About MusicXML
Lessonator™ can load MusicXML files and associate them to a slide. The MusicXML file is converted to an internal file format that is optimized for Lessonator™.
MusicXML is an XML-based file format for representing Western musical notation. The format is proprietary, but fully and openly documented, and can be freely used under a Public License. As of 2013, MusicXML is supported to varying degrees by over 160 notation programs. These programs include: Most scorewriting programs, including Finale, Sibelius, capella, and MuseScore.
Most Music OCR programs, including SmartScore and PhotoScore.
Some music sequencer programs, including Cubase, SONAR, and Rosegarden.
Additionally, web support is possible through the use of the HTML5 canvas element and JavaScript resulting in the rendering of legible music within a web browser.
Note that no application supports MusicXML 100%, like no web site uses 100% of the features of HTML4. Each application is written differently and furthermore there are regional and domain-specific differences in music notation conventions.
