Sound Design Episode 2 | The FM Synthesis Revolution

Описание: Unlock the secrets of Frequency Modulation (FM) synthesis, the technology that defined the sound of the 80s and continues to power modern electronic music. In this video, we dive deep into the history, the math, and the "digital tricks" that make FM one of the most powerful sound design tools in your arsenal.

What You’ll Learn:
• The History of FM: Discover how John Chowning at Stanford University stumbled upon FM synthesis in 1967 through an "ear discovery" while experimenting with extreme vibrato.
• The Legend of the Yamaha DX7: We explore how Yamaha licensed Chowning’s patent to create the DX7 in 1983—the first commercially successful digital synthesizer that moved electronic music away from analog subtractive methods.
• The Secret of Phase Modulation (PM): Did you know the DX7 isn't technically "true FM"? We explain why digital synths actually use Phase Modulation (PM) to maintain pitch stability and keep your sounds perfectly in tune across the keyboard.
• Core Concepts: Learn the difference between Carriers (the oscillators you hear) and Modulators (the ones that shape the sound), and how Algorithms act as the routing map for your patches.
The Gear We Mention: If you want to start designing your own FM sounds, check out these industry-standard tools:
• Dexed: A powerful, free emulation of the original DX7 that can even load vintage patches.
• Native Instruments FM8: The modern king of matrix-based FM routing.
• Xfer Serum: While famous for wavetables, its "FM from B" warp mode is a game-changer for aggressive bass design.
• Elektron Digitone: A modern hardware powerhouse that makes FM synthesis intuitive and performance-ready.
