Tutorial: Karplus-Strong Synthesis in Unreal Engine 5.7

In response to positive feedback on some of my synth designs I have decided to start a tutorial series on synthesising sounds for procedural music in Unreal Engine's MetaSounds. This first lesson starts with the basics of string synthesis, we will be using this basic synth as the foundation for a few videos going forward. I have tried to explain the method in a way that makes sense to anyone trying to synthesise strings this way outside of the realm of game design! I hope anyone out there new to either MetaSounds or building synths finds this useful. Let me know in the comments if there is any area you would like to see explored further.
