Emu XL-7 & MP-7 User's Group

Congratulations, you found the culprit of the problem (i.e the filter)
much quicker than people have in the past.  We had a relatively long
discussion on preset pops that took quite a while to track down in the
past.

An alternate solution (which may or may not change the sound less) is
to turn down Q ever so slightly.  Same deal.  The filter has a lot of
resonance that when combined with certain sounds, clips the filter.  As
a side note, you'll notice that most filters have their max Q set at 80
instead of 100.  At your own risk, you can turn them up... =)
