Thank you for a good series of articles and some great insight into the inner working of FM synthesis in general. I have never owned one of the original Yamaha's, but i have been using the awesome Dexed VSTi plug in, that is modeled after the DX7 for several years now. And I am planning on purchasing a Korg Opsix for its FM capabilities. But for someone that has only been on the learning-by-experimenting end of FM synthesis, your articles are a great insight into the theory behind it all.
