Trying out a new circuit I got from one of the modular group members. I SMD-ized this one so I could squeeze in 4 of the same circuit. Each stage uses 5 transistors...so that is a A LOT of little tiny components. Functionality is nice. Now I just need to balance this out with making an ADSR and I'll have all the envelopes I'll ever need hehe.
This circuit will also be used for a workshop in teaching others how to go from schematic to module. Should be fun.

More stuff to come.
