Effects

Modulation and Pitch Shift (Mod./P.Shift)

Advanced

a: Control Mode

f: Voice 1: Resonance

h: Voice 2: Resonance

This parameter determines the resonance intensity.

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

sets the intensity of resonance. If the “Resonance” 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 positive and neg-

ative values, causing resonance to occur between specified

pitches an octave apart in turn.

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

the dynamic modulation source. If JS X or Ribbon 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 res-

onate at a pitch an oct ave below (Resonance has a neg ative

value).

f: Voice 1: Pitch

f: Fine [cents]

h: Voice 2: Pitch

h: Fine [cents]

The Pitch parameter specifies the pitch of resonance by note

name. The “Fine” parameter allows for fine adjustment in steps

of cents.

g: High Damp [%]

i: High Damp [%]

This sets the amount of damping amount for the hig h frequen-

cies of the resonant sound. Lower values create a metallic sound

with a higher range of harmonics.

49: Doppler

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

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

lance. 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 repeat-

edly. 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 spe cified in the “Src”

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

eter, the Doppler effect will not be created, and no effect sound

will be output.
