Bob NystromLittle known fact, but when John Chowning first discovered/invented FM synthesis, it stood for "fuckin' mental synthesis". Yamaha made him come up with some mathematical "frequency modulation" nonsense instead in order to sell DX7s in regions with profanity laws.
dr2chase@munificent Studied FM modulation in the signals/communication class senior year in college, cannot tell if this is true or a joke, it's consistent with the math. "The spectrum is a Bessel function? WTF?"
