Four independent envelope generators with variable attack and decay times (range is .001 to 10 seconds) and a choice of sustained or transient operation. Input pulses initiate envelopes and optionally control duration time; output pulses, activated at end of decay, are particularly useful for advancing sequencers or looping to inputs to generate repetitive functions.
