66 Chapter 6 Filter
AutoFilter
The AutoFilter is a versatile filter effect with several unique features. You can use it to
create classic, analog-style synthesizer effects, or as a tool for creative sound design.
The filter cutoff can be dynamically modulated using both a synthesizer-style ADSR
envelope and an LFO (low frequency oscillator). In addition, you can choose between
different filters types and slopes, control the amount of resonance, add distortion for
more aggressive sounds, and mix the original, dry signal with the processed signal.
AutoFilter Parameters
The main areas of the AutoFilter window include the Envelope, LFO, Filter, and
Distortion sections. The overall Threshold control is in the upper-left corner, and the
Output controls are on the right side of the window.
Threshold Slider
The Threshold slider sets the cutoff frequency—which applies to both the envelope
and LFO. When the input signal level exceeds the Threshold level, the envelope and
LFO are retriggered. The Threshold parameter always applies to the envelope. It only
applies to the LFO if the Retrigger button is selected.
Envelope Section
 Attack knob and field: Sets the attack time for the envelope.
 Decay knob and field: Sets the decay time for the envelope.
 Sustain knob and field: Sets the sustain time for the envelope.
 Release knob and field: Sets the release time for the envelope.
 Dynamic knob and field: Sets the amount by which the input signal modulates the
peak value of the envelope.
 Cutoff Mod. slider and field: Sets the intensity of the control signal’s effect on the
cutoff frequency.
