Advanced Chorus Parameters
DELAY TIME
– Adjusts the minimum delay time from 0.0–50.0 ms. Lower values create a more unified
sound while higher values go beyond double tracking towards “slap back.”
LOW CUT
– Adjusts the cutoff frequency of a high-pass filter at the output of the processed signal. This
control removes bass frequencies and can be useful to create chorus effects designed for bass guitar.
HIGH CUT
– Adjusts the cutoff frequency of a low-pass filter at the output of the processed signal.
Decreasing this value creates a darker chorus effect reminiscent of an age when typical effects were unable to
reproduce the full frequency spectrum. Lower this to achieve those sounds some might call “warm.”
LFO PHASE
– Adjusts the phase differential between left and right LFO waveforms, which creates a
noticeable effect on the stereo width of the chorus.
LFO TYPE
– Sets the “shape” of the modulation. Sine and Triangle are the most commonly used waveforms.
Note: Whenever the number of voices is set to more than two, the LFO type will be changed automatically to
“
SINE.
” If the number of voices is greater than two and the LFO type is changed to something other than
“SINE,” the number of voices will be reset to two.
for more information on LFO waveform shapes and phase.
AUTO DEPTH
– Scales
DEPTH
to create a consistent sound at any
RATE
. This control simplifies dialing in
“musical” results. For precise control or wild sounds, you may wish to turn it OFF.
PHASE REVERSE
– Allows Left, Right or both channels of the effect to be phase inverted.
DRIVE
– This control allows you to simulate the gentle distortion produced by overdriving an “analog bucket
brigade” delay chip of the type used in many vintage chorus effects. Set to zero for “pristine clean.”
WIDTH
– Widens the sound, creating a difference between left and right delay times by scaling the right time
downwards
from the value set (see
DELAY TIME
, above) toward
1 ms
as width goes from 0–100%.
LFO2 RATE
– Adjusts the rate of the secondary LFO. This LFO modulates the primary LFO and can be used to
create more interesting effects.
LFO2 DEPTH
–Adjusts the depth of the secondary LFO.
STEREO SPREAD
– Controls stereo width by setting the pan position of the two delays from hard-panned
(100%) to dead center (0%).
DIMENSION MODE
– Allows simulating the famous “Dimension” style rackmount and pedal chorus units:
Off: Dimension mode is not active.
Low: A neutral version of the Dimension with no tonal coloration.
Med: Classic Dimension processing buttons 1-3. Set
RATE
and
DEPTH
to taste.
High: Classic Dimension processing button 4. Set
RATE
and
DEPTH
to taste.
