I think the trick is to use the property PianoStaff.instrument. See my template:
staffPiano = { \new PianoStaff { \property PianoStaff.midiInstrument = #"acoustic grand" \property PianoStaff.instrument = #"Piano" << \new Staff { \clef treble \notes { c } } \new Staff { \clef bass \notes { c } } >> } } \score { \staffPiano } _______________________________________________ Lilypond-user mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-user
