Weston Precision Audio SE1

Offering a flexible spin on the most ubiquitous flavor of envelope generator, the Weston Precision Audio SE1 is a voltage-controllable ADSR envelope for Eurorack modular synthesizers. Each stage of the envelope offers voltage-control inputs, while the Attack, Decay, and Release shapes may be individually set to Linear, Exponential, or Logarithmic curves. Additionally, the unique Sustain CV input allows you to modulate the Sustain level with a secondary signal. State outputs allow you to trigger other envelopes depending on where the SE1's envelope is in its cycle, and Loop mode allows you to create custom LFO shapes—gate inputs will fire off the envelope, which will cycle its Attack and Decay stages above the set Sustain level, and will then Release naturally when the gate is removed. Make your modulations more interesting with the SE1 from Weston Precision Audio.
