The Sonic Potions Descent is an analogue dual envelope generator. It provides 2 independent voltage controlled decay EGs. The envelopes can be switched between triggered or gated (sustain) mode. The first trigger input is normalised to the second one and each channel provides an LED to visualise the envelope signal. The shape of the envelope can be adjusted between linear and exponential with a trimmer on the back of the PCB. Decay times are adjustable between a few ms up to several seconds.
It comes as a complete kit with all needed parts to build it. This includes a multi colour aluminum frontpanel, high quality jacks and smooth 9mm metal pots.
This project is open source, so the schematic is available, too.
