I forgot to mention that part. In that MP3 I'm running the motm through a 
something like a 32 or 36 stage phaseshifter in a Roland SE70 to generate a 
complex series of peaks and notches. Then I'm using some parametric EQ to 
tailor the sound, such as boosting the main body and air resonance frequencies. 
Then it goes through a resonant 32 band filter bank patch in a Nord Modular. 
That filter bank was set up to sort of mimic the Moog String filter. However, 
if used by itself, it doesn't really give much of a wood-like tone. The phaser 
and EQ are probably contributing more in the MP3. I was trying to get away from 
using a bunch of delay lines in parallel as I did in my Nord Mod strings from a 
few years ago. But it is becoming clear to me that using devices that create a 
lot of unknown notches or peaks in the audio spectrum doesn't quite give me the 
exact sound I want (although for my acoustic guitar simulations, they work 
great). Some notes sound OK, some sound ugly, I get hollow tones, or metalic 
tones. I'm now trying to get rid of the phaser and EQ altogether and use a 
really flexible parametric filter bank patch and then painstakingly set it up 
to give me the exact harmonic structure I want. But that requires looking at 
violin body plots and the harmonics of different notes and trying to come up 
with filter bank settings that can get me close to what I see.
