Temporal representation of a “saw tooth” waveform reproduced by TAE®
What’s more, the hardware analog oscillators were unstable. In fact, their waveform varies slightly from one period to another. If we add to this the fact that the starting point for each period (in Trigger mode) can vary with the temperature and other environmental conditions, we see why vintage synthesizers have such a typical sound.
TAE® reproduces the instability of oscillators, bringing a fatter and “bigger” sound.
1.3.3 Direct Filter Circuit Modeling
Due to advances in computer processing power, Analog Factory 2.5 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 when the filter is in self oscillation mode, for both one of Arturia’s virtual instruments and what it is emulating. These harmonics are characteristic of hardware synthesizer filters and are due to the
