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 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.
• 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.
