1.1.3. Direct Filter Circuit Modeling
Due to advances in computer processing power, TAE® 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.
The following graph shows a single example of direct circuit modeling in action. The peaks
represent the generation of harmonics at multiples of the resonant frequency when a
particular filter is in self oscillation mode. These harmonics are characteristic of hardware
synthesizer filters and are due to the non-linear behavior inherent to their analog circuitry.
Anomalies such as these add to the richness and warmth of the sound produced by the
filter.
But you’ll notice there are two lines on the graph: Those are the superimposed frequency
domain plots for both one of Arturia's virtual instruments and the hardware filter being
emulated. They are practically indistinguishable, both on the graph and to the human ear.
The direct recreation of this analog circuitry causes the same characteristics of the sound
to be present, thus giving the user a truly analog sound.
So here’s the bottom line: when you bring together a bunch of music lovers who also have
a deep understanding of the characteristics of electronic circuits, you wind up with Arturia.
And Arturia now offers you our most impressive software model yet, the Mini V.
We take great satisfaction in knowing this great synthesizer will help you explore previously
unknown musical territory.
