Our testers have confirmed that Electra 2.1 and Saurus2 work in Protools with the Blue Cat Patchwork adapter.
"I just tested the demo version of Blue Cat Audio's PatchWork v1.7 which works as Standalone or as a plugin.
With the available 64-bit AAX plugin of PatchWork i was able to load and play Saurus 2 and Electra 2.1 inside Pro Tools 11.3.1.
Here is a screenshot:
