Filter: Filter Mod

Filter: Filter Mod
These settings let you apply modulation to the cutoff frequency
("Frequency") of the filter for the selected oscillator to modify
the tone.
When "Filter Type" is Low Pass Resonance, parameters for filter
B will not be editable (greyed out).
Keyboard Tracking
Key Low/High
These settings specify keyboard tracking for the cutoff frequency
of the filter for the selected oscillator. The way in which the cut-
off frequency is affected by the keyboard location you play can
be specified by the "Key Low", "Key High", "Ramp Low" and
"Ramp High" parameters.
Keyboard tracking will apply to the range below the specified
Low note number, and above the specified High note number.
C–1...G9 Lowest/Highest note in the range.
Ramp Low/High
These parameter specifies the angle of keyboard tracking.
If "Intensity to A" and "Intensity to B" are set to +50, "Ramp
Low" is set to –62 and "Ramp High" is set to +62, the angle of the
change in cutoff frequency will correspond to the keyboard loca-
tion (pitch). This means that the oscillation that occurs when
you increase the "Resonance (Resonance A)" will correspond to
the keyboard location.
If you set "Ramp Low" to +43 and "Ramp High" to –43, the cut-
off frequency will not be affected by keyboard location. Use this
setting when you do not want the cutoff frequency to change for
each note.
-99...+99 Angle value.
Here is how cutoff frequency is affected by keyboard location
and the Ramp setting ("Intensity to A" and "Intensity to B" =
+50):
Cutoff frequency
Low Ramp=+99
Low Ramp=+43
Low Ramp=0
Low Ramp=–62
Low Key
Low Ramp=–99
High Ramp=+99
High Ramp=+62
High Ramp=0
High Ramp=–43
High Ramp=–99

Tracking to A/B
These parameters specify the note numbers at which keyboard
tracking will begin to apply, and set the "Intensity to A" and
"Intensity to B" parameters to specify the depth and direction of
the change applied to filters A and B.
For the range of notes between "Key Low" and "Key High", the
cutoff frequency will change according to the keyboard location
(pitch).

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 EG (as set on "Filter: Filter EG") to control the filter A
cutoff frequency.
With positive (+) values, playing more strongly will cause the fil-
ter EG to produce greater changes in cutoff frequency. With neg-
ative (–) values, playing more strongly will also cause the filter
EG to produce greater changes in cutoff frequency, but with the
polarity of the EG inverted.
99...+99 Value of the Velocity to A parameter.
Velocity to B
This parameter specifies the depth and direction of the effect
that velocity will have on the time-varying changes created by
the filter EG to control the filter B cutoff frequency (see "Veloc-
ity to A").
99...+99 Value of the Velocity to B parameter.
Int to A (Intensity to A)
Specifies the depth and direction of the effect that the time-vary-
ing changes created by the filter 1 EG will have on the filter A
cutoff frequency.
With positive (+) settings, the sound will become brighter when
the EG levels set by Filter EG "Level" and "Time" parameters 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 EG "Level" and "Time" parameters are
in the "+" area, and brighter when they are in the "–" area.
-99...+99 Parameter value.
Int to B (Intensity to B)
Specifies the depth and direction of the effect that the time-vary-
ing changes created by the filter EG will have on the filter B cut-
off frequency (see "Int to A (Intensity to A)").
-99...+99 Parameter value.
