I read that add as $199 is the introductory one year price. The real price is $360 a year.

As I say previously "If so here is what I would do. Forget about changing sounds in BiaB as you are working with the same low end GM sounds. Drag and drop the BiaB MIDI tracks to Mixcraft and learn how to assign your Kontakt player to each and every track. For now add a different Kontakt player to each track. Then assign different sounds to each track via the player. It isn't that hard. If you are having difficulties let me know and I will DL the Mixcraft demo and try it myself; or maybe some here who uses Mixcraft can help."

I would do this prior to purchasing anything else. Once you get this concept down the explore other avenues. Personally for you I think Kontakt is a much better purchase then EastWest; but wait for the full Kontakt to go on sale if you want/need it for some presets. Kontakt has a lot of third party presets available, even for the player. This should satisfy your needs for many years, at least it has mine. Kontakt, a few specialized VSTis, and a number of free VSTis are my main MIDI sound sources. I do have EastWest's Symphonic Choirs that I occasionally use but now Kontakt has some choirs that are as good as if not better now. YMMV

Doc-take it easy John this is just a sharp scalpel. It will not cut deep so don't worry.
Me-I'm not John
Doc-I know, I am!
