Auto Wah in Fuzz-Wah effect in Logic Pro for iPad

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.

Auto Wah parameters

On/Off button: Turn the Auto Wah effect on or off.
Wah Mode 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 Relative Q(uality) setting. Relative Q determines the resonant characteristics. Low Relative Q values affect a wider frequency range, resulting in softer resonances. High Relative 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 Relative Q(uality) Factor setting.
- Opto Wah 2: This setting mimics the sound of a distortion wah pedal with a constant Relative Q(uality) 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.
Auto Wah Depth knob and field: Set the intensity of the Auto Wah effect. When set to 0, the automatic wah feature is disabled.
Relative Q knob and field: Adjust the main filter peak, resulting in a sharper or softer wah sweep.
Auto Wah Attack knob and field: Set the time it takes for the wah filter to fully open.
Auto Wah Release knob and field: Set the time it takes for the wah filter to close.
Wah Level knob and field: Set the amount of the wah-filtered signal.
Pedal Position knob and field: Set a virtual pedal position.
Pedal Start/Pedal Range End sliders and field: Set the maximum and minimum values of the sweep range. You can sweep the wah filter range with the Pedal Position knob or with a MIDI pedal.
