Depending on the setup you have, Reason has a nice interface for its NN-19 sampler ... You can choose to load a .wav, and then scroll through your one-shots in the 'choose file' dialogue ... with it set to auto-play them as you scroll through.

All you need now is a wireless keyboard and you can sit back hitting the down-arrow while your track is looping until you find something you like :)

It falls over a bit on large file-size samples though.
