Access | Virus A


The Access Virus is a desktop synth-module. It quickly became a very popular and favourite synth with its aggressive analog sounds. It's got knobs, analog synth sounds and drums and a whole lot more. The Virus uses physical-modeling to re-create analog sounds. The Virus has a punchy and clean analog sound that can give you anything from low sub-woofer blowing basses to overdriven lead lines. The module is laid out with a very intuitive design that even old-school synthesists will feel right at home with. It has 32 knobs and 27 buttons, all of which allow tweaking in real-time. With 12 note polyphony and 16 multi timbral parts, the Virus is all you need to create complete and vibrant electronic music tracks.

Later when the Virus B came out, the original Virus became commonly referred to as Virus A (Even Access calls it Virus A on their website)

Velocity 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. Aftertouch 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.
