Description

Doepfer's voltage controlled decay: an envelope with a single time, its decay (as on the TB-303), and a gate of voltage controlled length drawn from it.

Key features

  • Trigger input; attack fixed at about 0.2 ms, decay from about 2 ms, set by hand and by a CV input with attenuator
  • Envelope output with its LED
  • Gate and inverse gate outputs taken from the envelope at an adjustable threshold, with a Gate LED
  • A voltage controlled gate length or trigger delay, for instance with the A-155 sequencer
  • Attack and shortest decay times can be changed by swapping a capacitor
