BASSPIANO
PERCUSSION (No.99)
•PERCUSSION (Tone 99) assigns 35 percussion sounds and
five voice sounds to the keyboard as shown below. The
sounds assigned to each key are indicated above the
keyboard.
662A-E-017A
❚ NOTE
•Always enter two digits for the tone number. If you enter only
one digit, the display will automatically return to the previous
tone number setting after a few seconds.
•If you change the tone setting while a keyboard key is
depressed, the tone does not change until you release the key
and press a keyboard key again.
•With certain tones (such as percussion sounds and sound
effects), there may be very little or no change at all in the pitch,
no matter which keyboard key you press.
•If you input the wrong first digit for a tone number, you can
return to the previous setting by pressing the TONE button.
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 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 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.

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.
