DEPTH
RATE
MIX
0 – 50
1 – 50
0 – 50
Chorus effect with clear sound.
Adjusts the effect depth.
Adjusts the modulation rate.
Adjusts the effect sound mixing ratio.
TYPE 2
CE-CHO
DEPTH
TONE
MIX
(CE Chorus)
(Chorus)
0 – 50
0 – 10
0 – 50
Simulates a vintage analog chorus characterized by warm, full-bodied sound.
Adjusts the effect depth.
Adjusts the effect sound character.
Adjusts the effect sound mixing ratio.
TYPE 3
FLANGE
DEPTH
RATE
RESO
(Flanger)
0 – 50
1 – 50
-15 – 15
This effect produces a unique, undulating sound.

values result in effect sound with reversed
phase.
TYPE 4
VIBRAT
DEPTH
RATE
BAL
(Vibrato)
(Step)
0 – 50
1 – 50
0 – 50
This is a vibrato effect that periodically varies the pitch.

Adjusts the mixing balance between
effect sound and original sound. Higher
values result in stronger effect sound.
TYPE 5
STEP
DEPTH
RATE
FB
0 – 50
1 – 50
0 – 50
This is a special effect with step-like filter characteristics. The cutoff is varied in discrete steps at a constant rate,
resulting in a sample-and-hold type effect.
Adjusts the effect depth.
Adjusts the modulation rate.
Adjusts the feedback amount.
TYPE 6
TREMOL
DEPTH
RATE
CLIP
(Tremolo)
0 – 50
1 – 50
0 – 10
This effect periodically varies the level of the sound.
Adjusts the effect depth.
Adjusts the modulation rate.
Higher values result in clipped
modulation signal waveform, which
emphasizes the modulation.
