Actually Andi, the comment that the Cubase VSL Strings is not 100% compatible with Dorico seems rather flattering š.
I'm inclined to agree. Having worked out over the summer how to implement keyswitches in Finale, I had a bit of a head start working on the Dorico maps. First I looked at an import from the Cubase set, and found things like multiple instances of (say) legato referencing separate keyswitches. Rather than try to figure out why (also, there were combinations of terms that you can't* create or edit in Dorico) I set about making a set of my own.
Once you realize that, for Synchronized Special Edition, most sets are largely the same -- flute, oboe, clarinet, for instance -- it cuts down the time it takes.
