[sdiy] Best way to test Morph Lag?

[appliancide]

Ok, this is a little embarrassing...

I wired the attack and decay pots backwards at first. When I fixed them, I got a bad solder joint that turned out to have about a 50k resistance. I fixed this and now the circuit now seems to be behaving correctly. 

It does seem to be influencing a single supply voltage buffer that I have on the same circuit board, but that is livable for now.
