Detailed Settings for Each Function ([EDIT])

Creating Smooth Pitch Changes 
(Portamento Switch/Time)
 
Portamento is a function that causes the pitch to change 
smoothly from one note to the next note played.
With the Mono/Poly parameter set to Mono, portamento is 
especially effective when simulating playing techniques such 
as a violin glissandos.
The Portamento Time setting determines the time for the 
change in pitch when the portamento effect is applied to the 
sound. Higher settings will cause the pitch change to the next 
note to take more time.
 
Changing Tone Elements
 
You can make changes in tones by adjusting the settings of 
the following four elements.
 
Attack Time:
 
The time it takes after the key is pressed for a sound to reach 
full volume.
 
Release Time:
 
The time it takes after the key is released for a sound to 
become inaudible.
 
Cutoff: 
 
Adjusts how much the filter is opened.
 
Resonance: 
 
Emphasizes the overtones in the region of the cutoff 
frequency, adding character to the sound. Excessively high 
settings can produce oscillation, causing the sound to distort.
NOTE
 
Making abrupt changes in the settings values may cause the 
sound to become distorted or overly loud. Carefully monitor 
volume levels while making the settings.
NOTE
 
With some Tones, the effect does not work as intended.
 
Changing the Bend Range 
(Bend Range)
 
This sets the amount of pitch change that will occur when 
you move the Pitch Bend lever (2 octaves).
 
Precise Modification of Chord 
Sonorities (Stretch Tune)
 
Changes the pitch using the ‘stretch tuning’ method typically 
used on acoustic pianos. This makes high-range sounds 
slightly higher in pitch, and low-range sounds slightly lower 
in pitch.
With a setting of OFF, the Patch’s tuning will be equal 
temperament. A setting of 3 will produce the greatest 
difference in the pitch of the low and high ranges.

Description
 
Attack Time
-63– +63
Higher values produce 
a milder attack; lower 
values produce a 
sharper attack.
Release Time
-63– +63
Higher values produce 
longer decay; set lower 
values for a clear-cut 
sound
Cutoff
-63–+63
Higher values brighten 
the sound; lower val-
ues make the sound 
seem darker.
Resonance
-63–+63
Higher value makes 
the special quality of 
the sound stronger; 
lower value reduce 
these characteristics.

This is the standard tuning 
curve.

(Stretch Tuning). It is suitable 
for performances such as piano 
solos.
