In 2001, the Virus Rack was released. This module retains most of the features through version 4.0 but sacrifices polyphony and an oscillator. This was to make the Virus significantly more affordable. Polyphony has been reduced to 16-voices but multitimbrality is still 16-parts. Instead of four, there are three oscillators per voice (two main oscillators plus one sub oscillator) and only 1 FM mode. Otherwise it has all the same great features as the Virus B.

||As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key.
||Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
|Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
