Regarding Score Downloads as a Pro Feature
I received an email today (and you probably did too) from MuseScore, saying how score downloads are moving to Pro, as detailed here: https://musescore.com/download-terms
I personally make, play, and arrange music for fun. I uploaded my scores to MuseScore because of the free score sharing. Clearly, if MuseScore wishes to make downloading scores a paid feature, I'll just have to host my scores somewhere else. I will still use MuseScore, and upload them to here, but I will include an alternate method for people to download my scores.
I urge others to do the same. I use MuseScore as a reference for, and as a central place to share my music. It has been, and should always be, free and open.
