new here plus a question...

    You are going to have to forgive us.  We are music dudes.  The linear aspects of
circuits just don't interest us much.  As far as just modeling the circuit for the
sake of doing so, you should probably try to find a spice program.  If you want to
model the linear aspects of filters and amplifiers and stuff, that can be done with
some fairly simple arithmatic.  The one book I can think of that has some of this
stuff in it would be Musical Applications of Microprocessors by Hal Chamberlain (out
of print, moderately difficult to get).  I also have another book, but I don't
remember the name of it.  It is a reprint of some articles that were in some digital
audio journal of some sort.  It has all sorts of articles on modeling all kinds of
stuff that produce sound.
