🎹 TDL Synth Chat – FM Synthesis Deep Dive with Matt Atkinson!

This week on TDL Synth Chat, I'm joined by Matt Atkinson, an FM synthesis enthusiast and longtime Yamaha DX collector. Matt has owned almost every DX synth over the years — from the DX7 and DX9 to the V50 and beyond — and in this episode he shares stories, history, sound design techniques, and a full demo of his Yamaha V50 custom sounds.

If you love FM synthesis, Yamaha DX gear, the V50, or just retro synth chat in general, you're going to enjoy this one!
