Since you have a 64bit OS then I am going to assume that your Magix Samplitude is also 64 bit. If not them by all means get a 64 bit DAW as it will make a huge difference with Kontakt. Why? Because the best Kontakt sounds and/or a number of Kontakt sounds will take a lot of ram and with a 32 bit program you can only access about 3.5 gigs of ram total, including all programs and data/sounds. There is a work-around with jBridge but I found it to be a PITA, YMMV.

Herb as already answered your PVR question so my question to you is do you know how to set up Kontakt as a VSTi? It is the same for 32 bit or 64 bit but hopefully you have a 64 bit DAW.

I hope this helps.

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
