Double générateur d'enveloppe de déclin CV analogique au format Eurorack, en kit DIY et en open source
2 independent voltage controlled decay EGs. The envelopes can be switched between triggered or gated (sustain) mode. The first trigger input is normalized to the second one and each channel provides a LED to visualize the envelope signal. The shape of the envelope can be adjusted between lin/exp 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. That includes a multi colour aluminum frontpanel, high quality jacks and smooth 9mm metal pots.
The project is open source, so the schematic is available, too.
