These parameters determine the tone and behavior of the wah effect.
You can control the wah effect with the Auto Wah feature, which continually performs a filter sweep across the entire range. You can also control the wah sweep with MIDI foot pedals or other controllers.
On/off button: Turn the Auto Wah effect on or off.
Wah Type pop-up menu: Choose a Wah effect type.
Classic Wah: This setting mimics the sound of a popular wah pedal with a slight peak characteristic.
Retro Wah: This setting mimics the sound of a popular vintage wah pedal.
Modern Wah: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting. The Q determines the resonant characteristics. Low Q values affect a wider frequency range, resulting in softer resonances. High Q values affect a narrower frequency range, resulting in more pronounced emphasis.
Opto Wah 1: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting.
Opto Wah 2: This setting mimics the sound of a distortion wah pedal with a constant Q(uality) Factor setting.
Resonant LP: In this mode, the Wah works as a resonance-capable lowpass filter. At the minimum pedal position, only low frequencies can pass.
Resonant HP: In this mode, the Wah works as a resonance-capable highpass filter. At the maximum pedal position, only high frequencies can pass.
Peak: In this mode, the Wah works as a peak (bell) filter. Frequencies close to the cutoff frequency are emphasized.
Auto Gain button: Limit the output signal dynamic range. The wah effect can cause the output level to vary widely. Auto Gain compensates for this tendency and keeps the output signal within a more stable range.
Relative Q knob and field: Adjust the main filter peak, resulting in a sharper or softer wah sweep.
Wah Level knob and field: Set the amount of the wah-filtered signal.
Depth knob and field: Set the depth of the Auto Wah effect. When set to 0, the automatic wah feature is disabled.
Attack knob and field: Set the time it takes for the wah filter to fully open.
Release knob and field: Set the time it takes for the wah filter to close.
Range slider and field: Sweep the wah filter with a MIDI pedal. The two smaller sliders set the maximum and minimum values of the sweep range.
