Effects
Filter/Dynamic
a: Frequency Bottom, a: Frequency Top
The sweep width and direction of the wah filter are deter-
mined by the “Frequency Top” and “Frequency Bottom”
settings.
The sweep width and direction of the wah filter are deter-
mined by the “Frequency Top” and “Frequency Bottom”
settings.
b: Sweep Mode
This parameter changes the wah control mode. Setting
“Sweep Mode” to Auto will select an auto-wah that
sweeps according to envelope changes in the input signal
level. Auto-wah is frequently used for funk guitar parts
and clav sounds.
When “Sweep Mode” is set to D-mod, you can control the
filter directly via the modulation source in the same way
as a wah pedal.
When “Sweep Mode” is set to LFO, the effect uses LFO to
sweep in cycle.
c: Envelope Sens (Envelope Sensitivity)
This parameter sets the sensitivity of auto-wah. Increase
the value if the input signal is too low to sweep. Reduce
the value if the input signal is so high that the filter is
stopped temporarily.
c: Envelope Shape
This parameter determines the sweep curve for auto-wah.

d: LFO Frequency [Hz], e: BPM/MIDI Sync
When “BPM/MIDI Sync”=Off, the LFO speed uses the LFO
Frequency parameter setting. When “BPM/MIDI
Sync”=On, the LFO speed follows the “BPM”, “Base
Note”, and “Times” settings.
e: BPM, e: Base Note, e: Times

010: Random Filt
(Stereo Random Filter)
This stereo band pass filter uses a step-shape waveform and
random LFO for modulation. You can create a special effect
from filter oscillation.

from filter oscillation.
a: LFO Waveform, c: LFO Frequency [Hz],
d: LFO Step Freq (Frequency) [Hz]
When “LFO Waveform” is set to Step-Tri, LFO is a step-
shape, triangle waveform. The “LFO Frequency” parame-
ter sets the original triangle waveform speed. Changing
the “LFO Step Freq” parameter enables you to adjust the
width of the steps.
d: LFO Step Freq (Frequency) [Hz]
When “LFO Waveform” is set to Step-Tri, LFO is a step-
shape, triangle waveform. The “LFO Frequency” parame-
ter sets the original triangle waveform speed. Changing
the “LFO Step Freq” parameter enables you to adjust the
width of the steps.
