The debian packages install to /usr/local/lib/vst (or vst3 or clap) so I moved them to
.clap, .vst, and .vst3, and tested the clap version.
They require ROM files from the discontinued Access Virus B or C models, which are widely available for download, and not contested by Access, since they don't make or sell those models any more, and public awareness may actually convince people to buy their current products. Put the ROM .bin file by the plugin. There will be over 700 categorized presets in banks A through H, not including some that are found in more than one bank. In the numbered list on the left, right-click the number to choose the midi channel, so multi-timbral is easy to arrange.
