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 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 DSP processing power, Origin 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
