Interesting. I agree that the article is an exaggeration. It could be argued that the DX7 had a significant negative musical contribution. Oodles of sounds at the expense of musical expression. The musician became alienated from the process of making the sound. The keyboard player's job moved from playing the piano or organ to coming up with all the accompaniment parts that aren't guitars. And the DX7 was way too dif…
> FM synthesis, as such, was not new. The Buchla synthesizer featured it in the 60's. But the critical feature of FM synthesis that made it usable as a musical element was linear FM. Early synthesizers (like, I presume Buchla's) sported "FM" but it was exponential due to volt/oct. > John Chowning refined the concept, moved from frequency to phase modulation, and brought FM into the digital realm. ?? Chowning's paper…
This is true today using something like the Chamberlin form for a state variable filter. I don't think that level of optimization had been discovered yet in the DX7 timeframe.
Also, for adequate quality you want to oversample at least 2x, preferably at least 4x.
And 16 bits usually won't be enough headroom in a digital filter for good audio quality. Too much truncation.
