Access Virus A

Access Virus A Image

The Access Virus is a very cool, German made desktop synth-module. It quickly became a very popular and favorite 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 digitally re-create analog sounds. German precision got it right! The Virus has an incredibly punchy and clean analog sound that can give you anything from low sub-woofer blowing basses to overdriven 303-style lead lines! The module is layed 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 realtime. With 12 note polyphony and 16 multitimbral parts, the Virus is all you need to create complete and vibrant electronic music tracks!

With basic analog waveforms, from sawtooth to pulse with PWM, dual oscillators and filters, two LFO's with sample-and-hold and on-board arpeggiators, you'll find yourself in vintage synth heaven. The Virus can make convincing TB-303, SH-101 and other great bass/lead sounds, as well as a host of analog drum and percussion sounds. You'll also find an advanced ADSTR envelope, effects like chorus, flange, delays, and a very nice Vocoder! Every parameter is MIDI controllable making this a great tool for use in the studio.

In 1999, Access released a next generation model which they called the Virus B (making the original sometimes referred to as the Virus A). Following that came the KB (keyboard version), Indigo (Roadster version) and Rack (rack-mountable sound-module version). In 2002, an even more advanced C series was released including the Virus C, KC, Indigo 2, and Rack XL. A slightly 'hot-rodded' form of the original Virus A was also released in 2000 as the Digidesign Virus TDM plug-in for Pro Tools users, followed in 2002 by an Indigo TDM version. Viruses have been used by Astral Projection, BT, Überzone, The Crystal Method, Cosmosis, and Nine Inch Nails.

there's no reverb in the virus a, the effect are 4 chorus/flanger and 1 global delay with send for each part, so the specification here are wrong, someone can confirm?

I had one for a good while but after I got a real analog (juno) it just didnt so it for me anymore. I do miss the depth in programming and eventually buy the Xpander which it was modeled after but I'll never go VA again. I hate to be jerky but if you listen in person sided by side to raw unmodulated unfiltered oscillators real analog killis. In fact even when I was all about VA i was disappointed in this one after selling my JP8000 for it. The virus was nowhere near as 'lush'. Virus is great for deep programming crazie people. Ive also gotten some nutter sounds I'll never hear again from this bad boy. IT IS WHAT IT IS.

Yes, VNV Nation's "Empires" is made on Virus A, but with almost chiptune sound of this album it is a SHAME for Virus synths. Or maybe VNV Nation guys just forgot to enable unison mode on Virus.

This synth was used on VNV Nation's Empires album almost exclusively, Access might as well as sent out that CD as a demo of what this powerhouse can do.
