synonymous with analog sounds are recreated. The graph below is a frequency domain plot as just a
single example of direct circuit modeling in action; it shows the generation of harmonics at
multiples of the resonant frequency when the filter is in self-oscillation mode, for both one of
ARTURIA’s virtual instruments and the one it is emulating. These harmonics are characteristic for
analog filters and are due to the non-linear behavior inherent to its analog circuitry. The harmonics
generated add to the richness and warmth of the sound produced by the filter. As a result of the
direct recreation of this analog circuitry, the same characteristics of the sound are present, thus
giving the user a truly analog sound.
