Farey Sequence Tables for FM Synthesis


The choice of Carrier:Modulator (C:M) frequency ratio is an interesting area of research, because it is one of the fundamental aspects of FM programming. Although I mentioned the classic book by Chowning & Bristow in the recent Matrixsynth NYZ DRN4 DECLASSIFIED, space and time didn't allow me to mention another classic text by Barry Truax: Organizational Techniques for C:M Ratios in Frequency Modulation. If you're interested in FM programming, and you don't mind a tiny bit of maths via the Farey Sequence, I highly recommend it. If you want to dig deeper I've made some useful tables for FM synth programmers in this post. There's also a handful of youtube FM synthesis vids at the end.
