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

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.

For in-depth information on the module take a look to our user Manual and Demo Video.

Listen to the above review!!!Review by Izmond
This module is awesome. The build is very easy and well laid out. But, the instructions mention putting the control board IC on at a time when you are still working on the main board. I thought, "I'll just put that on when I get to the control board", I did not remember, and I was even thinking about the review that warned me about this issue. I had a bad time. I was able to solder the ic bracket on from the top, but I was kicking myself (along with everything else in the basement) so hard. Great EG, my Befaco BF-22 never sounded better than when using the vc adsr. Highly recommended, but PAY ATTENTION. (Posted on 6/2/2017)
Pretty Straightforward missing one piece of info thoughReview by Ccorp
i think this module comes with 5 or 6 IC's in the instruction manual from Befaco it leaves out the IC on the control board, so be sure to put that on before the faders on the other side of the control board otherwise you are going to have a bad time. (Posted on 2/27/2017)
