The Rate control changes the frequency of the modulating LFO (0.01–10.0 Hz).The Depth control lets you adjust the amount of modulation applied to the Delay time.The Modulation controls let you adjust and/or randomize the delay time.The Shimmer control lets you randomize the Delay time, adding texture to the effect.The Stereo Width control lets you widen or narrow the effect’s stereo field.The Mix control lets you balance the amount of dry signal with the amount of wet signal. At 50%, there are equal amounts of dry and wet signal. At 0%, the output is all dry and at 100% it is all wet.
