Shuriken has released Shredder, a sampler designed to be easy to use and fun to play with.

From the Shredder page:

Shredder samples on your command (via MIDI notes on) and replays (also via MIDI notes) in different modes (choosen by the user) and tweakable pitches (tweakable by the user that is).

Check this YouTube video for a better understanding of what this plugin does. There’s also a manual available.

Shredder is released as donationware for and you can download a version for Mac OSX and Windows.
