This reverb processor is an adaptation of the design discussed in [dat97a]. Tuned for a soft attack and smooth ambience, it consists of a network of twelve delay lines of varying length. At its heart, two of these are modulated very subtly, in a chorus-like fashion.

The bandwidth control reduces high-frequency content before it enters the ‘tank’, while damping controls how quickly the reverberating tail darkens.
