Hello,
I'm new to this list. This topic immediately got my attention because of
some surprising statements related to music theory that were posed.

I don't understand what you mean with "theory-of-musical-harmony". Not
intended to repeat an earlier discussion on another list, but C and B# are
definitely not the same. They happen to represent the same frequency in
equal temperament but that's all. On keyboards with 12 fixed pitches per
octave (like a piano) they will also be represented by the same key,
whether tempered equal, according to Werckmeister's theories or else.
However theoretically they are different notes. That's one big part of the
problem piano tuners have to deal with. Very recently I published an
external for Pure Data (http://student-kmt.hku.nl/~funs/software.html) that
translates midi notes to frequency with a variable semitone and a settable
modulation (set of notes to be represented by the 12 keys). One of its
effects is that B# and C represent a different frequency unless a semitone
is exactly set to half a whole tone (like in equal temperament, equal
division in 12). I don't feel anything breaking in any case, or I might
have understood you wrong.
