The important part of ROG's reply was that PT also has the same 'instrument definition' files. PT calls it a patch map. Once loaded it can show your synth's patches.
You can find the one you need here -

There are directions in support, inside the Patch Map file (in the comments) and I think inside the manual too.

Basically:
Download the correct Patch Map, rename your existing Patch Map files (to preserve them), and then copy your new ones to your PT folder. It's easier than it sounds in the directions.

I do not work here, but the benefits are still awesome
