Befaco VC ADSR

Befaco VC ADSR


befaco vc adsr

The VC ADSR is our take on the classic ADSR: now smaller, more powerful and user friendly.

The circuit is based in a dual transistor “Current Mirror” (a voltage controlled integrator) and switching logic

This compact unit features voltage control for each stage with manual faders to improve usability, feel and aesthetics.


A unique feature of the VC ADSR is the gate outputs for each stage of the envelope offering an extra level of control over your patch!


Envelope generation can be triggered and controlled with the use of the panel mounted push button or with the trigger/gate input.

Control of the response curve between each stage of the envelope (from linear to logarithmic/exponential) is provided by a potentiometer.


Phase Time Limits:

Attack:  Min 3.0ms (down to 200µS with negative CV) // Max 10s

Decay:  Min 2.8ms (down to 400µS with negative CV) // Max 10s

Release:  Min 2.8ms (with Sustain at maximum) // Max 10s
