This script allows players to use programs like Aria Maestoa to automatically play the piano in game. I was just recently going to add it to my server until I realized that this version of the pianomidi doesn't exist anymore/I can't find it on the 1st or 2nd page of google.
Installation: Step 1: Unzip Step 2: Drag and drop into your addons folder Step 3: Restart your server
After the addon has been added to your addons folder it will let people use a midi player to play piano music!
