Chorus
The Chorus effect allows you to make your audio sound fuller. It can make a single instrument sound like there are actually several instruments being played. It adds some thickness to the sound, and can be described as 'lush' or 'rich'. Sound Set 1 is example of the chorus effect in action.
In the Properties Window you can change the effect properties. It's possible to select the necessary preset from the dropdown list or set custom values for Mix Depth, Feedback Gain, Delay Rate, etc.
