Build Status

The primary goal of this project is to provide a library to convert NWC scores to MusicXML. Then, Noteworthy users will be able to share their scores with others scorewriters, especially free ones such as MuseScore. For the time being, the library support only NWCtxt and you need a copy of NoteWhorthy composer to save a NWC file to NWCtxt.

The converter is also available online as a webservice on Google App Engine at https://nwc2musicxml.appspot.com/

If you find the software useful you can donate.
