Re: MIDI instrument for oboe d'amore

[Jacques Menu]

The pitch to use for \transposition should correspond to the real
sound heard when a c' written on the staff is played by the
transposing instrument. This pitch is entered in absolute mode, so an
instrument that produces a real sound which is one tone higher than
the printed music should use \transposition d'.  \transposition should
only be used if the pitches are not being entered in concert pitch.

After using \transpose, they are not in concert pitch.

BTW, it could be better named as something like

\transposingInstrument, it seems.

Why?

Would be more explicit: transposition can be understood as the act of
transposing,

"transposition" is not a verb.  And it describes the relation between
printed pitch and Midi pitch without necessarily referring to an
instrument.

That wasn’t clear to me from the doc.

       \context Voice = "Part_POne_Staff_One_Voice_One" <<
  \transposition a
         \transpose a c' % <<<<<<========= HERE
         \Part_POne_Staff_One_Voice_One

Thanks David, that solves my problem!
