It’s not uncommon for plug-in developers to build on previous successes. Often we’ll see existing features enhanced and rolled into their new releases.
In the case of Blue Cat Audio, not only do they build on existing plug-ins, they actually wrap them up entirely in their new offerings! Welcome to Axiom. A hybrid that comprises Patchwork, Destructor, and Late Replies, all rolled into one powerhouse multi-effects processor and dual amp simulator; designed specifically for guitars and basses.
