying or tampering with the MD-1200’s internal components can cause a mal-

function and might invalidate its warranty. If your MD-1200 is not performing as it

should, take it to your local RadioShack store for assistance.
