Are you looking for wave files? What kind of sampler do you have? If you're looking for commercial sample developers, I would suggest looking at pro-rec.com However, many commercial companies do not seem to do this kind of straight-forward sampling. The last time I checked, I don't believe that they had Mo' Phatt sounds (a lot of older Roland and Korg keyboards).
If you don't go the commercial route, I may have another solution for you. I recently sold my Mo' Phatt in order to free up some money for another studio purchase. I have Gigasampler, so I sampled most of the sounds from my Mo' Phatt before I sold it. The sounds are still in raw wave form, since I haven't had a chance to edit the samples for preparation to Giga format. The samples are 24-bit/44.1, one-shots and multisamples. If you would like them, I could send them to you on CDRs for $10. It would cover the cost of CDs and postage and handling. Let me know if this works for you.
