Experts regard the Virus b, first introduced in 1997, as the virtual-analog synthesizer that comes closest to simulating its true-analog predecessors.

In addition to its unique and balanced sound characteristics, this exceptional synthesizer also stands out because of its tremendous sonic capabilities and the attention paid to its intelligent design.

The philosophy behind the development of the Virus was to create a synthesizer with a vast palette of sonic possibilities rather than simply simulating static analog circuits. This demand made it necessary to take into consideration the numerous very fine sound details that make an analog synthesizer or an acoustic instrument sound so alive.

The Virus' powerful DSP technology allows you to create these specific sound characteristics without being restricted by traditional analog limitations.
