Shuriken has released CopyShop, a freeware FSU effect plug-in.
This my friend is a what you would call a FSU VST, all it does is chopping up buffers and plays them back. of-course you can choose the length of the piece of audio played back and when to apply it.
CopyShop is available for Windows and MacOSX.
Visit Shuriken for more information and a link to download CopyShop, a manual (.pdf format) and a video showing how CopyShop works.
