c: 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.

d: 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.

e:Envelope Shape This parameter determines the sweep curve for auto-wah.
