Grating online accordion sound?
Impressively, the site's Sheet Music collection seems to have more scores for accordion than for any other instrument. I've pointed many accordionist friends to it.
Unfortunately, the accordion samples the online player uses are TERRIBLE. They sound more like an out-of-tune bagpipe, or perhaps a car that won't start. (Some people wouldn't be able to draw much of a distinction between the two, but that's another topic.)
Any chance you could fix that? If you're using a soundfont, there are many free and far more musical accordion soundfonts out there.
Of course if the instrument sounds aren't coming from your end, but are instead cheesy MIDI sounds on my computer, you can safely ignore this.
