The largest family of plug-ins in the ISP is the Blue Cat line: nineteen modules comprised of six dynamics processors, six EQs, six FX units and a channel-strip. The groups of six are also available in sub-bundles that are also massively more expensive than what they can be had for during a sale. The Blue Tube collection is now at version 3 and that version was introduced in 2006. I could not track down the date of the appearance of earlier versions. However, I did find a forum post from the developer, the late Bernie Torelli, who wrote that version 3 was a complete ground-up redesign of the collection, both internally and externally.
