FM Synthesis

Frequency modulation refers to the modulation of one waveform by another waveform, which results in a new, more complex waveform.

Operators

The waveforms used to create the FM sound are called operators. You can use up to eight operators. An operator can either be a carrier or a modulator.

Carriers

Carrier operators send their signal to the output, that is, their signal is audible.

Modulators

The signal of the modulator operators is not sent to the output, but is instead used to modulate the signal of the carrier operator.

Algorithms

The combination of the up to eight operators forms an algorithm. The algorithm defines how many carriers and modulators are used, the order in which they are executed, whether operators feed their signal back to themselves, creating feedback connections, and more. You can either select one of the preset algorithms or create your own algorithms.
