Making Detailed Settings for the ONE TOUCH Tones
This adjusts the sound of the sympathetically vibrating aliquot
strings on an acoustic piano.
When the keys are pressed on an acoustic piano, the strings
for keys that are already pressed also vibrate sympathetically.
The function used to reproduce is called “String Resonance.”
This adjusts resonances such as the key-off sound of an
acoustic piano (subtle sounds that are heard when you release
a key).
This adjusts the sound of the hammer striking the string of an
acoustic piano.
Changes the pitch using the “stretch tune” method typically
used on acoustic pianos. This makes high-range sounds
slightly higher in pitch, and low-range sounds slightly lower in
pitch.
Adjusting the Resonance of the Aliquot
Strings (Duplex Scale)
Parameter
Value Description
Duplex Scale
0–127
Higher values will increase
the volume of the sympathetic
vibration.
Adjusting the Resonant Sounds
when the Keys are Pressed
(String Resonance)
Parameter
Value Description
String Resonance
OFF,
1–127
Increasing the value will
increase the amount of effect.
What are Duplex Scale?
The Duplex Scale is a system of sympathetically vibrating
strings sometimes included in grand pianos.
These sympathetically vibrating strings are not struck
directly with hammers, but sound by vibrating in
sympathy with the vibrations of other strings. By
resonating with the overtones, these strings add richness
and brilliance to the sound. These sympathetic strings are
added only to the high register above approximately C4.
Since they do not have a damper (a mechanism that
stops them from sounding), they will continue sounding
even after you play a note and then release it to stop the
sound of the string that was actually struck.
Adjusting the String Resonance
Produced when a Key is Released
(Key Off Reso.)
Parameter
Value Description
Key Off Reso.
(Key Off
Resonance)
OFF,
1–127
Higher values will increase
the volume of the
resonances.
Adjusting the Sound of the Hammer
Strike (Hammer Noise)
Parameter
Value Description
Hammer
Noise
-2–0–+2
Higher values will increase
the sound of the hammer
striking the string.
