FM Synthesis by Adrian Frost

Part 2 - Basic Synthesis and a bit of practice In last month's article on FM synthesis we took a very brief look at the beginnings of FM synthesis and I introduced you to the soft-synths that we'll be using throughout this series. This month it's time for some basic theory and a bit of practice using Concrete FX's "Feed" synth.

If you do further reading on FM A warning right here and now, we're synthesis you might sometimes find not going to be delving much into the that the term "operator" is used to mathematics of FM synthesis, others describe a combination of two have already done that work and oscillators and an envelope, however produced better write-ups than I could we'll stick to the one to one ever hope to produce. My aim in these correspondence between oscillator articles is to give you enough useful and operator that is most commonly knowledge of FM synthesis that you'll used. It helps though to be aware that be able to create the sounds you want Building Blocks - Operators operator is sometimes used in this to create for use in your own music. If way. you do want to look into the One thing becomes very clear when theoretical and mathematical side of you start digging into FM synthesis, a Last month I mentioned Yamaha's things, which is fascinating in its own lot of the elements that go to make up DX7 - the first widely available right, I highly recommend Dr. John an FM synth have different names commercial FM synth. All of the DX7's Chowning and David Bristow's "FM compared to the bits and pieces you'll operators produced a basic sine wave - Theory and Applications: By Musicians find on a subtractive synth. Despite and that's all. Many FM soft synths for Musicians". Unfortunately this this these two types of synthesis these days offer a whole range of book is currently out of print but can actually rely on at least two of the oscillator/operator waveforms but often be picked up from online book same basic building blocks - those retailers at a reasonable price. we'll always be using sine waves being Envelopes and Oscillators. We'll during this series. Why? Firstly, that's take a look at envelopes in a few what Yamaha did on the DX7 and they Right, back to our operators. To do minutes, thankfully they use the same didn't come off too badly. Secondly, any type of FM synthesis you need at terminology as in subtractive because it makes things simpler and, least two operators. One on its own is synthesis but they do perform a thirdly, you'll be blown away by what not much good. This month we'll be different function. For actually making you can do with just a couple of sine looking at basic synthesis - what can sound, FM synths use oscillators, waves. be done with just two operators - but except that they are called in future articles will be diving into "Operators". complex synthesis to see what
