As far as cakewalk, r_baeyans is probably right. Depends on wha tyou are trying to do with the samples. If you are triggering simple one-shots, dropzone might do the trick. If you are going to attempt to build multi-sample patches you will need to learn more about the sfz format or go with a third party sampler like Kontakt. If you are on a budget, there are freeware samplers tha twork in sonar. So far i have tested Short Circuit.
