That was not the point of the doepfer anunchment, Doepfer claims that the
filter is 6db instead of 12db, as far as i can see the original filter
design is 12 db. Take alook at the "emulated" filter responces they show
at their web page, so "smooooth" its quite relistic that they are simulated
not real! :-)

I was a pedalling a bit of irony ower Doepfers anounchment, they make
such a big fuzz ower something allready known to many as if it
was their invention wich is plain silly. Some times Dieter Dopfer
is just a plain copy machine! I dont condem him on copying, many does
but by making a copy to his own invention that i condem.

Otherwhise you said that 6db hp + 6db lp , that does not make a 12dbBP, 
each slope are still 6db so thats a 6db BP!
