3–2: Filter1 Mod.
Here you can make settings to specify how keyboard track-
ing, controllers, and filter 1 EG intensity will control the Fil-
ter 1 cutoff frequency "Frequency" (A/B Frequency) to
modify the tone.
When "Filter Type" (3–1a) is Low Pass Resonance, parame-
ters for filter B will not be displayed.

3–2a: Keyboard Track
These settings specify keyboard tracking for the cutoff fre-
quency of filter 1.
The way in which the cutoff frequency is affected by the
position of the key you play (note number) can be specified
by the "Key Low (KBDTrk Key Low)," "Key High (KBDTrk
Key High)," "Ramp Low (KBDTrk Ramp Low)" and "Ramp
High (KBDTrk Ramp High)" parameters.
Key:
Specifies the note number at which keyboard tracking will
begin to be applied, and set the "Intensity to A (KBDTrk Int.
to A)" and "Intensity to B (KBDTrk Int. to B)" parameters to
specify the depth and direction of the change applied to fil-
ter 1 A and B.
For the range of notes between "Key Low (KBDTrk Key
Low)" and "Key High (KBDTrk Key High)," the cutoff fre-
quency will change according to the key position (pitch).
Note numbers can also be entered by holding down the
[ENTER] key while you press a note on the keyboard.
Key Low (KBDTrk Key Low)
Keyboard tracking will apply to the range below the speci-
fied note number.
Key High (KBDTrk Key High)
Keyboard tracking will apply to the range above the speci-
fied note number.
Ramp (Ramp Setting):
Specifies the angle of keyboard tracking.
Ramp Low (KBDTrk Ramp Low)
Ramp High (KBDTrk Ramp High)
If "Intensity to A (KBDTrk Int. to A)" and "Intensity to B
(KBDTrk Int. to B)" are set to +50, "Ramp Low (KBDTrk
Ramp Low)" is set to –62 and "Ramp High (KBDTrk Ramp
High)" is set to +62, the angle of the change in cutoff fre-
quency will correspond to the keyboard location (pitch).
This means that the oscillation that occurs when you
increase the "Resonance (A Resonance)" (3–1b) will corre-
spond to the keyboard location.
If you set "Ramp Low (KBDTrk Ramp Low)" to +43 and
"Ramp High (KBDTrk Ramp High)" to –43, the cutoff fre-
quency will not be affected by keyboard location. Use this
setting when you do not want the cutoff frequency to
change for each note.
How cutoff frequency is affected by keyboard location and the Ramp
setting
("Intensity to A" and "Intensity to B" = +50)
3–2
Intensity to A (KBDTrk Int. to A)
Specifies the depth and direction of the effect that the key-
board tracking specified by "Key Low (KBDTrk Key Low),"
"Key High (KBDTrk Key High)," "Ramp Low (KBDTrk
Ramp Low)" and "Ramp High (KBDTrk Ramp High)" will
have on filter 1A.
With positive (+) values, the effect will be in the direction
specified by keyboard tracking, and with negative (–) val-
ues the effect will be in the opposite direction.
Intensity to B (KBDTrk Int. to B)
Specifies the depth and direction of the effect that keyboard
tracking will have on filter 1B (☞"Intensity to A (KBDTrk
Int. to A)").
3–2b: Filter EG
Velocity to A
This parameter specifies the depth and direction of the effect
that velocity will have on the time-varying changes created
by the filter 1 EG (as set by "Filter 1 EG" 3–4) to control the
filter 1A cutoff frequency.
With positive (+) values, playing more strongly will cause
the filter 1 EG to produce greater changes in cutoff fre-
quency. With negative (–) values, playing more strongly will
also cause the filter 1 EG to produce greater changes in cut-
off frequency, but with the polarity of the EG inverted.
Velocity to B
This parameter specifies the depth and direction of the effect
that velocity will have on the time-varying changes created
[C–1...G9]
by the filter 1 EG to control the filter 1B cutoff frequency (☞
"Velocity to A").

[–99...+99]
Intensity to A
Specifies the depth and direction of the effect that the time-
varying changes created by the filter 1 EG will have on the
filter 1A cutoff frequency.
With positive (+) settings, the sound will become brighter
when the EG levels set by Filter 1 EG Level and Time parame-
ters (3–4a) are in the "+" area, and darker when they are in
the "–" area.
With negative (–) settings, the sound will become darker
when the EG levels set by Filter 1 EG "Level" and "Time"
parameters (3–4a) are in the "+" area, and brighter when
they are in the "–" area.
