Musical score created by Capella, a composition program used for creating and editing musical scores; contains notation and other song data, such as text and graphics.

CAPX files are compressed .ZIP archives that contain an .XML file called score.xml. While CapXML is a proprietary format specific to Capella, the XML is similar to the standard MusicXML (.MXL) format. Therefore, it is possible for other music composition programs to parse the notation contained in a CAPX file.
