You should read Urs Heckmann's (u-he) blog on the topic._leras wrote: Sun Sep 04, 2022 8:19 pm I don't think people actually calculate sin though, they'd have a lookup which would in essence be the same as a waveform/sample of sin.
To oversimplify a complex topic, Urs doesn't literally calculate a sine wave or look it up. He actually calculates the behavior of analog circuit components that create an analog waveform. Hence the term analog modeling.

"My understanding of analogue modeling in the most simple terms is this: In analogue modeling we use formulas that deal with voltages and currents. These formulas are furthermore based on the understanding of the electronic components used in a circuit, and how they're wired up."
