Session Loops sampled Simon Phillips drumming for some loops they were producing and decided to provide the individual hits as a drum kit. They provided the samples and a Battery1 mapping of the kit. I've used the same layout of the instruments but I've adjusted the velocity layers in places to match sfz better.
Once you've downloaded the samples, save the sfz format file (3Kb) into the same folder.
According to the Session Loops page, the samples are royalty free and free for redistribution.
