How to Make the Billie Jean Synth Sound on a Virtual CS80

In this video, I break down how to recreate the iconic string/brass synth sound I created for Michael Jackson’s “Billie Jean” using a virtual Yamaha CS-80. If you’ve ever been intimidated by CS-80-style synths (or plugins like the Cherry Audio GX-80), this tutorial simplifies everything into clear, usable steps. We’ll walk through the fundamentals of analog subtractive synthesis—VCO, VCF, and VCA—showing how to build expressive string textures and punchy brass layers from scratch. I also demonstrate how to create the “fake reverb” effect using envelope shaping, inspired by sounds from Stevie Wonder’s work on the GX1. Whether you’re using a CS-80 emulation or any synth like a Minimoog or ARP Odyssey, these concepts translate across the board. If you want to stop relying on presets and actually understand how to program your synths, you might find this useful.
