[MusicXML] Voice 0 not imported

Type
Functional
Severity
S4 - Minor
Status

Project
MuseScore

Steps to reproduce bug
1. Open the attached file: tmpCM5s1G.xml

Expected behavior: MuseScore should display a G upstem and an E downstem (see expected.PNG attached)

Actual behavior: MuseScore displays an E downstem only (see actual.PNG attached)

Discussion: The line that causes problems for MuseScore is: <voice>0</voice> (MuseScore imports the file correctly if the voice numbers are greater than 0). But zero is valid MusicXML. It can be any unique string. See http://www.musicxml.com/UserManuals/MusicXML/Content/EL-MusicXML-voice…

The MusicXML file was created by the Music21 library. For the relevant discussion on this topic see the last few posts on the following thread: https://groups.google.com/forum/#!topic/music21list/XX2-VO-4oxA

MuseScore version: 1.3 and also nighltybuild of 2.0 ( c4e95c7 )

(Operating System: Windows 7)

MuseScores MusicXML importer indeed assumes voices to be identified by integers greater than zero. As the MusicXML specifications allows any string, this is obviously a bug.
