Welcome To MFOS, Your Synth-DIY Headquarters. What is synth-DIY? Synth-DIY is just what the name implies. Synthesizer Do It Yourself. Many people, like me, grew up in the dawn of the analog synthesizer age (Moog, ARP, Oberheim, Buchla, RCA, EMu, Fairlight, PAIA and many others) and although we may have really wanted our very own analog synthesizer with dozens of knobs and switches they were w-a-a-a-y out of our reach financially. Now many people with a modicum of electronic skills and a renewed interest in analog synthesizers are discovering that with a schematic, a PC board and some electronic components they can do it themselves!. MFOS' mission is to help people realize their synthesizer dreams. We do this by providing analog synthesizer projects with complete schematics, assembly drawings and professionally manufactured PC boards. If you already have electronic skills... welcome! If you would like to learn more about electronics or analog synthesizers then try these links: How can I start learning about electronics?, Analog Synth 101 and/or The MFOS Book Store. It's never to late to develop a new skill, reignite an old passion or exercise your creativity. Keep imagining, keep inventing, stay ingenious.
