The <strong>en</strong>velope and LFO can be used to modulate the filter cutoff frequ<strong>en</strong>cy.<br />
AutoFilter Envelope Parameters<br />
The <strong>en</strong>velope is used to shape the filter cutoff over time. Wh<strong>en</strong> the input signal exceeds<br />
the set threshold level, the <strong>en</strong>velope is triggered.<br />
• Attack knob and field: Sets the attack time for the <strong>en</strong>velope.<br />
• Decay knob and field: Sets the decay time for the <strong>en</strong>velope.<br />
• Sustain knob and field: Sets the sustain time for the <strong>en</strong>velope. If the input signal falls<br />
below the threshold level before the <strong>en</strong>velope sustain phase, the release phase is<br />
triggered.<br />
• Release knob and field: Sets the release time for the <strong>en</strong>velope (this is triggered as soon<br />
as the input signal falls below the threshold).<br />
• Dynamic knob and field: Determines the input signal modulation amount. You can<br />
modulate the peak value of the <strong>en</strong>velope section by varying this control.<br />
• Cutoff Mod. slider and field: Determines the impact of the <strong>en</strong>velope on the cutoff<br />
frequ<strong>en</strong>cy.<br />
AutoFilter LFO Parameters<br />
The LFO is used as a modulation source for filter cutoff.<br />
• Coarse Rate knob, Fine Rate slider and field: Used to set the speed of LFO modulation.<br />
Drag the Coarse slider to set the LFO frequ<strong>en</strong>cy in Hertz. Drag the Fine slider (the<br />
semicircular slider above the Rate knob) to fine-tune the frequ<strong>en</strong>cy.<br />
Note: The labels shown for the Rate knob, slider, and field change wh<strong>en</strong> you activate<br />
Beat Sync.<br />
