Notes:
The keyboard has 16-note (maxi-
mum) polyphonic sound. This
means that you can play up to 16
different notes at the same time with
most of the keyboard’s preset tones.
Some of the keyboard’s preset
tones, however, are capable of only
8-note polyphony.
Most tones on this keyboard have
been recorded and processed using
a technique called digital sampling.
To ensure a high level of tonal qual-
ity, samples are taken in the low,
mid, and high ranges and are then
combined to sound amazingly close
to the originals. You might 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 unavoid-
able result of multiple sampling and
is not a malfunction.
Some sound effect tones, such as
PERCUSSION (No. 99), do not fol-
low the musical scale when played,
but change effect as you play them
in different octaves on the keyboard.

Keyboard Split Tones
The preset tones numbered 90 through
96 on your keyboard let you automati-
cally play two different musical instru-
ments or sound effects independently
on opposite sides of the keyboard.
The instrument listed first in the tone’s
name plays on the left half of the key-
board (below middle C). The instrument
listed next plays on the right half of the
keyboard (above middle C). For exam-
ple, BS/PNO (No. 90) plays a bass tone
on the left half of the keyboard and a pi-
ano tone on the right.
