Hi Dieter.
Apologies, I did not see your previous detailed explanation.
Thank you very much for your reply and taking the time to test my query.
I never noticed this behavior when I first used the filter but -36dB is, for me, a usable level to deal with - I suspect that I may be patching things now a little differently, possibly with regards to VCA gain, which has made it noticeable than it did to begin with.
Either way, it is great sounding filter and so long as I know that this behavior is inherent in the design... it is something that I am prepared to live with.
Kind regards and best wishes
Tolly Hamilton
