Buchla & Tiptop audio - 230t Triple Envelope Follower
Triple Envelope Follower Model 230t
Here’s another wonderful vintage design: three AC amplitude followers with excellent sensitivity and highly accurate CV reproduction of the incoming signal. Both sensitivity and decay time are adjustable across a wide range. The circuit is so sensitive, it can even produce output from the noise generated by rotating the sensitivity knob—pretty cool.
The pulse output can generate either a transient (trigger) or a sustained gate signal, depending on the switch setting. We’ve been using it extensively in our systems and discovering tons of creative patch ideas.
16HP
Sustained position creates a Gate at the Pulse output
Transient position creates a pulse / trigger at the Pulse output
Decay time controls both the decay of the CV output and for pulses, either increases the pulse length (sustained mode) or prevents re-triggering (transientmode). Time from 1 ms to 5 sec.
Sensitivity attenuates the incoming audio signal from Zero to Maximum
