   I've been thinking about this problem also, but along somewhat different
   lines. To me, Karplus-Strong and the Stanford delay-line implementation
   of PM are convenient but rather unphysical representations of the real
   world.  So I hope to avoid: a crude analog implementation of ... a crude
   digital implementation ... of an analog (physical) model. I'd rather try
   to make a direct, if crude, analog implementation of the physics without
   the delay-line approach. In other words, an analog computer for the
   one-dimensional nonlinear differential equation. So far I haven't made
   much progress. 

Um, the LC transmission line circuit (like on the Hammond organ) is
exactly a one dimensional differential equation.  Transmission line,
sound waves in a tube, wave on a string, it's all the same equations.
