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.

BASS/PIANO (No.90)

BASS PIANO

PERCUSSION (No.99)

• PERCUSSION (Tone 99) assigns 35 percussion sounds and

five voice sounds to the keyboard as shown below. The

Digital Sampling

A number of the tones that are available with this keyboard

have been recorded and processed using a technique called

digital sampling. To ensure a high level of tonal quality,

samples are taken in the low, mid, and high ranges and then

combined to provide you with sounds that are amazingly

close to the originals. You may notice very slight differences

in volume or sound quality for some tones when you play

them at different positions on the keyboard. This is an

unavoidable result of multiple sampling, and it is not a sign

of malfunction.

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.

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.

While in any mode besides the Song Bank Mode

(indicated when the SONG BANK indicator is

lit), hold down the TONE button and press the

RHYTHM button.

• Perform step 2 within five seconds after performing

step 1.

Use the TEMPO buttons to change the key of

the keyboard.

Example: To change the tuning to B (indicated by -1

since it is one tone below C, which is the

normal tuning of the keyboard).

• If you leave the transpose screen on the display for about five

seconds without doing anything, the screen is automatically

range of the tone you are using, the same note in the highest

octave of the tone’s range is substituted.

• The transpose operation does not affect tone number 99

(PERCUSSION) or auto-accompaniment rhythms.

• Transposing tones 75 through 79 and 90 through 96 changes

the range of keys to which each of the tones is assigned.

• The transpose setting is automatically set to C(0) whenever

you press the DEMO button.
