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 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
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 Sync=Off, the LFO speed uses the LFO
Frequency parameter setting. When 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
parameter.

f: LFO Type
f: CmnLFO Offset [deg]
If Type is set to Common 1 or Common 2, modulation will
be applied using the Common FX LFO rather than the LFO
within the effect itself. Since this lets you use the same LFO
for multiple effects, it's useful when you want to apply
various types of modulation in synchronization.
CmnLFO Offset specifies the phase difference relative to the
Common FX LFO. For more information, please see
"Common FX LFOs" on page 273.
