I promised someone on this list I would scan a really old article from
Keyboard magazine by Bob Moog about String Tone Simulation. I figured others
might want to read it too. It describes the tonal characteristics of a real
violin, mentions a 36 band resonant filter that was once built to simulate a
violin body, and talks about possible ways to fake violin tones using effects
devices. I haven't read it in a long time, but seem to remember Moog saying
that really short delays creating a comb filter effect DO NOT work well
because of how the peaks and notches line up, they cause a metalic tube type
effect. I however DO use them. My theory was that if I used several of them
tuned differently and mixed them together, it would randomize those peaks and
notches and get rid of the metalic quality. It seems to work for me.
Remember also that Moog used to make a "String Filter". I believe MoogCE can
still make them.
If you want to read it, get it now. I may be dropping my AOL account by the
end of the month and it will be gone. The link is:

quality violins I found on the web. Link is:
