Chapter 9 Modulation 139
 LFO 1 and LFO 2 Rate knobs and fields: Use the left knob to set the modulation rate
for the left stereo channel, and the right knob to set the modulation rate of the right
stereo channel. The right LFO Rate knob is only available in stereo and surround
instances, and can only be set separately if the Left Right Link button is not enabled.
In Surround instances, the center channel is assigned the middle value of the LFO left
and LFO right Rate knobs. The other channels are assigned values between the left
and right LFO rates.
 LFO Left Right Link button (only available in stereo and surround instances): Switch on
to tie the modulation rates of the left and right stereo channels to each other.
 LFO Phase knob and field (only available in stereo and surround instances): Controls the
phase relationship between the 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. The LFO Phase parameter is only available, if the LFO Left Right Link button
is active.
 Distribution menu (only available in surround instances): Defines how the phase offsets
between the individual channels are distributed in the surround field. You can
choose from Circular, Random, Front <> Rear, and Left <> Right distribution. 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“ in
the Distribution menu.
 Vol.Mod. (Volume Modulation) slider and field: Use this to determine how much of an
impact the LFO modulation has on the amplitude of the effect signal.
 Output Mix slider and field: Determines the balance between dry and wet signals.
 True Analog menu (extended parameter): Use to introduce an additional all-pass filter
into the signal path. An all-pass filter shifts the phase angle of a signal, influencing its
stereo image.
 Analog Left and Analog Right sliders and fields (extended parameter): This controls 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
assigned values between the two settings.
