Chapter 4. Effect Settings
FLANGER
Produces a metallic resonance that rises and falls somewhat
like a jet airplane taking off or landing.
PHASER
Adds a phase-shifted sound to the original sound, producing
a swirling modulation.
CHORUS
Gives richness and spaciousness to the sound.
ENHANCER
Controls the overtone structure of the high frequencies,
adding sparkle and brightness to the sound.
PITCH SHIFT
Shifts the pitch of the original sound.
OVERDRIVE
Creates a soft distortion similar to that produced by vacuum
tube amplifiers.
DISTORTION
Produces a more intense distortion than Overdrive.
Parameter Value Description
Delay 0–15.0 (ms) Tone of the flanger
LFO Rate 1–128 Frequency of modulation
Depth 0–127 Depth of modulation
Feedback -98–98 (%) Amount of the flanger
sound that is fed back into
the effect (minus: inverts
the phase)
Phase 0–180 Spatial spread of the
sound
Parameter Value Description
Freq 100–8000 (Hz) Basic frequency at which
the sound will be modu-
lated
LFO Rate 1–128 Frequency of modulation
Depth 0–127 Depth of modulation
Resonance 0–127 Amount of feedback
Parameter Value Description
Delay 8.0–30.0 (ms) Tone of the chorus
LFO Rate 1–128 Frequency of modulation
Depth 0–127 Depth of modulation
Phase 0–180 Spatial spread of the
sound
Parameter Value Description
Sens 0–127 Sensitivity of the enhancer
LF Level 0–127 Volume level of the low
frequency range of the di-
rect sound
Parameter Value Description
Mode 1–5 Setting a higher value re-
sults in a slower response,
but steadier pitch.
Delay 0–100.0 (ms) Time until the pitch-shift-
ed sound is heard
Coarse -24–12 Amount of pitch shift
(semitone steps)
Fine -100–100 Amount of pitch shift (2-
cent steps)
Feedback -98–98 (%) Amount of the pitch-shift-
ed sound that is fed back
into the effect (minus: in-
verts the phase)
Parameter Value Description
Drive 0–127 Amount of distortion
HF Level 0–127 Level of high frequency
range
LF Bypass OFF, ON Bypass for the low fre-
quency range
When this is set to
“OFF,” the low frequen-
cy range also has a dis-
tortion sound.
Expanse OFF, ON Adding the spatial spread
of the sound
Parameter Value Description
Gain 0–127 Amount of distortion
HF Level 0–127 Level of high frequency
range
LF Bypass OFF, ON Bypass for the low fre-
quency range
When this is set to
“OFF,” the low frequen-
cy range also has a dis-
tortion sound.
Expanse OFF, ON Adding the spatial spread
of the sound
