Für Elise | Piano Contest

It would be fun to start an ongoing, informal piano competition. You can fork this ditty and write your loops, synths, and filters to play the Für Elise with the best-sounding piano sound possible.

I want to participate in this competition, but I need to learn more about sound synthesis. Therefore, it will be appreciated if you all share tips and links to resources about sound synthesis in the comments of this ditty so we can all learn from it.
