I'm a member of a button accordion forum called melodeon.net. There's been discussion recently about converting ABC (which many members use) into normal scores ('tadpoles'), eg http://forum.melodeon.net/index.php/topic,4683.20.html. Many members use a free service on a site called The Montreal Tunebook session: http://music.gordfisch.net/oregans/miscellaneous/editor.php. This works really well, but I wanted to be able to edit the result using MuseScore 0.9.6.2, so as to be able to add chords, change the tune, etc, etc. I suggested this to the forum, and someone suggested using http://abc2xml.appspot.com/. So I did, but it doesn't seem to work as well as the Montreal site. I tried three examples of ABC notation, and one was pretty close, one presented the score very strangely, and the third only managed to convert the title and the time signature.
I can provide examples in pdf for comparison, if that would assist.
It would be superb if you could use MuseScore for this, because there are a lot of melodeon.net members who would immediately see the advantages, who already use the software in other ways.
I have XP home edition. Latest version of MuseScore 0.9.6.2 just recently downloaded.
