Suggection about MusicXML

[foo123]

Hi, i am interested in building an interactive music editor (like MuseScore) entirely in javascript HTML5, using (parts of) Vexflow,

You can check the vexflow google group about this also.
The editor should be able to import/export to both MIDI and MusicXML, so i can extend the MusicXML parser you have started.

The project will be hosted possibly on GitHub
