This is an introduction and overview of the SE1 Shaped VC Envelope by Weston Precision Audio, available at Takazudo Modular.
The SE1 is an analog ADSR envelope generator module for Eurorack. It generates standard Attack/Decay/Sustain/Release type envelopes from a simple gate signal. Unlike many ADSR modules, the SE1 allows independent selection of the time/voltage characteristic for each stage (A/D/R) from log, linear, or exponential, enabling unique envelope shapes.
The detailed product description is currently being written and will be updated upon completion.

About Weston Precision Audio
Weston Precision Audio is a modular synthesizer maker based in North Carolina, USA.
We started carrying Weston Precision Audio after the founder, Devin, reached out to us by email about distribution. When the modules actually arrived, we still remember being struck by how beautifully made every single one was.
His modules show a real commitment to keeping that hands-on analog feel intact, and once you pick one up, the care he puts into materials and components becomes obvious — that is something we can promise.
Bonus: Modular Accessory Set by 電氣美術研究會 (Denki Bijutsu Kenkyukai) Included

In the hope that more people will get hands-on with modular synths, we have teamed up with 電氣美術研究會 to bundle a modular accessory set with this product.
The contents vary by season — patch cables, power cables, a dress-nut sample set, a mono splitter, and more. The set is included with the product, so please give it a try!
That concludes our introduction of the SE1 Shaped VC Envelope.
