and personal injury.

AUX IN or similar terminal
of audio amplifier

Connect the keyboard to a audio equipment using a commercially
available connecting cord with a standard plug on one end and two
PIN plugs on the other end. Note that the standard plug you connect
to the keyboard must be a stereo plug, otherwise you will be able to
output only one of stereo channels. In this configuration, you normally set the input selector of the audio equipment to the terminal
(usually marked AUX IN or something similar) where the cord from
the keyboard is connected. See the user documentation that comes
with your audio equipment for full details.
Musical Instrument Amplifier (Figure 3)
Use a commercially available connecting cord to connect the keyboard
to a musical instrument amplifier.

❚ NOTE ❚
Be sure to use a connecting cord that has a stereo standard plug on the
end you connect to the keyboard, and a connector that provides dual channel (left and right) input to the amplifier to which you are connecting. The
wrong type of connector at either end can cause one of the stereo channels to be lost.

When connected to a musical instrument amplifier, set the volume of
the keyboard to a relatively low level and make output volume adjustments using the amplifier’s controls.

The keyboard may not function correctly if you load or replace batteries with power turned on. If this happens, turning the keyboard
off and then back on again should return functions back to normal.

Important Battery Information
■ The following shows the approximate battery life.
Manganese batteries ................ 2 hours
The above value is standard battery life at normal temperature,
with the keyboard volume at medium setting. Temperature extremes or playing at very loud volume settings can shorten battery life.
■ Any of the following symptoms indicate low battery power. Replace batteries as soon as possible whenever any of the following occurs.
• Dim power supply indicator
• Instrument does not turn on
• Display that is flickering, dim, or difficult to read
• Abnormally low speaker/headphone volume
• Distortion of sound output
• Occasional interruption of sound when playing at high volumes
• Sudden power failure when playing at high volumes
• Flickering or dimming of the display when playing at high
volume
• Continued sound output even after you release a key
• A totally different tone may sound
• Abnormal rhythm pattern and Song Bank play
• Loss of power, sound distortion, or low volume when playing
from a connected computer or MIDI device

AC output

Also note the following important warnings and precautions when
using the AC adaptor.

WARNING!
• Take care to avoid any damage to or breakage of the power cord. Never
place any heavy objects on the power cord or expose it to direct heat.
Doing so creates the danger of power cord damage, fire, and electrical
shock.
• Use only the specified AC adaptor. Use of another type of adaptor creates the danger of fire and electrical shock.

CAUTION!
• For safety sake, be sure to unplug the AC adaptor from the wall outlet
whenever leaving the keyboard unattended for a long time (such as
when leaving on a trip).
• Always turn off the keyboard and unplug the AC adaptor from the wall
outlet when you are not using the keyboard.

IMPORTANT!
• Make sure that the keyboard is turned off before connecting or
disconnecting the AC adaptor.
• Using the AC adaptor for a long time can cause it to become warm
to the touch. This is normal and does not indicate malfunction.

Combination tones
The following describes the two types of combination tones that are
available.

Layered Tones (Tone Numbers: 80 through 89)
Example: 80 STR PIANO
This tone layers a strings tone with a piano tone so they both sound
when a keyboard key is pressed.

Split Tones (Tone Numbers: 90 through 96)

Selecting a Tone

Example: 90 BASS/PIANO

This keyboard comes with 100 built-in tones. Use the following procedure to select the tone you want to use.

This tone splits the keyboard so one range is assigned a bass tone
and another range is assigned a piano tone.

Polyphony
The term polyphony refers to the maximum number of notes you can
play at the same time. The keyboard has 12-note polyphony, which
includes the notes you play as well as the rhythms and auto-accompaniment patterns that are played by the keyboard. This means that
when a rhythm or auto-accompaniment pattern is being played by
the keyboard, the number of notes (polyphony) available for keyboard play is reduced. Also note that some of the tones offer only 6note polyphony.
• When rhythm or auto accompaniment is playing, the number of
sounds simultaneously played is reduced.

Digital Sampling
A number of the tones that are available with this keyboard have
been recorded and processed using a technique called digital sampling. To ensure a high level of tonal quality, samples are taken in the
low, mid, and high ranges and then combined to provide you with
sounds that are amazingly close to the originals. You may 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 sampling, and it is not a sign of malfunction.

keyboard, because they are the names that are most commonly used
in musical notation.

Chord Names

Inverted Forms

Chords are named using upper-case letters from A through G, which
indicate the root note of the chord. If the root note is a sharp or flat,
the chord itself is sharp or flat. A chord name may also be followed
by a degree number or other symbols that indicate certain characteristics about the chord.

There are a number of different ways to play the same chord. A form
that is different from the basic form but still produces the same chord
is called an “inverted form.”

• The fingering that appears on the display is one standard
fingering. You can also use other fingerings to match the size
of your hands or to make it easier to progress from or to
neighboring chords.
• You can also use the [+] and [–] buttons to change the displayed chord name.
• The tone used to sound chords you play on the accompaniment keyboard while using the Chord Book is the same tone
used by the accompaniment part of the rhythm that was selected before you entered the Chord Book mode. Depending
on the rhythm that was selected, some of the notes that make
up a chord may be omitted when you play the chord on the
accompaniment keyboard in the Chord Book Mode. This is
due to the internal chord conversion function, arrangements,
and polyphony limitations. Because of this, you should always play the chords indicated on the display on the melody keyboard (the range that does not have chord names printed above the keys).

