Also, if you have Kontakt, you can use Kontakt guitar libraries like the ones made by Orange Tree Samples (best in class IMHO), Indiginus (also superb, but less expensive) or I'd imagine even the bundled Kontakt Akkord guitar, all of which have strumming engines/ patterns, to -- like the RealGuitar technique I've mentioned -- send their output as midi which can drive other VSTis.
