In this Multi/Poly tutorial, I walk through my full sound deconstruction process, taking a preset from the Cherry Audio P-10 (Prophet-5 style synth) and recreating it step by step on the Korg Multi/Poly.
This is a technique-focused video rather than a preset dump. The goal is to show how to listen to a sound, break it down into layers, oscillators, filters, envelopes, and modulation, and then rebuild it on a completely different synth. While I’m using the Multi/Poly here, the same approach works on almost any synth.
The sound I’m recreating is the P-10 preset “Fat Sweeper”, a layered, resonant patch with filter movement. I start with no prep work at all and build everything from scratch, explaining my decisions as I go — including layering strategies, oscillator sync, filter envelopes, and when to simplify or optimise the patch.
This isn’t an exact clone — and that’s intentional. The focus is on the thinking process behind recreating sounds so you can apply it to your own synths and favourite patches.
If you enjoy this format and want me to deconstruct other classic synth sounds, let me know in the comments.