• Since the chord fingerings that appear on the display are selected to
allow chord play within the accompaniment keyboard, inverted chord
forms (page E-26) are often suggested. Inverted chord forms are useful
to help you learn how to play chord variations that make it possible to
move from one chord to another with minimal hand movement. These
forms come in handy when using FINGERED Auto Accompaniment play.
• While a chord name is on the display, you can press keys on the accompaniment keyboard to find out the fingerings of the same chord with a
different root.
• You can also scroll through chord names using the [+] and [–] buttons.
• Chord fingerings that appear on the display are formed using only the
keys within the range of the accompaniment keyboard (leftmost 18 keys).
Chords that cannot be formed using the keys within this range are not
displayed.

Tuning the Keyboard

Transpose lets you raise and lower the overall key of the keyboard in
semitone units. If you want to play an accompaniment for a vocalist
who sings in a key that’s different from the keyboard, for example,
simply use transpose to change the key of the keyboard.

The tuning feature lets you fine tune the keyboard to match the tuning of another musical instrument.

MIDI
What is MIDI?

General MIDI

The letters MIDI stand for Musical Instrument Digital Interface, which
is the name of a worldwide standard for digital signals and connectors that makes it possible to exchange musical data between musical instruments and computers (machines) produced by different
manufacturers. MIDI compatible equipment can exchange keyboard
key press, key release, tone change, and other data as messages.
Though you do not need any special knowledge about MIDI to use
this keyboard as a stand-alone unit, MIDI operations require a bit of
specialized knowledge. This section provides you with an overview
of MIDI that will help to get you going.

General MIDI standardizes MIDI data for all sound source types, regardless of manufacturer. General MIDI specifies such factors as tone
numbering, drum sounds, and available MIDI channels for all sound
sources. This standard makes it possible for all MIDI equipment to
reproduce the same nuances when playing General MIDI data, regardless of the manufacturer of the sound source.
Though the sound source of this keyboard is not General MIDI compatible, you can still connect the keyboard to a computer or other
MIDI equipment to playback General MIDI data that is widely available in stores, over computer networks, and from other sources.

❚ NOTES ❚

MIDI Connections
MIDI messages are send out through the MIDI OUT terminal of one
machine to the MIDI IN terminal of another machine over a MIDI
cable. To send a message from this keyboard to another machine, for
example, you must use a MIDI cable to connect the MIDI OUT terminal of this keyboard to the MIDI IN terminal of the other machine. To
send MIDI messages back to this keyboard, you need to use a MIDI
cable to connect the other machine’s MIDI OUT terminal to the MIDI
IN terminal of this keyboard.
To use a computer or other MIDI device to record and playback the
MIDI data produced by this keyboard, you must connect the MIDI
IN and MIDI OUT terminals of both machines in order send and receive data.

• General MIDI data made up of a large number of parts may not play
correctly on this keyboard.
• You will have most success playing back General MIDI data that has
few parts and is made up of data on channels 1, 2, 3, 4, and 10.

Messages
There is a wide variety of messages defined under the MIDI standard, and this section details the particular messages that can be sent
and received by this keyboard.

NOTE ON/OFF
This message sends data when a key is pressed (NOTE ON) or released (NOTE OFF).
A NOTE ON/OFF message include a note number (to indicate note
whose key is being pressed or released) and velocity (keyboard pressure as a value from 1 to 127). NOTE ON velocity is always used to
determine the relative volume of the note. This keyboard does not
receive NOTE OFF velocity data.
Whenever you press or release a key on this keyboard, the corresponding NOTE ON or NOTE OFF message is sent by constant velocity
from the MIDI OUT terminal.

❚ NOTE ❚

MIDI Channels
MIDI allows you to send the data for multiple parts at the same time,
with each part being sent over a separate MIDI channel. There are 16
MIDI channels, numbered 1 through 16, and MIDI channel data is
always included whenever you exchange data (key press etc.)
Both the sending machine and the receiving machine must be set to
the same channel for the receiving unit to correctly receive and play
data. If the receiving machine is set to Channel 2, for example, it receives only MIDI Channel 2 data, and all other channels are ignored.
With this keyboard, messages received over MIDI Channels 1, 2, 3, 4,
and 10 can be used for multi-timbre play of up to five different instrument parts. The tone and volume settings for these five channels
must be controlled by messages sent from an external device.
When sending operation of this keyboard to an external device, Channel 1 should be selected as the MIDI send channel.

The pitch of a note depends on the tone that is being used, as shown in
the Note Table on page A-1. Whenever this keyboard receives a note number that is outside its range for that tone, the same tone in the nearest
available octave is substituted.

PROGRAM CHANGE
This is the tone selection message. PROGRAM CHANGE can contain tone data within the range of 0 to 127.
A PROGRAM CHANGE message (0 to 99) is sent out through this
keyboard’s MIDI OUT terminal whenever you manually change its
tone number. Receipt of a PROGRAM CHANGE message from an
external machine changes the tone setting of this keyboard (page E31).
This keyboard can send tone data within the range of 00 to 99 and
receive tone data within the range of 0 to 127.

PITCH BEND
This message carries pitch bend information for smoothly sliding the
pitch upwards or downwards during keyboard play. This keyboard
does not send pitch bend data, but is can receive such data.
