> I'm not top posting. Summary ------- When \set Staff.midiInstrument comes before \transposition in music that is fed into \partcombine, the top staff of the score has that transposition applied to it in the MIDI output only. PDF output is as expected.
Demo ---- \version "2.10.33" \paper{ ragged-right=##t } untransposed = \relative c'' { \key c \major \set Staff.midiInstrument = "flute" R1 c4 c d d } transposed = \relative c'' { % Putting this midiInstrument command BEFORE the \transposition % causes the flute part above to be transposed % in the MIDI output (but not in the PDF output) \set Staff.midiInstrument = "trumpet" \transposition bes \key d \major R1*2 } \score { << \new Staff \untransposed \new Staff \partcombine \transposed \transposed >> \layout{ } \midi{ } } _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org http://lists.gnu.org/mailman/listinfo/bug-lilypond
