Hey all,
I happened to be in the need of converting a few pieces of music written
using MuseScore and create Lilypond notation. That functionality seems
to have been originally been included with MuseScore but was removed
already some time ago.
As there was nothing that I could find that would do what I wanted (and
I probably also didn't look very hard), it seemed to be easier to simply
write one.
This converter doesn't attempt to be a full converter. There are too
many differences, and as the README already states MuseScore needs
trickery with articulations to get a bit more musical sound. It can at
least save you having to manually copy a lot of notes. I wrote it using
files saved by MuseScore version 4.4.3, so your milage with other
versions might vary.
