FM synthesis basics and signal flow

So let's take a look at the EFM1 interface and signal flow. EFM1 is a little bit different than what we have seen so far, because it's an FM synthesizer. So FM stands for frequency modulation. So it's going to react a little bit differently and the signal flow is going to be different than the subtractive synthesizers that we've taken a look at so far. So what we have is a Carrier oscillator that's going to generate sine waves, and we have a Modulation oscillator over on the left side. The Modulation oscillator is called the Modulator. What that's going to do is send pitch modulation information to the Carrier, and the way that we control the intensity of that is with this FM Intensity dial that's in the center.

So basically what's happening is a really fast pitch modulation. That's how we are going to generate all the different tones in EFM1 is by pitch modulation or frequency modulation and controlling the amount of intensity. If we look down below in...
