Triple Envelope Follower Model 230t

Three envelope followers after the Buchla 230. Each turns the level of an audio input into a control voltage, offered on two outputs, and fires a pulse output: a gate while the signal lasts in the sustained position, a trigger in the transient position. Sensitivity sets the input level and decay time, from 1 ms to 5 s, shapes both the envelope's release and the pulse. Part of the Buchla & Tiptop Audio 200t series, made under licence from Buchla.
