Thanks for the suggestion, David. Unfortunately, I can't seem to get
anywhere by redefining \@sa. Here's an example illustrating the difficulty:
it gives exactly the same result whether or not I redefine \@sa. (To ensure
it was using \sh etc., I had to redefine \bigsh etc because PMX uses the
latter.) That suggests to me that the TeX code for the example is never
using \@sa.

==============================
I've stared at the MusiXTeX coding for accidentals, but it'll be a very long
time before I can make any sense out of it at all, if ever.
The good news is that the transposition project demands lots of manual
intervention for other reasons (such as transposing the chord symbols), so
fixing the accidentals is no additional big deal.
