Access is well-known for creating some of the most popular modern synthesizers. Their Virus virtual analog synthesizer was one of the first synths to give virtual analog technology a good name.
The Virus synth is in its third incarnation, as the Access Virux C. The awesome Acess Virus KC puts the magic of the Virus engine in a 5-octave semi-weighted keyboard, with aftertouch. Another cool variation on their VA technology is the Acess Indigo 2. It’s a portable keyboard with a three-octave range, but the same synth engine as the Virus.
Their site has the full low-down on all their equipement, but isn’t as exceptional as their equipment.
