Chapter 4 The Effects Explained

■ VIB: Vibrato
The vibrato effect is created by slightly modulating the pitch.
Parameter Value
Rate 0–100, BPM –BPM
Depth 0–100
Trigger Off, On
Rise Time 0–100
Rate
This adjusts the period of the vibrato.
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
] to
display the Master BPM settings screen.
Depth
This adjusts the depth of the vibrato.
Trigger
The vibrato is turned on and off with the foot switch.
* This parameter is premised on the trigger being turned on
with the foot switch only when producing the vibrato effect.
Use this by assigning it to the CTL pedal or other control (p.
46).
Rise Time
This adjusts the time from the moment the trigger is turned
on until the set vibrato effect is obtained.
■ HMN: Humanizer
This effect changes the sound of the bass guitar into sounds
resembling the human voice. Applying this after distorting
the sound with OD/DIST or other such effect strengthens the
effect.
For more on the order in which effects are connected, refer to
p. 22.
Parameter Value
Mode 1 Shot, Auto, Random
Vowel1 a, e, i, o, u Mode= 1 Shot, Auto
Vowel2 a, e, i, o, u Mode= 1 Shot, Auto
Trigger On, Off
Sensitivity 0–100
Rate 0–100, BPM –BPM
Depth 0–100
Manual 0–100
Level 0–100
Mode
This sets the mode used to switch the vowels.
1 Shot:
The tone changes from Vowel 1 to Vowel 2 one time only as
the strings are played. The time required for the change is
adjusted with the Rate setting.
Auto:
The change in tone between the two vowels (Vowel 1 and
Vowel 2) is repeated.
Random:
Five vowels (a, e, i, o, u) are switched randomly.
Vowel 1
(with 1 Shot and Auto)
Selects the first vowel.
fig.04-05
Vowel 2
(with 1 Shot and Auto)
Selects the second vowel.
Trigger
(with Auto and Random)
This selects whether or not the tone changes start
simultaneously as the strings are played.
It could be said that when “1 Shot” is selected, the trigger is
always on.
Sens
This adjusts the trigger sensitivity. With the sensitivity at a
low setting, the trigger is activated only when greater force is
used to play the strings, but not when the strings are played
softly.
Rate
This adjusts the cycle over which the two vowels change.
* When set to BPM, the value of each parameter is set according
to the value of the Master BPM (p. 44) specified for each patch.
This makes it easy to achieve effect sound settings that match
the tempo of the song (synchronizing the cycle to one-half or
one-fourth of the BPM when the set cycle rate is increased).
When setting to the BPM, press PARAMETER [
] to
display the Master BPM settings screen.
Depth
Adjusts the depth of the effect. The transition between
vowels becomes clearer as the value is increased.
