EFFECT

MODULATE
Parameter Value Explanation
MOD RATE 0–100
Adjusts the modulation rate of the delay
sound.
MOD DEPTH 0–100
Adjusts the modulation depth of the delay
sound.
CHORUS
In this eect, a slightly detuned sound is added to the original sound to
add depth and breadth.
Parameter Value Explanation
CHORUS ON/
OFF
OFF, ON Turns this eect on/o.
MODE
Selection for the chorus mode.
MONO
This chorus eect outputs the same sound
from both L channel and R channel.
STEREO 1
This is a stereo chorus eect that adds
dierent chorus sounds to L channel and R
channel.
STEREO 2
This stereo chorus uses spatial synthesis, with
the direct sound output in the L channel and
the eect sound output in the R channel.
RATE
0–100,
BPM
–
Adjusts the rate of the chorus eect.
* When set to BPM, the value of each
parameter will be set according to the
value of the “MASTER BPM” specied for
each patch. This makes it easier to achieve
eect sound settings that match the tempo
of the song.
* If, due to the tempo, the time is longer than
the range of allowable settings, it is then
synchronized to a period either 1/2 or 1/4
of that time.
DEPTH 0–100
Adjusts the depth of the chorus eect.
* To use it for doubling eect, set the value
to 0.
EFFECT LEVEL 0–100 Adjusts the volume of the eect sound.
PRE DELAY 0.0 ms–40.0 ms
Adjusts the time needed for the eect sound
to be output after the direct sound has been
output. By setting a longer pre delay time,
you can obtain an eect that sounds like
more than one sound is being played at the
same time (doubling eect).
LOW CUT FLAT, 20 Hz–800 Hz
This sets the frequency at which the low
cut lter begins to take eect. When “Flat” is
selected, the low cut lter will have no eect.
HIGH CUT
630 Hz–12.5 kHz,
FLAT
This sets the frequency at which the high
cut lter begins to take eect. When “Flat”
is selected, the high cut lter will have no
eect.
REVERB
This eect adds reverberation to the sound.
Parameter Value Explanation
REVERB ON/
OFF
OFF, ON Turns this eect on/o.
TYPE
This selects the reverb type. Various dierent simulations of space
are oered.
AMBIENC
(AMBIENCE)
Simulates an ambience mic (o-mic, placed
at a distance from the sound source) used in
recording and other applications. Rather than
emphasizing the reverberation, this reverb
is used to produce a sense of openness and
depth.
ROOM
Simulates the reverberation in a small room.
Provides warm reverberations.
HALL 1
Simulates the reverberation in a concert hall.
Provides clear and spacious reverberations.
HALL 2
Simulates the reverberation in a concert hall.
Provides mild reverberations.
PLATE
Simulates plate reverberation (a reverb unit
that uses the vibration of a metallic plate).
Provides a metallic sound with a distinct
upper range.
SPRING
This simulates the sound of a guitar amp’s
built-in spring reverb.
MOD (MODULATE)
This reverb adds the wavering sound found
in hall reverb to provide an extremely
pleasant reverb sound.
REV TIME 0.1 s–10.0 s Adjusts the length (time) of reverberation.
PRE DELAY 0 ms–500 ms
Adjusts the time until the reverb sound
appears.
EFFECT LEVEL 0–100 Adjusts the volume of the reverb sound.
LOW CUT FLAT, 20 Hz–800 Hz
This sets the frequency at which the low
cut lter begins to take eect. When “Flat” is
selected, the low cut lter will have no eect.
HIGH CUT
630 Hz–12.5 kHz,
FLAT
This sets the frequency at which the high
cut lter begins to take eect. When “Flat”
is selected, the high cut lter will have no
eect.
DENSITY 0–10 Adjusts the density of the reverb sound.
DIRECT MIX 0–100 Adjusts the volume of the direct sound.
SPRING SENS
(TYPE =
SPRING only)
0–100
Adjusts the sensitivity of the spring eect.
When the value is set higher, the eect is
obtained even with a weak picking.
