Chorus effect

Updated November 10, 2013

Much like flanging, chorus mixes delayed copies of the signal back into itself while varying the delay time; the minimum delay is longer, however, so less-extreme comb filtering is produced. The result is a glossy, shimmering sound that is often applied to guitars. Chorus is usually described as an attempt to make one instrument sound like several playing in unison. In practice, that effect is rarely achieved, but chorus can add color to leads or thicken pads.

After setting the effect type to Chorus, you will see the following controls:

RATE In each channel, the delay time is modulated by two LFOs. The RATE knob sets the frequency of the first LFO, in Hertz. The rate of the second is a fixed fraction of that of the first.
BASE Sets the base delay length, in milliseconds, which is the length when both LFOs are at their zero positions.
DEPTH Sets the amount by which each LFO varies the delay length, as a percentage of BASE. At high values, the vibrato produced by the delay variation becomes perceptible.
OFFSET Sets the amount, in percent, by which the phase of the right channel LFOs are advanced relative to the left. Non-zero values produce dramatic stereo effects.
MIX Sets the effect mix, in percent. At 100, the output contains only the delayed signals; at zero, it contains only the unprocessed source signal.
