Using standard fingerings
The FINGERED mode lets you play a wider variety of chords. In this mode, you can start play of an accompaniment pattern by pressing three or four of the accompaniment keyboard keys. This keyboard is capable of recognizing 15 different chords. The following shows the fingerings of these chords with a root of C. Note that you can omit the fifth notes (which are shown inside parentheses in the illustrations below) to produce 7, m7, M7, add9, madd9, and mM7 chords.
The bottom (leftmost) note that you play determines the name of the chord. If the bottom note is a C for example, the keyboard produces a C chord. When pressing more than one accompaniment key, it makes no difference whether the keys to the right of the bottom note are white or black.

Caug (*1)

To play a CASIO CHORD auto-accompaniment
Use the POWER/MODE selector to select CASIO CHORD. C(*1) Select an auto-rhythm as described under To select and play a rhythm on page E-18. Start play of the rhythm.

C7sus4

Cmadd9

Cdim7 (*1)

Press either one or up to four keys on the accompaniment keyboard, and the corresponding accompaniment starts to play automatically.
*1 With this chords, the lowest note in your fingering is always used as the root. Make sure that your fingering correctly identifies the root you want to use.

Chord name

662A-E-021A
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 autochords only work in conjunction with rhythm patterns, and not independently of them.
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.
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.

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.

Accompaniment keyboard

Set the POWER/MODE selector to the CASIO CHORD or FINGERED position. Select an auto-rhythm. Press the SYNCHRO/FILL-IN button. Press the accompaniment keys to play the first chord. As soon as you do, the autoaccompaniment pattern begins to play.

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.
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.
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.
To play a built-in Song Bank tune
Look up the number of the tune you want to play in the Song Bank list. 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.
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.

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.
Step 3: Play at normal speed
At this level, the keyboards 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.
Press the START/STOP button to start play of the selected tune.
The tune you select plays repeatedly, with the keyboard keys lighting to indicate the melody notes.

Try pressing any one of the keyboard keys in place of the ONE KEY PLAY buttons.
Pressing any keyboard key plays the correct melody (right hand part) note. Pressing more than one key at the same time counts as a single melody note. Pressing a key while another key is held down is counted as two melody notes.
Input a value to select the tone you want to use.
Selecting another Song Bank tune switches the tone setting to the newly selected tunes 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 84 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.
The correct note is played even if you do not press the key that is lit.
To stop play at any time, press the START/STOP button.
When you do, the STEP 1 indicator goes out.

662A-E-026A

When you do, the STEP 3 indicator appears. Play starts after a count sounds.
Play along on the keyboard, following the keys as they light.
The accompaniment (left hand) part of the tune plays at normal speed, regardless of what you play on the keyboard. With an auto-accompaniment tune, the keyboard key that corresponds to the next note to be played flashes, and lights when the note should be played. With a two-hand tune, the applicable keyboard key remains lit as long as its note plays. In this case, however, the key for the next note to be played does not flash. Keys light when their notes start to play.
Play the notes indicated by the 3-Step Lesson System.
Press keyboard keys as they light. More than one key may light when you are playing a two-hand tune. Press all keys that light.

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.

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.

MIDI Connections
