Sly Grogan

SLY GROGAN is an envelope generator based on the design in Electronotes #86. It can produce a wide variety of different envelopes and bursts, perhaps most interesting is the ability to have the envelopes ringing after the attack stage. It also works well as a voltage controlled LFO, tho the module is neither a LFO nor a regular ADSR.
