Here's a library with sample Drag'N'Drop (up to eight at a time) for the Free Kontakt Player. It might take a while for Native Access to recognize the provided serial but it downloads fairly rapidly, so be patient.

It is DND and, surprise, also accepts ncw files. That opens up virtually all of your Kontakt/Retail libraries as sample sources to play around with---something that may not be possible with VSTs of similar ilk. Not the ultimate, full-featured and deeply-tweakable multisample tool but quite nice in its own approach. No problem with soundscapes, underscores, atonal pads, etc. Melodic instruments are another story and it doesn't seem like the sounds are, or can be, mapped to multiple keys all across the keyboard. Still, a pretty neat library.
