Detailed Description

The GS chorus: a modulated delay line with two anti-phase taps.

A 24-bit signed sawtooth drives a triangle from its magnitude; the two taps read 180° apart, which is what makes the output stereo from a mono send. The engine has a companion right-hand stage, but it is gated off for every GS type, so the left stage alone is correct.
