Welcome to a new series I'm kicking off that is going to take a long look at frequency modulation, how it works, and how to use it. This is a big topic that often gets shortchanged in terms of real explanation, so I'm going to take it a step at a time.

In this video I'm going to start slow with LFO rate modulation so we can get a sense for what is happening to the Carrier oscillator, and to explore the controls we have and what they do.

Part of this effort as well is to shine a bit of light on the original paper on FM by John Chowning. There's a lot of interesting stuff in there that I never knew about, and I've been programming FM synths since the 80s!

Get ready, we're going deep.

Here's a link to John Chowning's paper: https://web.eecs.umich.edu/~fessler/c...
