Eect Settings (EFFECT)
Parameter Value Description
POLARITY
Selects whether the left and right phase of the modulation
will be the same or the opposite.
INVERSE
The left and right phase will be
opposite. When using a mono
source, this spreads the sound.
SYNCHRO
The left and right phase will
be the same. Select this when
inputting a stereo source.
RESONANCE # 0–100 Adjusts the amount of feedback.
CROSS
FEEDBACK
-98–+98%
Adjusts the proportion of the
phaser sound that is fed back
into the eect. Negative (-)
settings will invert the phase.
STEP RATE #
0–100, BPM
Adjusts the rate of the stepwise
change in the phaser eect.
MIX 0–100
Adjusts the level of the phase-
shifted sound.
LOW GAIN -15–+15 dB
Adjusts the gain of the low
range.
HIGH GAIN -15–+15 dB
Adjusts the gain of the high
range.
LEVEL 0–100 Adjusts the output volume.
05: RING MODULATOR
This is an eect that applies amplitude modulation (AM) to the input signal, producing
bell-like sounds. You can also change the modulation frequency in response to
changes in the volume of the sound sent into the eect.

Parameter Value Description
FREQUENCY # 0–127
Adjusts the frequency at which
modulation is applied.
SENS # 0–100
Adjusts the amount of frequency
modulation applied.
POLARITY
Determines whether the frequency modulation moves
towards higher frequencies or lower frequencies.
UP Higher frequencies
DOWN Lower frequencies
LOW GAIN -15–+15 dB
Adjusts the gain of the low
frequency range.
HIGH GAIN -15–+15 dB
Adjusts the gain of the high
frequency range.
BALANCE # D100:0W–D0:100W
Adjusts the volume balance
between the direct sound (D)
and the eect sound (W).
LEVEL 0–100 Adjusts the output volume.
06: TREMOLO
Cyclically alters the volume.

RATE #
0–100, BPM
Adjusts the frequency of the
change.
DEPTH # 0–100 Adjusts the depth of the eect.
LOW GAIN -15–+15 dB Adjusts the gain of the low range.
HIGH GAIN -15–+15 dB
Adjusts the gain of the high
range.
