• Stereo Mode pop-up menu: Sets the input/output mode of the EVOC 20 Filterbank. The
choices are m/s (mono input to stereo output), and s/s (stereo input to stereo output).
Note: Set Stereo Mode to m/s if the input signal is mono, and to s/s if the input signal
is stereo. In s/s mode, the left and right stereo channels are processed by separate filter
banks. When you use m/s mode on a stereo input signal, the signal is first summed to
mono before it is passed to the filter banks.
• Stereo Width knob: Distributes the output signals of the Synthesis section’s filter bands
in the stereo field.
• At the left position, the outputs of all bands are centered.
• At the centered position, the outputs of all bands ascend from left to right.
• At the right position, the bands are output—alternately—to the left and right
channels.
Fuzz-Wah
The Fuzz-Wah plug-in emulates classic wah wah effects often used with a clavinet, and
it adds compression and fuzz distortion effects as well. The name wah wah comes from
the sound it produces. It has been a popular effect—usually a pedal effect—with electric
guitarists since the days of Jimi Hendrix. The pedal controls the cutoff frequency of a
bandpass, lowpass, or—less commonly—highpass filter.
Getting to Know the Fuzz-Wah Interface
The Fuzz-Wah interface is broken down into the following sections.
Effect Order buttons
Fuzz parameters
Auto Wah parameters
Wah parameters
• Effect Order buttons: Select whether the wah wah effect precedes the fuzz effect in the
signal chain—Wah-Fuzz—or vice versa—Fuzz-Wah. See Effect Order Buttons.
