Program Documentation

To generate the program documentation with DoxyGen, type

cd build
make doxy

Browse the documentation with your favourite html browser at build/Doc/html/index.html


cd build.release/mscore

to start MuseScore. On first invocation a demofile is shown. You probably want to change that in the "Preferences" dialog.


A debug version can be built by doing make debug above, instead of make release.

To test the debug version, type

cd build.debug/mscore
