Temporal representation of a “saw tooth” waveform reproduced by the Jupiter-8V
What’s more, the hardware analog oscillators were unstable. In fact, their waveform varies slightly
from one period to another. If we add this to the fact that the starting point for each period (in
Trigger mode) can vary with the temperature and other environmental conditions, we find one of
the characteristics that contributed to the typical sound of vintage synthesizers.
TAE® reproduces the instability of oscillators, bringing a fatter and “bigger” sound.

Direct Filter Circuit Modeling
Due to advances in computer processing power, the Jupiter-8V can now employ direct filter
modeling techniques to achieve unprecedented accuracy in the emulation of a hardware
synthesizer’s filter. By modeling the operation of the individual hardware components of the filter
circuit, the warm nuances synonymous with analog sounds are recreated. This graph 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, for both the Arturia Jupiter-8V and the Roland
Jupiter-8. These harmonics are characteristic of the hardware synthesizer’s filters and are due to
the non-linear behavior inherent in 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.
