Combination tones
The following describes the two types of combination tones
that are available.
Layered Tones (Tone Numbers: 80 through 89)
Example: 80 STR PIANO
This tone layers a strings tone with a piano tone so they both
sound when a keyboard key is pressed.
Split Tones (Tone Numbers: 90 through 96)
Example: 90 BASS/PIANO
This tone splits the keyboard so one range is assigned a bass
tone and another range is assigned a piano tone.
Percussion sounds
Example: 99 PERCUSSION
This tone assigns various percussion sounds to the keyboard.
See the Percussion Instrument List on page A-5 for full de-
tails.
Sound Effect Tones
With sound effect tones 77 through 79, the type of sound pro-
duced depends on the octave where the key you press is lo-
cated. When 78 PHONE is selected available sound types are
PUSH TONE 1, PUSH TONE 2, RING 1, RING 2, and BUSY
SIGNAL.
Polyphony
The term polyphony refers to the maximum number of notes
you can play at the same time. The keyboard has 12-note po-
lyphony, 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.
NOTE
When rhythm or auto accompaniment is playing, the number
of sounds simultaneously played is reduced.

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, sam-
ples are taken in the low, mid, and high ranges and then com-
bined 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 unavoid-
able result of multiple sampling, and it is not a sign of mal-
function.
