Note: Transportation Hard Case included on the sale

The Access Virus C (released in 2002 by Access Music) is a classic, DSP-powered virtual analog synthesizer. Housed in a durable chassis with wooden end-cheeks, it became an industry standard for electronic music genres like trance, techno, and industrial due to its thick tone and deep modulation architecture. 

Main Improvements Compared to the Virus B

• Polyphony: Increased from 24 voices on the Virus B to a maximum of 32 voices on the Virus C (depending on patch complexity).
• Modulation Matrix: Expanded to 6 sources and 9 destinations (up from the Virus B's smaller matrix), offering much deeper routing flexibility.
• Filter Options: Added a new Moog-style filter emulation mode (up to 36 dB/octave sloped options) alongside the existing multimode filters.
• Onboard EQ: Introduced a dedicated 3-band parametric EQ per patch.
• Effects Processing: Upgraded to handle up to 98 simultaneous effects (including independent phasers, choruses, distortions, ring modulators, and delays per part).
• Workflow & Interface Tools: Added a handy Undo/Redo function for patch editing, a Random patch generator button, and a dedicated Oscillator 3 On/Off hardware switch.
• Aesthetics: Swapped the dark/red color scheme of the Virus B for a sleek silver/grey look with rubberized/wooden side panels.
