That looks great Lugia. I'll definitely be buying those Buchla clones, they look awesome.

I have the Behringer filters from Roland in my main rack which are awesome and the dual ADSR is great too with the inverted envelope, which comes in very handy for side chain. Just a note on the adsr's though, the travel on each slider is a bit strange in that if you want to make a pluck you have to set them really low. I'm not sure if the original Roland ones had the same behaviour.
