There are seperate sets for sfz, kontakt, reaper and tx16wx.
Only my reaper drumkit ( MegaReaper) is the one with 127 layers and 2 to 4 round robins.
Why ? Because im mentally unstable ..but seriously, play it on really responsive drum pads and you will know why.
There are other kontakt, TX16wx, reaper and sfz versions have a much saner and more realistic 32 velocity layers with 6 + round robins , which is what may be what you are looking for.
All the goods are here :
