Improvising with the preset patterns
Pressing the START/STOP button to start rhythm play causes
the normal version of the pattern to be played. You can also
play a variation of the rhythm using the operation described
below.
Using fill-in rhythm
You can insert a fill-in rhythm by pressing the SYNCHRO/
FILL-IN button while an auto-rhythm plays.
Using Synchro start
You can start the rhythm and accompaniment pattern at the
same time, with your play of the accompaniment keyboard.
To do this, follow the steps below.
1.Set the POWER/MODE selector to the CASIO
CHORD or FINGERED position.
2.Select an auto-rhythm.
3.Press the SYNCHRO/FILL-IN button.
4.Press the accompaniment keys to play the first
chord. As soon as you do, the auto-
accompaniment pattern begins to play.

page E-18, the operation in step 4 starts play of the rhythm
(percussion instruments) only.
662A-E-022A
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
662A-E-023A
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 auto-
accompaniment (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 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
in the Song Bank list.
2.Press the SONG BANK button until the SONG
BANK indicator appears.
•This causes the number and name of the currently
selected Song Bank tune to appear on the display.
3.Input the two digit number for the tune you want
to play.
Example: To select “13 TWINKLE TWINKLE LITTLE
STAR”, input 1 and then 3.

Voice Fingering Guide
Voice fingering guide uses a simulated human voice to call
out fingering numbers during Step 1 and Step 2 one-hand
part practice. If you need to press a key with your thumb, for
example, voice fingering guide says, “One!” In the case of a
chord to be played with your thumb, middle and little finger,
voice fingering guide says, “One, three, five!”
Voice Fingering Guide calls out fingerings only when you do
not press the proper key when you should.
To turn voice fingering guide on and off

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.

❚ NOTE
•Note length is not indicated when you are using two-hand tunes
(84 to 99) with 3-Step Lesson Steps 1 and 2. As soon as you
press a lit key, it goes out and the next key to be played starts
to flash.
•Note length is indicated by the key light system when you use
a two-hand tune with Step 3. In this case, the next key to be
pressed does not flash when you press a lit key and the next
finger number does not appear on the display. Only the current

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
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.
