Effects

Pitch/Phase Mod.

a: Control Mode, e: Voice1: Resonance, h: Voice2:

Resonance

This parameter determines the resonance intensity.

When “Control Mode” = Manual, the “Resonance”

parameter sets the intensity of resonance. If the “Reso-

nance” parameter has a negative value, harmonics will be

changed, and resonance will occur at a pitch one octave

lower.

When “Control Mode” = LFO, the intensity of resonance

varies according to the LFO. The LFO sways between posi-

tive and negative values, causing resonance to occur

between speciﬁed pitches an octave apart in turn.

When “Control Mode” = D-mod, the resonance is con-

trolled by the dynamic modulation source. If JS X or Rib-

bon is assigned as the modulation source, the pitch an

octave higher and lower can be controlled, similar to

when LFO is selected for Control Mode.

a: LFO/D-mod Invert

When “Control Mode” = LFO or D-mod, the controlled

phase of either Voice 1 or 2 will be reversed. When the

resonance pitch is set for Voice 1 (Resonance has a positive

value), Voice 2 will resonate at a pitch an octave below

(Resonance has a negative value).

d: Voice1: Pitch, d: Fine [cent], g: Voice2: Pitch, g: Fine

[cent]

The Pitch parameter speciﬁes the pitch of resonance by

note name. The “Fine” parameter allows for ﬁne adjust-

ment in steps of cents.

e: High Damp [%], h: High Damp [%]

This parameter sets the damping amount of resonant

sound in the high range. Lower values will make a metal-

lic sound with a higher range of harmonics.

030: Doppler

This effect simulates the “Doppler effect” of a moving sound

with a changing pitch, similar to the siren of an passing

ambulance. Mixing the effect sound with the dry sound will

create a unique chorus effect.

a: LFO Mode, a: Src, b: LFO Sync

The “LFO Mode” parameter switches LFO operation

mode. When Loop is selected, the Doppler effect will be

created repeatedly. If “LFO Sync” is set to On, the LFO will

be reset when the modulation source speciﬁed with the

“Src” parameter is turned on.

When “LFO Mode” is set to 1-Shot, the Doppler effect is

created only once when the modulation source speciﬁed

in the “Src” ﬁeld is turned on. At this time if you do not

set the “Src” parameter, the Doppler effect will not be

created, and no effect sound will be output.

The effect is off when a value for the modulation source speci-

ﬁed for the “Src” parameter is smaller than 64, and the effect is

on when the value is 64 or higher. The Doppler effect is trig-

gered when the value changes from 63 or smaller to 64 or

higher.

e: Pitch Depth

With the Doppler effect, the pitch is raised when the

sound approaches, and the pitch is lowered when the

sound goes away. This parameter sets this pitch variation.

f: Pan Depth

This parameter sets the width of the stereo image of the

effect sound. With larger values, the sound seems to come

and go from much further away. With positive values, the

sound moves from left to right; with negative values, the

sound moves from right to left.
