// description:
// First 30 seconds or so of the obligatory "stranger things" theme. I didn't make any serious attempt to perfectly clone the original sounds, but I feel like they live in a similar sonic universe. For my own convenience, this depends on the TheoryQuark from https://github.com/shimpe/theoryquark : just unpack it in the directory that opens when you open scide -> "file menu" -> "open user support directory" and then restart scide (or recompile the class library using the "language" -> "recompile class library" menu). It uses some instruments I made myself, as well as some I collected from sources which unfortunately I don't remember (probably sccode.org and/or mailing list).
