Its got nylon and steel string acoustics, plus a hollow body electric with both the acoustic sound sampled with a mic and the electric sound recorded direct (which you can mix in real time via midi control).
It doesn't have any pre-recorded chord strums.. through Kontakt 2 scripting it has very nice chord strumming modes where it can detect chords that you are playing, or you can voice a chord any way you like, and then strum them up and down via 'strumming keys'. Its similar to Real Guitar's method and is the most versatile strumming system because you are not locked into whatever strums the developer decided to record.
Thanks for the response. This is sounding more and more like what I'm looking for.
Also, for what it's worth, someone told me to look at the CHG site for strumming samples (the examples I was listening to at another site didn't include strumming).
The strumming are really good, you can tweak a lot of stuff; it takes a bit of work to get really comfortable but not much considering what you can do .To me overall, it's the best acoustic/electric guitar library.
