The envelope is used to shape the filter cutoff over time. When the input signal exceeds the set threshold level, the envelope is triggered.
On/off switch: Turn the envelope section on or off.
Threshold knob and field: Set an input level that—if exceeded—triggers the envelope or LFO that dynamically modulates filter cutoff frequency. See AutoFilter LFO and AutoFilter filter.
Note: Retriggering of the envelope or LFO occurs only if the Retrigger button is active.
Dynamic knob and field: Determine the input signal modulation amount. You can modulate the peak value of the envelope section by varying this control.
Attack handle and field: Drag the handle horizontally (or field vertically) to set the envelope attack time.
Decay handle and field: Drag the handle horizontally (or field vertically) to set the envelope decay time.This handle sets both the decay time and sustain level.
Sustain handle and field: Drag the handle (or field) vertically to set the envelope sustain level. If the input signal falls below the threshold level before the envelope sustain phase, the release phase is triggered.
Release handle and field: Drag the handle horizontally (or field vertically) to set the envelope release time. This is triggered as soon as the input signal falls below the threshold.
