Hi there, now that someone gave me a Max license and I'm translating some patches to Pd, I guess I'm gonna start bugging you guys a lot asking for equivalent objects in Pd ;)

And here I ask about [filtercoeff~] and [filtergraph~]...

Based on filtergraph~, filtercoef~ calculates filter coefficient for the biquad~ object from frequency, amp & Q.

They seem to make it really easier and friendlier to use the [biquad~] object. Maybe this could be worked out as some abstraction, maybe someone already has. The math just blows me away and I have completely no idea whatsoever...

Cheers
