• @Golgoth's patch for FM Rhodes got me thinking about phase modulation in a different way, more like a sawtooth phasor and a sine wave going into a wavefolder. In a sine function, there is no need to use a fract(x) or mod(x) expression.

    You just feed the sin(x) a wiggly sawtooth wave that is the sum of the phasor a bipolar sine wave and the rest sorts itself out.

    Then I was reading the above interview with John Chowning about how he used transcendental numbers as modulator to carrier frequency ratios and the square root of two was particularly good for bell tones. So I ended up putting the two thoughts together and a little to my surprise it sounds pretty bell like with only two operators. Attached is the patch I made.

  • Very nice I love the way it sounds, especially when you change the envelope settings into the PM input of the second oscillator - very cool tones!
