For modulators however the level knob decides the amount of change it does to the carrier. For carriers this level knob controls the output volume. In this case Operator 2, 4 and 6 are the modulators.įor each Operator you can control its volume using the Out “Level”-knob. The ‘modulators’ then change the sound and timbre of each of these carriers.
So in this case Operator 1, 3 and 5 are the ‘carriers’ making up the audible output of your synth. The bottom row shows the carriers while the rows above show the modulators. Here’s what the default algorithm (nr 5) looks like: Then each algorithm connects the rest of the Operators in different configurations as carriers or modulators to make up your finished sound.
Whether an Operator is a carrier or a modulator is decided by the Algorithm setting. A modulator you cannot hear directly, instead it is used to change the tone/color/timbre of the carrier. A carrier is something that you can hear. Each of these Operators can be either a ‘carrier’ or a ‘modulator’. You can think of them as six different sine wave oscillators. Each Operator is a sine wave and is used to create a more complex waveform. The FM Synth is quite a complex synthesizer so read on to get a better understanding of how it works! Operators and Algorithms This is done using waveforms of different frequencies and amplitudes to kind of mangle, distort and change the sound into something more complex and interesting. This is very different than our other synthesizers like the Simple, which is doing subtractive synthesis.įM synthesis means that you create a complex waveform by modulating a simple waveform with another simple waveform.
The FM Synth is an instrument doing frequency modulation synthesis. The FM Synth is an online recreation of a classic Japanese FM synthesizer.
