It probably wouldn't sound terribly great; the site doesn't make any attempt to make sure that the flipped version is in the same key as the original (and in fact that would be extremely difficult, if not impossible), so you'd get a rather dissonant-sounding MIDI. I was curious though, so I tried it out on the Für Elise example.
