LividSampler 

This comes in standalone, plugin, and source versions. This was done in Max/MSP 4.6 (the old one) so it can be exported it as a VST/RTAS/AU plugin, using their dying Pluggo technology.

A simple and extremely easy to use sampling application lets you easily assign and edit sounds for each button in the 64 button grid of the Ohm or block controllers. The standalone will automatically detect the controller - no hardware setup or MIDI learn necessary. Plug in takes notes 0-63 to play each sound.
