You are aware that you can _quote_ the transposed/transposing clarinet
parts in score context and that the quote will appear in concert pitch,
namely taking the setting of \transposition into account and reversing
its effect on the notation?

It's conceivable to create two music functions masterToScore and
masterToPart where the first music function, when applied to a part like
\clarinet above (just writing \transposition instead of \transposing)
will _remove_ all \transposition statements in order not to mess up the
score Midi, and the second one will instead _heed_ all \transposition
statements and apply their _inverse_ to all following music in order to
make a difference for the _printed_ music in the part.

The disadvantage obviously being that \clarinet itself in "master input"
will not be suitable for either score or part without filtering it
further.
