10: St. Wah/Auto Wah
(Stereo Wah/Auto Wah)
This stereo wah effect allows you to create sounds from vintage
wah pedal simulation to auto-wah simulation, and much
broader range settings.

The sweep width and direction of the wah filter are determined
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 fre-
quently 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
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.
Level
value = 0...+100
value = 0...–100
d: LFO Frequency [Hz]
e: MIDI Sync
When "MIDI/Tempo Sync"=Off, the LFO speed uses the LFO
Frequency parameter setting. When "MIDI/Tempo Sync"=On,
the LFO speed follows the "BPM", "Base Note", and "Times" set-
tings.
e: BPM
e: Base Note
e: Times
One cycle of LFO sweep is obtained by multiplying the length of
a note (r...w) (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 parameter.
