For @Gelatian only. Click See Inside, export the sounds and then import them. There are a few designs in here, too. For the designs, remove the hidden text. The sounds titled 2 are the second loop of the sounds titled 1. And the first sound should replace Melody 1's sound and should have a second loop in the Subzero demo so it sounds better.
I turned off commenting so nobody can ask how I got the sounds inside in the comments section. @EricEpicGamer445 for the origin of the stuff hidden in here.
