AutoFilter LFO
The LFO is used as a modulation source for lter cuto.
LFO parameters
•
Coarse Rate slider and eld: Drag to set the speed of LFO modulation. Use to set the LFO
frequency in hertz.
Note: The labels shown for the Rate knob, slider, and eld change when you activate Beat
Sync. Only the Rate knob and eld are then available.
•
Fine Rate knob: Rotate to set the speed of LFO modulation. Use to ne-tune the LFO frequency.
•
Beat Sync button: Turn on to synchronize the LFO to the host application tempo. You can
choose from bar values, triplet values, and more by using the Rate knob and eld.
•
Phase knob and eld: Rotate to set the phase relationship between the LFO rate and the host
application tempo—when Beat Sync is active. This parameter is dimmed when Beat Sync
is disabled.
•
Decay/Delay knob and eld: Rotate to set the time it takes for the LFO to go from 0 to its
maximum value.
•
Rate Mod. knob and eld: Rotate to set the LFO frequency, independent of the input signal
level. Typically, when the input signal exceeds the threshold, the modulation width of the LFO
increases from 0 to the Rate Mod. value. This parameter allows you to override this behavior.
•
Stereo Phase knob and eld: Rotate to set the phase relationship of the LFO modulations
between the two channels (stereo only).
•
Cuto Mod. slider and eld: Drag to determine the impact of the LFO on the cuto frequency.
•
Retrigger button: Turn on to start the LFO waveform at 0 each time the threshold is exceeded.
•
Waveform buttons: Click to select the shape of the LFO waveform: descending sawtooth,
ascending sawtooth, triangle, pulse wave, or random.
•
Pulse Width slider and eld: Drag to alter the curve shape of the selected waveform.
