Hello,
First, excuse my poor english, but I've found a little bug in
the "\transposition" command (for MIDI output).
For ascendent transposition (trupet e.g.), " \transposition d' " works
correctly.
Also for descendant transposition (horn e.g.) " \transposition d " works also.
But for octave transposition (Contrabass e.g.), it doesn't works.
" \transposition c' " let the score inchanged, and " \transposition c "
(without ' or ,) descend the score for two octaves.
As far as I can see, this is exactly what you should expect if you read
the documentation.
In
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Displaying-pitches#Instrument-transpositions
you see that the argument to the \transposition command is the pitch you
want to hear when a c' is played, which obviously means that
\transposition c'
doesn't change anything, whereas
\transposition c
should provide a MIDI output that sounds one (not two) octave down
compared to the notation, which it also does as far as I can see (and
hear).

My version is "2.11.63"
Best regards, and congratulation for your big work.
