Website instrument playback
Recently I downloaded a bunch of sound files because I wanted a different piano sound for some of my scores. Everything worked fine in MuseScore, I was able to get it to work in playback. But, after uploading a score to this website, I've found it still uses the default piano sound. I have no idea how to make the online player use one of the sounds I've downloaded, so I'm asking here.
The score in question, if it helps: https://musescore.com/crono23/universal-fox-trot
