In a traditional ADSR envelope, there are separate controls for the Decay and Release time. However, most often I tend to set Decay and Release to roughly the same value. This gives the decay and release portion of the sound the same time constant, which often sounds natural. In this ASR envelope module, there is a single control (named Release) that sets the time constant of both the decay and release phases.

The simplified envelope allows for a compact (4 HP), completely through-hole design with a single PCB. In addition to the usual Gate input and envelope Out, there is a Loop switch which turns the ASR into a handy LFO with separate rise (Attack) and fall (Release) times.

The envelope has an 8Vp output range, and time constants ranging from a snappy 1.5 ms up to approximately 1s. The traditional logarithmic output curves are a good match with a linear VCA such as my Dual VCA module.
