preenfm2 and preenfm3 / general FM synthesis question
« on: March 09, 2021, 04:21:37 PM »
Hi All,
This is my first FM synth with non-sinusoidal operators. I am trying to wrap my head around how it impacts the harmonics when you have something like a sawtooth wave as a modulator. I wondered if you all have general advice for how to use / think about other wave forms as modulators? I'm guessing there are common tricks/uses for them?
For example, let's say I have a simple 2-operator patch with a sawtooth wave modulating a sine wave at a 1:1 modulator:carrier frequency ratio. A sawtooth wave has every harmonic above the fundamental with progressively decreasing amplitudes. Am I then right to think of this modulator as a bunch of sine modulators in parallel with frequency ratios of 1:1, 2:1, 3:1, etc. and progressively decreasing amplitudes?
