Effect parameters |733
When "Control Mode" = Manual, the "Resonance" parameter sets the inten-
sity of resonance. If the "Resonance" parameter has a negative value, har-
monics 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 negative values, causing reso-
nance 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 resonate at a pitch an octave below (Reso-
nance has a negative 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 high frequencies of the
resonant sound. Lower values create a metallic sound with a higher range
of harmonics.
