• CutoffSens (Cutoff Sensitivity)
Determines the degree to which the notes (specifically,
their position or octave range) affect the Filter of the
selected element. A Center Key setting of C3 is used as the
basic setting by the Cutoff parameter.
A positive setting will lower the Cutoff frequency for
lower notes and raise it for higher notes. A negative setting
will have the opposite effect.
❏ Settings -200% ~ 0 ~ +200%
• CenterKey
This indicates that the central note for Cutoff Sensitivity
above is C3. At C3, the tone remains unchanged. For other
notes played, the Cutoff Frequency varies according to the
particular note and the Cutoff Sensitivity setting. Keep in
mind that this is for display purposes only; the value
cannot be changed.
•EGTimeSens (EG Time Sensitivity)
Determines the degree to which the notes (specifically,
their position or octave range) affect the Filter EG times of
the selected element.
The basic speed of change for the FEG is at the note
specified in the Center Key (next parameter).
A positive setting will cause slower changes for lower
notes and faster changes for higher notes. A negative
setting will have the opposite effect.
❏ Settings -64 ~ 0 ~ +63
• CenterKey
Determines the central note or pitch for the Key Follow
effect on Filter EG. Depending on the EG Time Sensitivity
parameter above, the further away from the Center Key the
keys are played, the more the time of the Filter EG deviates
from the norm. When the Center Key note is played, the
FEG behaves according to its actual settings. The Filter
change characteristics for other notes will vary in
proportion to the EG Time settings.
❏ Settings C -2 ~ G8
n You can also set the Center Key directly from the
keyboard, by holding down the [INFORMATION]
button and pressing the desired key. See “Basic
Operation” on page 75.
● [F3]-[SF5] Normal Element Filter Scaling
Filter Scaling controls the filter cutoff frequency
according to the positions of the notes on the
keyboard. You can divide the entire keyboard by
four break points, and assign different offset values
of Cutoff Frequency to them respectively.
• BREAK POINT 1 ~ 4
❏ Settings C -2 ~ G8
n You can also set the Break Point directly from the
Keyboard, by holding down the [INFORMATION]
button and pressing the desired key. See “Basic
Operation” on page 75.
• OFFSET 1 ~ 4
❏ Settings -128 ~ 0 ~ +127
The best way to understand Filter Scaling is by
example. For the settings shown in the example
display above, the basic Cutoff frequency value is
64, and the various Offset values at the selected
Break point settings change that basic value
accordingly. The specific changes to the Cutoff
frequency are shown in the diagram below. The
Cutoff frequency changes in a linear fashion
between successive Break Points as shown.
n BP1 to BP4 will be automatically be arranged in
ascending order across the keyboard.
n Regardless of the size of these Offsets, the
minimum and maximum Cutoff limits (values of 0
and 127, respectively) cannot be exceeded.
n Any note played below the BP1 note results in the
BP1 Level setting. Likewise, any note played above
the BP4 note results in the BP4 Level setting.
