Filter Modulation, Resonance modulation, Filter B

Resonance modulation

The effect of resonance

Low Pass

Level

Low resonance value High resonance value

AMS (Alternate Modulation Source)

Selects the source that will control the “Resonance” level. See “AMS (Alternate Modulation Source) list” on page 123.

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 key- board 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 “Resonance” 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

This filter cuts the low-frequency range that lies below the cutoff frequency. By cutting the lower overtones, it lightens the tone.

12dB/oct

Frequency

00…99 Cutoff frequency value.

PAGE 8 - FILTER MODULATION

These settings let you apply modulation to the cutoff fre- quency (“Frequency”) of the ﬁlter for the selected oscillator to modify the tone.

Selected: Osc1

Tracking Low: B 3

Tracking High: F 5

Ramp Low:

+48

When “Filter Type” is Low Pass Resonance, parameters for ﬁlter B will not be editable (greyed out).

Selected

Use this parameter to select an oscillator to put in edit. Alter- natively, you can select oscillators using the F1-F4 buttons.

Filter keyboard tracking

Tracking Low/High

These settings specify keyboard tracking for the cutoff fre- quency of the ﬁlter for the selected oscillator. The way in which the cutoff frequency is affected by the keyboard loca- tion you play can be speciﬁed by the “Tracking Low”, “Track- ing High”, “Ramp Low” and “Ramp High” parameters.

C–1…G9Lowest/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			High Ramp=+99
			High Ramp=+62
			High Ramp=+62
			High Ramp=0
Low Ramp=+99			High Ramp=–43
Low Ramp=+99
Low Ramp=+43			High Ramp=–99
Low Ramp=+43
Low Ramp=0
Low Ramp=–62			Key
Low Ramp=–62	Low Key		Key
	Low Key	High 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 key- board location (pitch). This means that the oscillation that occurs when you increase the “Resonance A” will correspond to the keyboard 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 key- board 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).
