I figured out how to create a full quad emulation with a nice UI using only one Envelope Factory per envelope generator. This is by far my favorite version. The only shortcoming I see is that changing the sustain state will instantly terminate any active envelope, which will also terminate looping if you have patched EOC to the gate input. But this seems like a fairly minor issue.
Version 3 should be my last quad emulation version.
