Better reproduction of analog sounds with direct filter circuit modeling

Arturia emulate both the classic Prophet 5 and the lesser-known Prophet VS synthesizers in their latest software instrument. Arturia's previous soft synths — the Minimoog V, Moog Modular V, ARP 2600V, and CS80V — have been generally well-received by reviewers and players alike, so Prophet V joins a respected family of recreations of vintage instruments. These videos are designed for new Arturia Prophet V users. Tyler begins with a quick history of the Prophet synths and reveals their user interfaces and basic operation. He then starts with the prophet 5, showing how the instrument employed subtractive synthesis, which is common among analog synthesizers, but this instrument was a classic for a.

TAE® reproduces the characteristics of analog filters in the digital domain.

Let’s take our Prophet-V for example. Due to advances in computer processing power, Prophet-V can employ direct filter modeling techniques to achieve unprecedented accuracy in the emulation of the original 4-pole low-pass analog filter. By modeling the operation of the individual hardware components of the filter circuit, the warm nuances synonymous with the original analog instrument are recreated.

This graph is a frequency domain plot that serves as just one 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 the virtual (blue) and original (red) instruments.

These harmonics are characteristic of the Prophet 5's filter and are due to the non-linear behavior inherent in its analog circuitry. The generated harmonics add to the richness and warmth of the sound produced by the filter. As a result of the direct modeling of the analog circuitry the same sonic characteristics are present in Prophet-V, thus giving the user a truly analog sound.
