So I'm basically working on another device, called the Vocaloid Gun. It uses the same mechanics as my other project, "Guns". Only major difference is I will summon Fireballs (Maybe WitherSkulls. You decide since this is not yet complete :D) in place of items. Also, I would play a song in the process.
This is where the problem comes in. I don't know how to modify sounds and still failed even with step-by-step tutorial. I need your help to make the files to records. I will give you the files and make them into resource packs. I will give you credit for giving me immense help as this is my only dilemma in making the map. Thank you in advance :)

Edit: Now solved! See the map here :)
