[Yes you can use it as a sampler, but it is not a good one. It is more like a gadget but you can sample a loop into the pad an use it later. You have no floppydrive so you have to store everything in your pc. Its a funny thing and i used it together with another keyboard.
How to use: there is a button RECORD which you have to push during playing. It records that sequence. Afterwoulds you can play it again.
Best regards.
