Bill 10Sep12: My understanding is that some (many?) chorus effect also apply a tiny pitch shift to the delayed/modulated signal as well.
A chorus is a Delay for which the delay time is modulated by a Low Frequency Oscillator (LFO). The most used LFO waveforms are sine and triangle.
Most modern chorus effect unit, be they plug-ins or hardware based, also spread the effect signal across the stereo field. Sometimes a parameter to control the depth and other behaviors may be encountered.
Some chorus effect also apply a tiny pitch shift to the delayed/modulated signal as well.
The effect can produce interesting sounds, one of which is to produce the illusion of more than one instance of the instrument/vocalist being present. What you get out of this effect, largely depends on your desire to experiment.
Play with the parameters one at a time and experiment.
Common parameters of a Chorus
| Delay Time |
Parameter Range : 0.0 to xxx.xx milliseconds This is your normal delay parameter. |
| Modulation Range |
Parameter Range : 0-100% or sometimes in milliseconds This determines the maximum amount of modulation applied to the delay time. |
| Modulation Rate |
Parameter Range : 0 - 20 Hz (frequency) Also sometimes referred to as the LFO frequency. Higher frequencies produce extreme effects. |
