I am trying to create a musicXML file with 2 voices: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE score-partwise PUBLIC "-//Recordare//DTD MusicXML 4.0 Partwise//EN" "http://www.musicxml.org/dtds/partwise.dtd"> <score-partwise version="4.0"> <part-list> <score-part id="P1"> <part-name>Music</part-name> </score-part> </part-list> <part id="P1"> <measure number="1"> <attributes> <divisions>1</divisions> <key> <fifths>1</fifths> </key> <time> <beats>4</beats> <beat-type>4</beat-type> </time> <clef> <sign>G</sign> <line>2</line> </clef> </attributes> <note> <voice>1</voice> <pitch> <step>F</step> <alter>1</alter> <octave>4</octave> </pitch> <duration>2</duration> <type>half</type> </note> <note> <pitch> <step>G</step> <alter>0</alter> <octave>4</octave> </pitch> <voice>1</voice> <duration>2</duration> <type>half</type> </note> <note> <pitch> <step>C</step> <alter>0</alter> <octave>4</octave> </pitch> <voice>2</voice> <duration>2</duration> <type>half</type> </note> <note> <pitch> <step>A</step> <alter>0</alter> <octave>3</octave> </pitch> <voice>2</voice> <duration>2</duration> <type>half</type> </note> </measure> </part> </score-partwise>
It seems ok to me: the notes are in the same measure. But when I use musicxml2ly and then lilypond I get the second voice shifted to the next measurement. What is wrong?
