Detailed Description

The GS reverb: a Schroeder/Dattorro tank transcribed from the engine.

Input conditioner, then four series allpass diffusers, then two parallel tanks each with a damping lowpass and two nested allpasses, then eight output taps. All eight GS types share this topology — Delay and PanDelay simply zero the diffusers and collapse to a single long tap.

The write cursor decrements, so every tap offset is added to it.
