Hey, Kim,
  I liked your patch, it has some very nice sound to it, and I like
being able to pan through the pluck/transducer location to hear all
the harmonics.  That's really cool.
  Now the way I see it, you could implement this as a sort of
ping-pong delay with the separate damping filters and *build-in* pd's
own 64-sample block delay time into the delay lines (subtract off the
approx ~1.5 ms for 64-samples).  This would mean that you have a
minimum delay time of ~1.5 ms for the forward and backwards travelling
waves (and consequently limits your fundamental freq--so, if you need
higher frequencies, that's when you would need to reduce the
blocksize).  Then, you just have to include a couple of taps on each
delay line to take the results and sum them together.
  I'll have another look at it later, and see if I can modify it.
