Actually I've just read a nice, not too mathematical explanation of
biquad-filters in Perry Cook's book "Real Sound Synthesis for
Interactive Applications" which I'm currently reading. It's a bit too
expensive to buy just for the biquad pages, but maybe you can find it
in a library.

Nice percussion patch btw. it's very similar to what Cook is
writing about in his book in the filter chapter.
