I have them in Rapture Pro Factory Library bank for both Rapture Pro and Rapture Session - about 50 of them in PolySynth subcategory type. You could search for "Drone and Strings". For Rapture Pro, I think they may be installed by the early release Rapture Pro 2.0.5.77 in Command Center. I'm still wondering what's going on with this release becoming official. For some reason they released the Rapture Session version 2.0.5.77 but are still holding back on Rapture Pro. However, since some reported that the early release of Rapture Pro 2.0.5.77 is now working ok, I installed it. It's working fine for me and also seems to load patches much faster, which I find very beneficial.
This is the post about the Rapture Pro early release I was referring to:
