I post here the new debug version
My modifications haven’t changed but since I posted it, many improves have been made on Musescore 3, which makes this version way more stable
I also post some files which can be useful with my debug version (examples I made, empty sheets…)
(To run the program: win32install→bin→MuseScore.exe)
