Can anyone tell me if its possible to rewire Reason and Sampletank?

Would be really cool....

If not, is there any way to work together with these 2 Programms in a easy way?

You can get a DAW (cubase, ableton live, acid, protools) and then use rewire for reason and just load up the vst sampletank. if you're strapped for cash or dont want to get it illegally then there's a free DAW called reaper.
Here's the link

I got Magix Samplitude. Must work, or?

As long as it supports rewire and vsti instruments. It should work
