Phil, you could buy an external sampler and use it with the XP-60. If you want hardware sampling the first one that comes to mind is the Boss SP-303. I think it goes for $299.00 It's a decent sampler and excellent for someone wanting to get into sampling. Of course you can also search Ebay and look for older models as well.
