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.

Parameter Value 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.
