I am in the middle of investing in a couple of instruments based around the Kontakt player (XSample Chamber Ensemble and Ethno World 4 with free upgrade to version 5). Hopefully this works in Logic 9 but I don't actually know. Another thing is, what about Kontakt 4 does that work with G5's or is it the same as Logic 9.1. I'm thinking the 64 bit compatibility is a problem but again I don't know. I plan to upgrade my computer as soon as the next MacPros come out but I wouldn't mind if the stuff would work now. It's my impression that there are many Logic users who also use Kontakt so I'm hoping some of them will enlighten me on this one.
