I recently had the pleasure of creating an official demo for Embertone's fantastic library "Joshua Bell Violin." In a nutshell, the library's sound is remarkable and distinctively Bell-ian, and the instrument is flexible enough that you can get great results with both live performance-out-of-the-box and with detailed performance shaping. There are LOTS of parameters you can control with this instruments. Take a look at the walk-through screencast above for a better explanation of what I'm talking about. Oh, and go to Embertone's website to find out more about the instrument.
