LFO 1/2 Rate knobs and fields: Set the modulation rate for the left and right stereo
channels. In surround instances, the center channel is assigned the middle value of
the left and right LFO Rate knobs. The other channels are assigned values between
the left and right LFO rates.
Note: The right LFO Rate knob is available only in stereo and surround instances, and it
can be set separately only if the Link L & R button is not enabled.
Link L & R button: Link the modulation rates of the left and right stereo channels.
Adjustment of either Rate knob affects the other channel in stereo instances, or
other channels in surround instances.
Mix slider and fields: Determine the balance between the two LFOs.
Phase knob and field: Control the phase relationship between individual channel
modulations. Available only in stereo and surround instances.
At 0°, the extreme values of the modulation are achieved simultaneously for
all channels.
At 180° or −180°, you achieve the greatest possible distance between the modulation
phases of the channels.
Note: The Phase parameter is available for use only if the Link L & R button is active.
Distribution pop-up menu: Choose how phase offsets between individual channels are
distributed in the surround field. Choose from: circular, left↔right, front↔rear, random,
or new random. Available only in surround instances.
Note: When you load a setting that uses the random option, the saved phase offset
value is recalled. If you want to randomize the phase setting again, choose new random
from the Distribution pop-up menu.
Filter button: Turn on to introduce an additional allpass filter into the signal path.
This filter shifts the phase angle of a signal, influencing its stereo image.
Low/High Cut sliders and fields: Set the frequency at which the phase shift crosses
90°—the halfway point of the total 180°—for each of the stereo channels. In surround
instances, the other channels are automatically assigned values that fall between the
two settings.
Volume Mod slider and field: Determine the impact of LFO modulation on the amplitude
of the effect signal.
Output Mix slider and field: Set the balance between dry and wet signals.
