Top half is a DUSG style function generator. Additions include an output SHAPE control, and voltage controlled gate DURATION via switch, knob, and cv input.

—

Bottom half is a vc decay envelope synchronized to the function generator via shared trigger and gate inputs. VC trigger delay allows the synchronization to be broken, and the TIME CV is sent to an internal S&H in order to stabilize the modulation throughout the duration of the envelope. This S&H voltage has its own output.
