The Effects Chain Editor
Effects Parameters
Retrigger determines whether the gate timer will reset itself each time the sidechain signal
goes above the threshold. If it is "On", the timer resets itself, and therefore the gate stays
open as long as the signal is above the threshold, or keeps going above the threshold, within
the interval specified by Gate Time. If it is "Off", the gate closes down after Env Time
has elapsed, regardless off the sidechain level, and the sidechain level must fall below the
threshold and come back up again before the gate will open again.
Chorus
Chorus is an effect which gives the illusion of multiple voices playing in unison. The effect
is achieved by detuning copies of the original signal and summing the detuned copies back
with the original. Low frequency oscillators (LFOs) are used to modulate the positions of
output taps from a delay line. The movement of the taps causes the pitch of the signal to shift
up and down, producing the required detuning.
The choruses are available as stereo or dual mono. The stereo choruses have the parameters
for the left and right channels ganged, while the dual mono choruses have separate left and
right controls.
Fdbk Level is the level of the feedback signal from the LFO1 delay tap into the delay line.
Negative values polarity-invert the feedback signal.
Tap Lvl sets the levels of the LFO-modulated delay taps. Negative values polarity-invert the
signal. Setting any tap level to 0% turns it off.
Tap Pan sets the stereo position for a given tap's output. The range is -100% for fully left, to
100% for fully right.
Atk Time (attack time) is the time for the gate to ramp from closed to open (reverse if
Ducking is on) after the signal rises above threshold, adjustable from 0.0 to 228.0 ms.
Rel Time (release time) is the time for the gate to ramp from open to closed (reverse if
Ducking is on) after the gate timer has elapsed, adjustable from 0 to 3000 ms.
LFO Rate sets the speed of modulation of the delay lines with a range of 0.01 to 10 Hz.
LFO Dpth sets the maximum detuning depth of the LFO-modulated delay lines, with a
range from 0 to 50 cents (= 1/2 semitone).
Tap Dly adds extra delay in front of the LFO modulated delay taps from 0 to 230 ms.
L/R Phase or LFOn LRPhs adjusts the relative phases of the LFOs for the left and right
channels in the stereo Choruses.
