ADSR Envelope Generator
This Eurorack-format ADSR envelope generator includes a re-trigger input for multiple triggers -- while the gate input is high. If you don't have a keyboard or MIDI-CV with a trigger output, you can use the ADSR TRIG input for synchronous attacks and modulation effects, triggered by a master clock signal. Envelope generators with trigger inputs, were typical in some older analog synthesizers, such as ARP and EMU.
