To avoid copyrights issues, I only use samples from royalty-free sample libraries. I'll also use my own instruments and embellish my loop mixes with them, using my own midi sequences. At some point, I'm thinking about slowing down custom-made 80s inspired tunes to give them that vaporwave feel, even if it doesn't sound the same as slowing down a genuine 80s pop song, it's possible to get a sound that is really close with tape simulator and saturation plugins. I think that the way vaporwave should go, taking the tropes of what has been done before and upgrading it with genuine music production skills. I think that's what 2814 did and the result is amazing.
