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.

3.
Use the number buttons to input the 2-digit
number that identifies the tone you want to
select.
Example: To select 26 ACOUSTIC BASS, input 2 and
then 6.
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.

BASS/PIANO (No.90)

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 someones 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.
2.
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).

NOTE
If you leave the transpose screen on the display for about five
seconds without doing anything, the screen is automatically
cleared.
You cannot change the transpose setting while the keyboard is
in the Song Bank Mode.
In step 2 of the above operation, you could also use the number
buttons 0 to 5 to specify C through F.

The transpose setting is automatically set to C(0) whenever
you turn keyboard power on.
The transpose setting is automatically set to C(0) whenever
you press the SONG BANK button.
The pitch of a transposed note depends on the tone you are
using. If the transpose operation causes a note to exceed the
range of the tone you are using, the same note in the highest
octave of the tones 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.
