3310 Envelope Generator (EG)

3310 Envelope Generator (EG)

Featuring the AS3310 IC (based on the classic CEM3310 IC), the 3310 Envelope Generator (EG) offers a simple, but effective four-stage design; ideal for modulating VCAs, filters and other modules.



  • Controllable exponential attack, decay and release.
  • Controllable linear sustain (up to 10V).
  • Gate input has a dedicated comparator with an adjustable threshold (between 1V to 10V).
  • Gate through output, allowing for multiple EGs to be chained together.
  • Retrigger input for modulation sources such as LFOs etc.
  • Green LED indicator provides a visual representation of the output level.
  • Ergonomic design.
  • Hand-built and tested in the UK.
