181 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” set-
tings.
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 fil-
ter 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 temporar-
ily.
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
One cycle of LFO sweep is obtained by multiplying the length
of a note (
… ) (selected for “Base Note”, in relation to the
tempo specified in (“BPM”, or the MIDI Clock tempo if “BPM”
is set to
MIDI ) by the number specified in the Times parame-
ter.
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 spe ‐
cial effect 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” parameter
sets the original triangle waveform speed. Changing the “LFO
Step Freq” parameter enables you to adjust the width of the
steps.
