The Most Comprehensive Synthesis Education Online
Synthesizer Guru is the deepest, most thorough synthesis course available anywhere online. Across 43 modules and 7+ hours of video, you will build a complete, professional-level understanding of how synthesizers work — not just how to use one preset on one instrument, but how to think like a sound designer across every major synthesis type.
We start where it all begins — the physics of sound itself. From there, the course takes you through subtractive synthesis, FM synthesis, wavetable synthesis, and additive synthesis. Each type is taught from the ground up, so you understand not just what to do, but why it works. By the end, you will be able to recreate virtually any sound you hear.
This course is built around real instruments. You will get deep inside the Minimoog, Juno-106, Prophet-5, OB-X, MS-20, and DX7 — the synthesizers that defined modern music. Understanding these instruments gives you a framework that applies to every software synth you will ever use.
How I teach
Every lesson in Synthesizer Guru is built around real hardware and real demonstrations. You are not watching theory slides — you are watching an instrument being played and programmed in real time, with every decision explained as it happens. This is how professionals actually learn synthesis, and it is the only approach that sticks.
Claudio's teaching philosophy is rooted in systematic understanding. Rather than teaching you individual patches on individual synths, the course builds a mental model of synthesis architecture that transfers to every instrument you will ever encounter. Once you understand how a filter envelope shapes a Minimoog bass, you understand how it works on every synthesizer ever made.
Claudio's passion for synthesizers spans four decades — from hearing his first Moog record as a teenager to owning and playing his 1972 Minimoog Model D today. That depth of experience informs every lesson. Students who complete the full course earn a Diploma in Synthesis, a certification that signifies professional-level knowledge and a genuine command of the art.
