QUARTET CHORUS ENSEMBLE1095
Dry/Wet
This controls the mix of the dry and processed signals.
! Note that the Dry/Wet parameter can be set individually for each of the four chorus algorithms.
! Note that all chorus/ensemble effects require some amount of dry signal to produce the desired effect. There-
fore, 100% Wet also includes a certain amount of dry signal.
q If you are using Quartet as a send effect you would probably want to have the Dry/Wet knob set to 100%.
Chorus
The Chorus effect algorithm simulates multiple detuned “copies” of the input signal. The Chorus is basically a delay
line with adjustable feedback. The principle is to split the input signal in two, run one signal dry and the other through
the delay line, and then sum the two signals.
The picture below shows the basic principle of the chorus:
