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.
BASS
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.
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.
• When rhythm or auto accompaniment is playing,
PIANO
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.
