another module for my modular synth, the Behringer Chaos a clone of Mutable Instruments Marbles, adding envelope magic to my rack

Ulli, you finally got me, and I started into the world of modular synths.
After building some modules myself from plans of Hagiwo, I gave up
saving money and bought some cheap Behringer modules “Brains” and “Four Play” together with a power supply, and glued together my first self made rack from some old cabinet cardboard panels.
