I have no clue. When I sample I use an ASRX and I'm able to either
a) assign individual samples to which ever pad I choose or
b) take one sound and assign it to the whole keyboard with the pitch changing accordingly with each pad.
I have been wondering myself if there is a way to do option b with software.
Get Recycle so you can set cuepoints and then load it to Dr.Rex, or if you want a sample with pitch spread over the keys, load it up in nnxt or nn19 as a sample.
