Chorus/Vibrato/Flanger

With this effect, the sound is delayed by a time value that varies up and down in a continuous movement. Because of the so-called Doppler effect, the pitch will also swing up and down. This is used for chorus and vibrato.

How does Chorus/Vibrato/Flanger work?
You may control how much the delay will vary up and down, as well as its speed. For vibrato, both of these values should be set quite high. For chorus, both of these values should be set low, which will diminish the vibrato effect and simulate two sound sources instead of one.

Values that may be set:
Frequency
controls the speed of the rising and falling delay time. If the frequency is set high, the variations in pitch will be fast.
Depth controls the maximum delay time. If the depth is set high, the variations in pitch will be great.
Feedback controls how much of the treated sound will be sent back through the effect box. Alot of feedback creates what is called a flanger effect.
Mix determines how much of the treated sound will be included in relation to the original.
