Chapter 4 Introduction to Effects and Parameters
Section 4
Wave
This selects a wave type that is the source of the guitar
synthesizer.
Square:
The unit detects the pitch and attack information from the
input guitar sound, then send the square waveform
() from the internal sound generator.
Saw:
The unit detects the pitch and attack information from the
input guitar sound, then send the saw waveform ( )
from the internal sound generator.
Brass:
The unit directly processes the input guitar sound and
creates a guitar synthesizer sound. It gives a quick sound rise
and send the sound with a sharp edge.
Bow:
The unit directly processes the input guitar sound and
creates a guitar synthesizer sound. It outputs a soft sound
without attack.
Chromatic
This switches on or off the chromatic function. When it is on,
the pitch change of the synthesizer sound is in semitone
steps. This does not respond to pitch changes less than a
semitone, such as what might be obtained with bending or
vibrato. Thus, this is effectively used for realistically playing
musical instruments whose pitch will change in steps greater
than a semitone, such as a keyboard.
* Use this parameter when “Square” or “Saw” is selected for
wave.
Octave Shift
This allows you to shift the pitch of the internal sound
module in an octave step from the guitar sound.
* This parameter should be set when “Square” or “Saw” is
selected for the wave.
PWM Rate
(Pulse Wise Modulation Rate)
This gives breadth or fatness to the sound by applying
modulation to the waveform (only to Square) in the internal
sound module. A higher value will quicken the rate of the
modulation.
* This parameter should be set only when “Square” is selected
for the wave.
PWM Depth
(Pulse Wise Modulation Depth)
This adjusts the depth of the PWM. When it is set to “0,” no
PWM effect is obtained.
* This parameter should be set only when “Square” is selected
for the wave.
Cutoff Freq (Cutoff Frequency)
This adjusts the frequency where the harmonics contents of
the sound are cut off.
Resonance
This adjusts how much of the harmonics contents around the
cutoff frequency should be emphasized.
FLT.Sens (Filter Sensitivity)
This adjusts the sensitivity of the filter. When it is set to a
lower value, the filter is affected only with stronger picking.
When it is set higher, the filter changes even with weaker
picking. When it is set to “0,” the depth of the filter will be
the same no matter how the picking strength may be.
FLT.Decay (Filter Decay)
This sets the time needed for the filter to finish its sweep.
FLT.Depth (Filter Depth)
This adjusts the depth of the filter. When the value is higher,
the filter will change more drastically. The polarity of the
filter will be opposite with “+” and “-.”
Attack
This adjusts the time needed for a synthesizer sound to reach
its maximum. When it is set to a lower value, the sound will
rise quickly. When it is set higher, the sound will rise slowly.
When it is set to “Decay,” the sound will rise quickly and
turn to a Release status regardless of the input of the guitar
sound.
* When “Brass” or “Bow” is selected for the wave, the attack
time will not be quicker from a certain level even if the attack is
set to “Decay” or “0.”
Release
This determines the time needed for the synthesizer sound to
reach zero from the moment the input of the guitar sound is
completed.
* When “Brass” or “Bow” is selected for the wave, the guitar
signal itself is processed. That is, the synthesizer sound will go
down when the guitar signal goes down no matter how long
the release may be set.
