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:

Also of possible interest are 3D frequency/time plots of good and poor 
quality violins I found on the web.  Link is:

This and many other articles from Keyboard are contained in a Hal Leonard 
book called "Synthesizer Technique". Lots of articles by Moog, Patrick 
Gleeson, Craig Anderton, Roger Powell, and others. All articles written 
between '78 and '86; plenty of info on analog techniques.
