Parameter Value Description
Mode 4, 8 stage Number of stages in the phaser
Polarity INVERSE, Selects whether the left and right
SYNCHRO phase of the modulation are the
same or opposite each other.
Rate #2 0.05–10.00 Frequency of modulation
Hz, note
Depth 0–127 Depth of modulation
Manual #1 0–127 Adjusts the basic frequency from
which the sound is modulated.
Resonance 0–127 Amount of feedback
Cross -98– +98 % Adjusts the amount of the phaser
Feedback sound that's fed back into the effect.
Negative (-) settings invert the phase.
Mix 0–127 Level of the phase-shifted sound
Low Gain -15– +15 dB Gain of the low frequency range
High Gain -15– +15 dB Gain of the high frequency range
Level 0–127 Output level

12:STEP PHASER

With the Step effects, you can also make stepped changes in the pitch
of sounds to which the Phaser effect is applied.

INVERSE: The left and right
phase are opposite. When using a
mono source, this spreads the
sound in stereo.
SYNCHRO: The left and right
phase are the same. Select this
when working with a stereo source.

13: RING MODULATOR
This is an effect 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 effect.

Parameter Value Description
Frequency 0–127 Adjusts the frequency at which
#1 modulation is applied.
Sens 0–127 Adjusts the amount of frequency
modulation applied.
Polarity UP, Determines whether the frequency
DOWN modulation moves towards higher
frequencies (UP) or lower frequen-
cies (DOWN).
Low Gain -15– +15 dB Gain of the low frequency range
High Gain -15– +15 dB Gain of the high frequency range
Balance #2 D100:0W– Volume balance between the direct
D0:100W sound (D) and the effect sound (W)
Level 0–127 Output level

14: TREMOLO

Cyclically modulates the volume to add tremolo to the sound.
