• Resonance knob: Boosts or cuts the signals in the frequ<strong>en</strong>cy band that surrounds the<br />
cutoff frequ<strong>en</strong>cy. Use of very high Resonance values causes the filter to begin oscillating<br />
at the cutoff frequ<strong>en</strong>cy. This self-oscillation occurs before you reach the maximum<br />
Resonance value.<br />
• Fatness slider and field: Boosts the level of low frequ<strong>en</strong>cy cont<strong>en</strong>t. Wh<strong>en</strong> you set Fatness<br />
to its maximum value, adjusting Resonance has no effect on frequ<strong>en</strong>cies below the<br />
cutoff frequ<strong>en</strong>cy. This parameter is used to comp<strong>en</strong>sate for a weak or “brittle” sound<br />
caused by high resonance values, wh<strong>en</strong> in the lowpass filter mode.<br />
• State Variable Filter buttons: Switch the filter betwe<strong>en</strong> highpass (HP), bandpass (BP), or<br />
lowpass (LP) modes.<br />
• 4-Pole Lowpass Filter buttons: Set the slope of the filter to 6, 12, 18, or 24 dB per<br />
octave—wh<strong>en</strong> the lowpass (LP) filter is chos<strong>en</strong> as the State Variable Filter.<br />
AutoFilter Distortion Parameters<br />
The Distortion parameters can be used to overdrive the filter input or filter output. The<br />
distortion input and output modules are id<strong>en</strong>tical, but their respective positions in the<br />
signal chain—before and after the filter, respectively—result in remarkably differ<strong>en</strong>t<br />
sounds.<br />
• Input knob: Sets the amount of distortion applied before the filter section.<br />
• Output knob: Sets the amount of distortion applied after the filter section.<br />
