Final update - the new replacement libraries actually have a fair bit of new stuff in them - this is all free as well- You just have to re-register with the new serial number they give you.
Had contact with Magix support a fwe time lately and have always received very quick, polite and helpful replies.
The Sampler engine seems to be quite mature and very useable.
Have not really explored it enough to see if you can use different formats - I think the answer to this will be no.
Otherwise I can see me using this often and I shall be on the look out for what they release in the future library wise
