FEATURES

Your Optimus MD-1200 Electronic Key-

board is a state-of-the-art musical instru-

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

accompaniments and percussion

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.

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.

PREPARATION

Note:

To connect a MIDI device, see

“Making the MIDI Connections” on

Page 41. To connect a sustain pedal,

see “Using a Sustain Pedal” on

Page 31.

CONNECTING POWER

You can power your MD-1200 from ei-

ther:

• 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.

• 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).

Using 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.

Cautions:

• Use only fresh batteries of the

required size and recommended

type.

• 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.

• Do not mix old and new batteries,

different types of batteries (stan-

dard, alkaline, or rechargeable), or

rechargeable batteries of different

capacities.

1. Press the tabs on the battery com-

partment cover, then pull up to

remove the cover.

2. Put the batteries in the compartment

as indicated by the polarity symbols

(+ and –) marked beside the com-

partment.

3. Replace the cover.

If the MD-1200 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.

42-4041.fm Page 7 Tuesday, August 3, 1999 6:56 AM

8

Using AC Power

You can power your MD-1200 from

standard AC power using a 9-volt AC

adapter (not supplied) and a Size M

Adaptaplug.

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.

• 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.

Follow these steps to power your MD-

1200 from AC power.

1. Insert the adapter’s barrel plug into

the

DC 9V

jack on the back of the

MD-1200.

2. Plug the adapter into a standard AC

outlet.

CONNECTING

HEADPHONES

To listen to your MD-1200 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.

To connect a pair of headphones, insert

the headphones’

1

/

4

-inch (6.35-mm) plug

into the

PHONES/OUTPUT

jack on the

back of the keyboard.

Note:

Connecting headphones discon-

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

Listening Safely

To protect your hearing, follow these

guidelines when you use headphones.

• Set the volume to the lowest setting

before you begin listening. After you

begin listening, adjust the volume to

a comfortable level.

• Do not listen at extremely high vol-

ume levels. Extended high-volume

listening can lead to permanent

hearing loss.

!

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

9

• 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

1

/

4

-inch (6.35-mm) plug.

To connect an external amplifier to your

keyboard, insert the cable’s

1

/

4

-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.

USING THE PRESET

TONES

Your MD-1200 can sound like 200 differ-

ent musical instruments or sound ef-

fects. The name and three-digit number

of each preset tone is listed on the MD-

1200’s top panel.

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.

Many of the keyboard’s preset

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.

Follow these steps to select and play a

preset tone.

1. Press

TONE

.

TONE

and the current

tone’s number appear.

Note:

The MD-1200 automatically

selects the tone GRAND PIANO

(No. 000) the first time you turn on

power.

2. To play a different tone, choose a

preset tone from the 200 TONES list

and enter its three-digit number on

the keypad. For example, to select

ELEC PIANO 1, press

0 0 4

. As you

press the keys, the selected digits

appear.

USING THE PRESET

AUTO-RHYTHMS

Your MD-1200 has 100 preset auto-

rhythms that provide a steady beat for

your music. The name and two-digit

number of each preset auto-rhythm is

marked to the left of the MD-1200’s dis-

play.

You can play a preset auto-rhythm on

the MD-1200 in any of these ways:

• Select and play a rhythm. See

“Selecting/Playing an Auto-

Rhythm.”

duction. See “Using INTRO” on

Page 17.

• Stop a rhythm with a special ending.

See “Using ENDING” on Page 17.

• Briefly vary the pattern of a rhythm.

See “Using FILL-IN” on Page 17.

Concert Chord

The concert chord method lets begin-

ning keyboard players easily select and

play a chord.

The number of accompaniment keys

you press determines the type of chord

that plays. This table shows the type of

chord that plays when you press one,

two, three, or four accompaniment keys

at the same time.

The lowest note you play determines the

key of the chord. For example, if the low-

est note is C, the keyboard plays a C

chord.

Note:

You can play any labeled note(s)

to the right of the lowest note in the

chord to produce a minor, a dominant

seventh, or minor seventh chord.

Follow these steps to start concert chord

auto accompaniment.

1. Set

MODE

to

CONCERT CHORD

.

2. Select and enter an auto-rhythm.

3. To start the auto-rhythm before the

auto accompaniment, press

START/

STOP

or

INTRO

.

To synchronize the start of the

selected auto-rhythm with your

accompaniment, press

SYNCHRO/

ENDING

.

4. Begin the accompaniment by press-

ing the desired accompaniment

key(s).

To play a melody along with the

accompaniment, press any key(s) to

the right of the accompaniment

keys.

5. To change chords without interrupt-

ing the rhythm, simply press the

auto accompaniment key(s)

required to form the new chord.

6. To stop accompaniment and the

auto-rhythm, press

Standard Fingering

The standard fingering method uses standard formations of three or four notes, and

lets the experienced musician play a wider variety of accompaniment chords. You

can play these 15 chord types on your MD-1200, in any key, using the standard fin-

gering method.

Notes:

• To produce a simple variation of a 7, m7, M7, mM7, add9, or madd9 chord, you

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.
