Resonance modulation
The effect of resonance
Low Pass
Level
Low resonance value
AMS (Alternate Modulation Source)
Selects the source that will control the "Resonance"
level. See "AMS (Alternate Modulation Source) list" on
page 124.
Intensity (AMS Intensity)
This parameter specifies the depth and direction of the
effect that "AMS (Alternate Modulation Source)" will
have on the resonance level specified by "Resonance
A".
For example if Velocity has been selected, changes in
keyboard velocity will affect the resonance.
With positive (+) values, the resonance will increase as
you play more strongly, and as you play more softly
the resonance will approach the level specified by the
"Resonance" setting.
With negative (–) values, the resonance will decrease as
you play more strongly, and as you play more softly
the resonance will approach the level specified by the
"Resonance" setting.
The resonance level is determined by adding the "Res-
onance" and "Intensity (AMS Intensity)" values.
-99...+99 Parameter value.
Filter B
Frequency B (Cutoff Frequency B)
This parameter specifies the cutoff frequency of filter B.
This parameter will be displayed when "Filter Type" is
set to Low Pass & High Pass.
High Pass
Level
12dB/oct
00...99 Cutoff frequency value.
PAGE 8 - FILTER MODULATION
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).
High resonance value
This filter cuts the low-frequency range that
lies below the cutoff frequency. By cutting
the lower overtones, it lightens the tone.
Frequency
Selected
Use this parameter to select an oscillator to put in edit.
Alternatively, you can select oscillators using the F-1–F-
4 buttons.
Filter keyboard tracking
Tracking Low/High
These settings specify keyboard tracking for the cutoff
frequency of the filter for the selected oscillator. The
way in which the cutoff frequency is affected by the
keyboard location you play can be specified by the
"Tracking Low", "Tracking High", "Ramp Low" and
"Ramp High" parameters.
C–1...G9 Lowest/Highest note in the range.
Tracking Low
Keyboard tracking will apply to the range below the
specified note number.
Tracking High
Keyboard tracking will apply to the range above the
specified note number.
Ramp
This parameter specifies the angle of keyboard tracking.
-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
Ramp Low
Ramp High
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 location (pitch). This
means that the oscillation that occurs when you
increase the "Resonance A" will correspond to the key-
board location.
If you set "Ramp Low" to +43 and "Ramp High" to –43,
the cutoff frequency will not be affected by keyboard
location. Use this setting when you do not want the
cutoff frequency to change for each note.
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).
