Selects the number of stages that the phaser eect uses.
4 STAGE
A four-phase eect. A light phaser eect
is obtained.
8 STAGE
An eight-phase eect. This is the most
common phaser eect.
12 STAGE
A twelve-phase eect. A deep phase
eect is obtained.
BI-PHASE
A phaser with two phase-shift circuits
connected in series.
RATE #
0–100, BPM
–

DEPTH # 0–100 Adjusts the richness of the eect.
RESONANCE # 0–100 Adjusts the intensity of the eect.
LEVEL 0–100 Adjusts the volume level of the eect.
07: FLANGER
Parameter Value Description
RATE #
0–100,
BPM
–
Adjusts the speed of the eect.
DEPTH # 0–100 Adjusts the richness of the eect.
MANUAL # 0–100
Adjusts the modulation frequency of the
anger eect.
RESONANCE # 0–100 Adjusts the intensity of the eect.

12: DELAY
Parameter Value Description
TYPE
Use this to choose the type of delay.
SINGLE A simple monaural delay.
PAN
Provides a tap delay eect that divides the
delay time between the left and right channels.
STEREO
The direct sound is output from the left
channel, and the eect sound is output from
the right channel.
REVERSE Produces the eect of playback in reverse.
ANALOG Produces a mild analog delay sound.
TAPE
Provides the characteristic wavering sound of
a tape echo.
MODULATE
A delay with a pleasant amount of modulation
added.
HICUT
Produces a warm-sounding delay with the high
frequencies attenuated.
TIME #
1–3400 msec,
BPM
–
Adjusts the delay time.
FEEDBACK # 0–100 Adjusts the number of repetitions for the delay.
EFFECT LEVEL 0–120
Adjusts the volume level of the eect.
When TYPE is set to “REVERSE,” this adjusts the
balance of direct and eect sound.
13: CHORUS
Parameter Value Description
TYPE
Use this to choose the type of chorus.
MONO
This chorus eect outputs the same sound from
the left and right channels.
STEREO 1
A stereo chorus eect that adds dierent
chorus sounds to the left and right channels.
STEREO 2
This stereo chorus uses spatial synthesis, with
the direct sound output in the left channel and
the eect sound output in the right channel.
MONO MILD
Features a more suppressed high end than
MONO.
STEREO 1
MILD
Features a more suppressed high end than
STEREO 1.
STEREO 2
MILD
Features a more suppressed high end than
STEREO 2.
RATE #
0–100,
BPM
