• LFO Phase knob and field: Available only in stereo and surround instances, it controls
the phase relationship between individual channel modulations.
• At 0°, the extreme values of the modulation are achieved simultaneously for all
channels.
• 180° or −180° is equal to the greatest possible distance between the modulation
phases of the channels.
Note: The LFO Phase parameter is available only if the LFO Left Right Link button is
active.
• Distribution pop-up menu: Available only in surround instances, it defines how the phase
offsets between the individual channels are distributed in the surround field. You can
choose from “circular,” “left↔right,” “front↔rear,” “random,” and “new random”
distributions.
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.
• Volume Mod(ulation) slider and field: Determines the impact that LFO modulation has
on the amplitude of the effect signal.
• Output Mix slider and field: Determines the balance between dry and wet signals.
• All Pass button (Extended Parameters area): Introduces an additional allpass filter into
the signal path. An allpass filter shifts the phase angle of a signal, influencing its stereo
image.
• All Pass Left and All Pass Right sliders and fields (Extended Parameters area): Determines
the frequency at which the phase shift crosses 90° (the half-way 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.
