Random Source Serge Extended ADSR

Random*Source brings Serge's classic Extended ADSR design to Eurorack format, providing a classic synthesizer envelope with an uncommon level of control. Adapted directly from the original Serge circuit, the Extended ADSR is a DADSR envelope rife with opportunity for CV modulation.

The Extended ADSR features dedicated controls for envelope Delay, Attack, Decay, Sustain, and Release—and additionally offers a dedicated CV input for each of these parameters, great for adding nuance to your patches' articulations. The module also includes a "VC All" input, which scales all envelope time stages proportionally so that you can maintain the same shape while scaling the envelope's overall duration. You can also switch your attack and release curves from exponential to linear, allowing this envelope to pair well with basically any modulation destination.

If you're looking for the general utility of a classic ADSR with the extensive control options that have made Serge so famous, look no further than Random*Source's Serge Extended ADSR.
