Circuit can be found here; http://www.thatcorp.com/datashts/dn129.pdf

What are R11 and R12 doing? They're not mentioned in the design note so I assume it's obvious but I can't figure it out :D

The release time is slow, a number of seconds slow, and I can't see why. Removing C4 and C2 make no difference. Adding a low value drain resistor to U2D +IN helps in speeding it up but I'm not sure how it may negatively effect the circuit, if at all?

 
The resistor divider limits the max  voltage that can reach the VCA EC port to roughly +1/2V.  A higher DC voltage at that port might damage or at least  interfere with normal VCA operation.
