*Making a chorus effect*
A chorus effect is obtained by taking a signal and mixing it with a slightly delayed copy of itself. This mix results in the audible phasing artifacts that are typical for a chorus effect. The delay is modulated by an LFO, adding variation to the phasing.

-> This example achieves stereo modulation by shifting the LFO's phase on one channel. 
-> Instead of a sine wave, the LFO uses a smoothed triangle wave. The smoothing is achieved with the slide~ object, for which the smoothing time needs to be specified in samples. The MsToSamps subpatch makes sure the samples matches Live's current sample rate.
-> You will notice that that the result is slightly attenuated especially for a low depth value, i.e. for a small maximum delay of the modulation. This compensates for the extra amplitude gained by adding an almost identical copy of the signal.
-> For a more sophisticated Chorus effect, more delayed copies of the signal could be added.

Adding a feedback loop in the delay line adds even more phasing artifacts. The $Link Flanger example <Set:../../Flanger/Flanger.als> demonstrates this.
