In an effort to fix an issue on an old (prior to V.2.2) score I re-uploaded it several times. In that process the original sound was lost at musescore.com. It sounds fine locally using the Mellow Yamaha Grand with the MuseScore_General.sf3 soundfont which has been saved to the score. However, when the score is uploaded it has a very different sound when played back from musescore.com. What am I missing? Do I need to contact musescore.com about this issue?
