If you're working with loops, grooves and samples, ReCycle let's you 'slice up' a section into it's component beats, then play around with the pitch and tempo. It creates REX files, so you can import them direct into any program supporting the format (such as Reason's 'Dr. Rex', Cubase VST, etc.)
ReCycle! 2.0 now has support for Stereo files, and introduces Preview Listening and Real Time Effects.
It also supports an extended list of samplers.

Here at Sonic Towers, Nick's been chomping at the bit waiting for this one - and the first stock to arrive here was on the day he left for his vacation, so if you're quick, you could grab a copy at the Shack and play with it before he does ;-)

I guess I've been trying to recreate a Korg Electribe all this time..
