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-7 for full details.
Sound Effect Tones
With sound effect tones 77 through 79, the type of
sound produced depends on the octave where the
key you press is located. When 78 PHONE is
selected available sound types are PUSH TONE 1,
PUSH TONE 2, RING 1, and RING 2.
Polyphony
The term polyphony refers to the maximum
number of notes you can play at the same time.
The 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.
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, 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.
