Do not forget to unmute all instruments before you publish a new score
If you have some experience with creating or editing scores, the mixer is very helpful. Especially if you want to detect a note error, it is very good. But before you publish it here an musescore or you want to mail an audio file to someone, do not forget to unmute all instruments. Otherwise some instruments will be muted and you are astonished why this happened.
This happed to me yesterday with the variation set by Boismortier, an additional variation by me included. I posted it, but I realised that the cello was mute. So I had to update this and then everything went ok.
The mixer is a good debugger, if you have bugs in your score. 😀😀
