How can I use Dorico with that library :
Dorico has no problem working with Kontakt Player, so I’d guess it will work fine.
Of course, you will need to define expression maps to connect the Dorico playback techniques to the Berlin Orchestra instrument articulations.
I have the complete Kontakt current Cinematic Studio libraries which work fine under Dorico even if occasionally you need to adjust the timing. All you need to do is to look up the keyswitch/CC mappings from the library documentation and create the Expression Maps accordingly. The Berlin Inspire libraries appear to be fairly light and cut down versions so with luck shouldn’t be too hard to programme. There are a few Orchestral Tools users here, I think, who could perhaps give tips
