[L2Ork-dev] Bug with high pass and band pass filters

Hi Ico,

I just compiled pd vanilla 0.45.4 and I can confirm the bug is also 
present there. I contacted the user who reported it to be an extended 
only bug to know if he is sure about that and I also asked him to test 
my patch in his computer. If it turns out he was wrong about vanilla's 
filters being bug free (which is the very likely scenario), I will 
contact Miller about it and also report the bug at sourceforge. I will 
let you know about it as well.

Take care,
