File Type 2Capella CapXML File
.CAPX File Association 2
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.
