Sigh... please disregard this. It works fine. I just had the wrong
expectations. I assumed incorrectly that for purposes of relative
pitch calculation, the harmonics would be ignored, allowing you
to focus on the base string pitches.
It requires a bit more arithmetic this way, but it's logical enough.
Thanks for the patch -- you've fixed the biggest problem in my
150-page pile of arrangements!
