Using auto-accompaniment
This keyboard features 50 accompaniment patterns that let 
you add full accompaniments to your performances 
automatically. With auto-accompaniment, part of the
keyboard is reserved as an accompaniment keyboard. As you 
play your chords on the accompaniment keyboard, the 
accompaniment pattern adjusts automatically to follow the
progression you play. 
You get a choice between two different methods for chord 
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 
with the names of the notes they play. The remainder of the
keyboard (the part that is not included in the accompaniment 
keyboard) is called the melody keyboard. Please be sure to 
remember these terms, because they will be used throughout
the rest of this manual.
Accompaniment keyboard Melody keyboard
The entire keyboard can be used for melody play while 
the POWER/MODE selector is set to NORMAL.(                                                       )
Using the CASIO CHORD system
The CASIO CHORD system lets you easily play the four main
types of chords. Play of chords is simplified as shown in the

IMPORTANT!
•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 
produce an auto-accompaniment. Also, note that auto-
chords only work in conjunction with rhythm patterns, and 
not independently of them.
❚ NOTE
• The above examples show only one of the possible fingerings
for each chord. Note that you can play the notes that form a 
chord in any combination. Each of the following fingerings for
example, produces the same C chord.

3-Step Lesson System
640A-E-024A
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 84 feature auto- 
accompaniment (auto-accompaniment tunes), while 85
through 99 are played using both hands (two-hand tunes). 
The 3-Step Lesson System can be used with the following 3- 
step 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 auto- 
accompaniment (the left hand part in the case of two- 
hand 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.
❚ NOTE
• You may not be able to see the keyboard keys light under direct 
sunlight or in other brightly lit areas.
• You can press the ONE KEY PLAY, STEP 1, STEP 2, and STEP
3 buttons at any time, except while a demo tune is playing. To 
return the keyboard to its normal mode, press the SONG BANK 
button.
3-Step Lesson System Tempo Setting
You can use the procedure in step 6 of the procedure on page 
E-19 to set the tempo of the left-hand part for Song Bank and 
3-Step Lesson System play (Step 1 through 3). 
This means you can use a slower tempo at the beginning,
and then increase it as you learn. Press both of the TEMPO 
buttons (
 and ) at the same time to return the tempo to
its initial preset setting.
To play a built-in Song Bank tune
1.Look up the number of the tune you want to play

Timing Indicator
The timing indicator helps you become familiar with tunes 
you are playing for the first time by indicating the timing of 
notes you play on the keyboard. Timing is easier to see when 
you use a slow tempo during lesson play.
Using the Timing Indicator
The timing indicator shows the timing of notes contained in 
the currently selected part (R or L). Notes are indicated as 
two-segment blocks that scroll from the top of the display,
down to the bottom. A note is played when its block reaches 
the bottom of the display. 
• Each two-segment block can indicate one or more notes, 
depending on the tune you are playing.
❚ NOTE
• The Timing Indicator shows note timing whenever you play back 
a Song Bank tune and during a 3-Step Lesson.
• Note that the Timing Indicator shows approximate timing only.
During a tune, the indicated timing can be anywhere from an 
eight note to a 32nd off of actual timing.
Turning Off Key Lighting
1.Press the KEY LIGHT button.
•The KEY LIGHT indicator disappears when the key
light system is turned off.
• Press the KEY LIGHT button again to turn key lighting
back on.
❚ NOTE
Key lighting turns on automatically in any of the following cases: 
• When keyboard power is turned on.
• When demo tune play is started.
• When the SONG BANK button is pressed in the normal mode 
(page E-22).
• When the power on alert function operates (page E-13).
Number of Simultaneously Lit Keys
Up to four keyboard keys can be lit at the same time.
To change the tone used for the melody 
of a Song Bank tune

press the TONE button.
•Both the SONG BANK indicator and TONE indicator
appear, along with the tone number and name of the 
tone that is currently assigned to the keyboard.
2.Input a value to select the tone you want to use.
❚ NOTE
• Selecting another Song Bank tune switches the tone setting to 
the newly selected tune ’s preset melody tone.
• The tone assigned to the keyboard is the same one specified 
for the melody of the Song Bank tune.
• The above procedure can be used to change the Song Bank
melody tone before starting play or while play is already in
progress.
• You can also change the tone of two-hand tunes (tune numbers
85 to 99). Note however, that selecting a sustainable tone (like
an organ tone) when using 3-Step Lesson Step 1 or Step 2 (in
which accompaniment waits for correct input from you before
proceeding), can cause notes of the auto accompaniment to
be sustained while the keyboard is waiting for your input. If this 
happens, play something on the keyboard to stop the sustained 
note.
