Auto Wah
Turning up the speed control in the top left corner of the Wah section
activates Auto Wah, a Wah that automatically modulates at the speed
you set. The foot pedal now controls the center frequency of the Wah.
Set the Auto Wah rate by moving the speed control. The following ta-
ble gives some examples of how long one filter movement or Wah will
take at different speed settings:
Of course you can synchronize the speed of the Wah to your host’s
tempo. Select a note resolution from the Speed/Sync drop down menu
next to the speed knob. T stands for triplets, * for dotted.
Envelope
When you set the Speed knob to maximum, the Wah Pedal will be
controlled by an envelope analysis method called “envelope follower”.
This means that the filter cutoff will be controlled by the input signal. In
this Auto Mode the Speed knob’s display reads “Env”.
Compressor
A compressor is a tool for controlling the dynamic range of an audio
signal. Technically speaking, it consists of an envelope detector con-
trolling a voltage controlled amplifier. Practically it limits volume peaks
and allows you to lift the volume of the quieter parts of the signal. Use
it to accentuate attacks or increase the sustain of your sound.
