Keyboard split tones

Some of the preset tones split the keyboard and assign two
or more sounds. With such a preset tone, the sound produced
depends on what position of the keyboard you play. For
example, BASS/PIANO (tone 90) puts BASS on the left and
PIANO on the right of the keyboard.

Polyphony

The term polyphony refers to the maximum number of notes
you can play at the same time. This 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 auto­accompaniment 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 6-note
polyphony.

• When rhythm or auto accompaniment is playing, the
number of sounds simultaneously played is reduced.

• Though you can sound up to 12 notes at one time, only the
last four keyboard keys pressed light up.

Other Useful Functions

To change the key of the keyboard

The transpose feature of this keyboard lets you raise or lower
its key in semitone increments. This means you can easily
match to suit someone’s voice, and you can eliminate sharps
and flats from music making it easier to play.

play. FINGERED lets you play chords as you normally do,
while CASIO CHORD makes it possible to play fully formed
chords with one finger.

About the accompaniment keyboard

The lower (left) 1.5 octaves are reserved for use as an
accompaniment keyboard whenever you select CASIO
CHORD or FINGERED with the POWER/MODE selector.
The panel above the accompaniment keyboard keys is marked

• If you play one or two notes only in the left hand, or three
notes that do not make up a recognizable chord formation,
no sound will be produced. The FINGERED mode requires
a conventional three or four-note chord formation to

Using 3-Step Lesson System

Even individuals who cannot play the keyboard at all can
follow along with the 100 built-in Song Bank tunes with the
ONE KEY PLAY buttons. You can also use the 3-Step Lesson
System to learn at your own pace. Play slowly at first until
you are able to play along at normal speed.
Of the 100 built-in tunes, numbers 00 through 83 feature auto­accompaniment (auto-accompaniment tunes), while 84
through 99 are played using both hands (two-hand tunes).

The 3-Step Lesson System can be used with the following 3­step lesson plan to master keyboard play.

Step 1: Master the timing

Pressing the ONE KEY PLAY buttons plays the
melody for an auto-accompaniment tune or the right
hand part for two-hand tunes. In both cases, the auto­accompaniment (the left hand part in the case of two­hand tunes) is played automatically by the keyboard.
In place of the ONE KEY PLAY buttons, you can also
press any key of the keyboard to play the melody or
right hand part. The purpose of this step is to
familiarize yourself with the timing required to play
melody notes.

Step 2: Master the melody

In this step, you use the display to learn which fingers
you should use to play, and the key light system to
learn which keyboard keys to press. You can play at
the pace you want, because the auto-accompaniment
or left hand part waits until you press the correct key.

Step 3: Play at normal speed

At this level, the keyboard’s keys still light to indicate
which notes to play, but they no longer wait for you
to press the correct key. The auto-accompaniment or
left hand part is played at normal speed.

MIDI

What is 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 Connections

MIDI IN MIDI OUT

MIDI IN MIDI OUT

Computer etc.

General MIDI

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.

❚

NOTE

• 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 parts 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 includes a note number (to
indicate note whose key is being pressed or released) and
velocity (velocity=100 when the volume value of this unit is
9 to 2, and velocity=75 when the volume value is 1 or 0).
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.

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.
This keyboard can send tone data within the range of 00 to
99 and receive tone data within the range of 0 to 127*. Each
of the 128 General MIDI tones is automatically assigned to
one of the keyboard’s 100 built-in tones as shown on page A-

1. Select this setting when you want to listen to General MIDI
data from a computer or other external equipment.

* When GM mapping is turned on (page E-28). When turned

off, tone data is received in the range of 0 to 99.

❚

NOTE

• Channel 10 is for the drum part only, and it does not receive
Program Change messages. When receiving MIDI data, it
sounds percussion sounds produced by this keyboard.

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 it can
receive such data.

CONTROL CHANGE

This message adds effects such as vibrato and volume changes
applied during keyboard play. CONTROL CHANGE data
includes a control number (to identify the effect type) and a
control value (to specify the on/off status and depth of the
effect).
The following is a list of data that can be received using
CONTROL CHANGE.

internal sound source and simultaneously output as a
MIDI message from the MIDI OUT terminal.

oFF: Anything played on the keyboard is output as a MIDI

message from the MIDI OUT terminal, without being
sounded by the internal sound source. Turn LOCAL
CONTROL off whenever you are using the MIDI THRU
function of a computer or other external device. Also
note that no sound is produced by the keyboard if
LOCAL CONTROL is turned off and no external device
is connected.

* Multiple digital samples are taken for the low range, middle range, and high range of

the original musical instrument. Because of this, there may be a very slight difference
in tonal quality and volume between sample ranges.
