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