Following up on the success of the popular Virus, Access unleashed an upgraded model in 1999, the Virus B. The original Virus A had 12-voice polyphony, but the new OS in the Virus B doubles the polyphony from 12- to 24-voices and the oscillators, from 2 to 3 per voice. The new OS also added an enhanced programmable 32-band vocoder. There are now up to 82 simultaneous effects, a retro-phaser (6-stage stereo phaser with 24 filter-poles), chorus/flanger, ring modulator, multiple forms of distortion, an analog boost algorithm, and an envelope follower. Up to five FM (Frequency Modulation) modes are also on-board now and many new sounds have been created for this bigger and better version of the Virus.[1]
