Chapter 8 Modulation 107
Tremolo
The Tremolo effect modulates the amplitude of a signal, resulting in periodic volume
changes. You’ll recognize this effect from vintage guitar combo amps (where it is
sometimes incorrectly referred to as vibrato). The graphic display shows all parameters,
except Rate.
 Depth slider and field: Determines the modulation amount.
 Rate knob and field: Defines the frequency, and therefore the speed, of the LFO.
 Symmetry and Smoothing knobs and fields: Use these to set the shape of the modulation.
 Phase knobs and fields (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.
 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.
Symmetry and Smoothing
If Symmetry is set to 50% and Smoothing to 0%, the modulation has a rectangular shape.
This means that the timing of the full volume signal is equal to that of the low volume
signal, and that switching between both states occurs abruptly. You can define the loud/
quiet time ratio with Symmetry and make it fade gently in or out with Smoothing.
