WiVi instruments are the ultimate proof that samples are slowly but surely getting obsolete. Gone are the days when 500GB hard disk and 2GB of RAM wasn't sufficient for running a full symphonic orchestra. Well, that's not entirely true yet, but it is true for brass and woodwinds. The rest of the instruments are still waiting to be released. ATM, I have the full WiVi brass and the flutes from the woodwinds.
