Tremolo Effect
The Tremolo effect modulates the amplitude of the incoming 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.
Waveform display: Shows the resulting waveform.
Rate knob and field: Sets the frequency of the LFO.
Symmetry and Smoothing knobs and fields: Use these to alter the shape of the LFO
waveform.
If Symmetry is set to 50% and Smoothing to 0%, the LFO waveform has a rectangular
shape. This means that the timing of the highest and lowest volume signals is equal,
with the switch between both states occurring abruptly.
Phase knob and field: Available only in stereo and surround instances. Controls the
phase relationship between the individual channel modulations. At 0, modulation
values are reached simultaneously for all channels. Values of 180 or −180 indicate the
greatest possible distance between the modulation phases of the channels.
Distribution pop-up menu: Available only in surround instances. Defines how phase
offsets between individual channels are distributed in the surround field. You can
choose from “circular,” “leftright,” “frontrear,” “random,” and “new random”
distributions (to randomize the phase, choose “new random”).
Offset slider and field (Extended Parameters area): Sets the amount that the modulation
(cycle) is shifted to the left or right, resulting in subtle or significant tremolo variations.
