@ShortDescription
Numerically Controlled State Variable Filter

@Description
#name is a monophonic process block that simultaneously applies multiple filters
(high pass, low pass, band pass and notch) to the input signal. Each filter is available
on a different output of the process block. 

The filter parameters are driven by the 2 control inputs (Cutoff and Resonance) and are fully
interpolated, so you can modify them at audio rates without causing any glitches in the audio
being processed. 

The Cutoff input allows you to set the center/cutoff frequency of the various
filters. The Resonance input allows you to control the resonance at the cutoff 
frequency. The Resonance control signal is the inverse of the Q factor of the 
filter (1/Q).  Larger Q's will increase the peaking at the cutoff frequency.
