Video Transcript

"In the last clip, we alluded to something called FM. FM stands for Frequency Modulation. The frequency we were discussing in wave form is how fast the waves go from all the way to the bottom to all the way to the top. Frequency modulation means we're changing that speed. Now normally what this would do is it would actually change the pitch. The frequency modulation operates in a very low and very subtle scale; it does a lot more than change the pitch if you wanted it to. It also changes the basic sound of the sound itself. I'll show you how to mess with it. This knob right here, right next to OSC 2 is labeled very clearly FM. FM- frequency modulation can be controlled by that knob. If I have it all the way off, it already sounds like a basic sound wave. If we have it all the way on, it has that strange sort of grainy sound coming back. This is because when frequency modulation is all the way up and is modulating the frequency as high as it can, quite obviously, what this is doing is that the wave form is being changed and is changing from being a sign wave to being something not quite a sign wave, but not quite anything else. This is a frequency modulated sign wave."
