Re: [xl7] PX-7 Filter Glitch/Bug?

2004-03-17 by Aaron Eppolito

Some of the E-mu 12th order filters are *really* hot and peaky.  With
certain sounds, those peaks can generate pops (basically, you're
peaking just the right frequency in the source material).  I do agree
that the factory sounds and especially the patterns shouldn't have Q up
so high on those presets.  Turn down Q a few notches and all will be
fine.

PS. there was a thread on this exact filter not too long ago which came
to the same conclusion you did (though not quite as fast as you did!)
