The Ultra Analog VA is a virtual analog synthesizer. With this product, we have not attempted to emulate a specific vintage analog synthesizer but rather to combine into a modern instrument, different features of legendary vintage synthesizers. The Ultra Analog VA generates sound by simulating the different components of the synthesizer through physical modeling. This technology uses the laws of physics to reproduce how an object or system produces sound. In the case of Ultra Analog VA, mathematical equations describing how analog circuits function are solved in real- time. The Ultra Analog uses no sampling or wavetable, it just calculates the sound as you play in accordance with the controls it receives. This sound synthesis method ensures unmatched sound quality, realism, warmth and playing dynamics. Before discussing the synthesizer in more detail, we would like to take this opportunity to thank you for choosing an Applied Acoustics Systems product. We sincerely hope that this product will bring you inspiration, pleasure and fulfill your creative needs.
