and eventually we got some minimal documentation (after signing an NDA a mile thick) and worked the rest out ourselves (or rather, John did)!

Are they crazy? It sounds as if manufacturer of a new computer language compiler would only let you know how to write 'Hello, world!' program and checkbook balancer, but refused to reveal the language's actual syntax!

BTW, what do we know about those parameters? Do we enter frequency in Hz (or octaves or something) and gain in dB, or are those units more or less arbitrary? What about Q - I suppose it should be related to sigma of the Gaussian. Are the curves Gaussians at all?
