ADSR

Simple Envelope

A simple design offers snappy attack times, and wide decay/release times. Two outputs of the envelope signal and two inverted outputs allow it to be patched to several modules without the use of a multiple.
The envelope generator is triggered by a 0 to 5 V rising edge.
Circuit activity is indicated by a white LED.
All I/O signals are available internally via a pinheader on the PCB for prepatching the module inside the case.

Tunable parameters:
ATTACK (0.5ms – 3s)
DECAY (7ms – 16s)
SUSTAIN (0V – 6V)
RELEASE (7ms – 16s)

Inputs:
GATE IN

Outputs:
OUT 1
OUT2
INV OUT1
INV OUT2
