I've used Sibelius 3-6 with GPO and the subsequent built-in orchestra on and off for ten years. Loading Garritan sounds and driving them from the notation has always been relatively straightforward, even years ago.

Now I need to load half a dozen bluegrass instruments including at least one (the dobro) that isn't in the Garritan pantheon. How do I load a third-party sample library into Kontakt 4 as a plug-in so the sounds will run within Sibelius? The Kontakt Getting Started and Reference documents are grossly inadequate to explain this process. The library in question is Whole Lotta Country, marketed by Big Fish Audio, who unhelpfully provide zero documentation. Am I missing a Native Instruments how-to manual somewhere?
