I'd like to extract only certain slices from a REX file and assign them to contiguous keys on my keyboard; could anyone please tell me the easiest way to do this? (I'm using a 1:30 REX split into ~40 slices, of which I only want to use 10 or so)

If I just load the REX file into NN-XT, it automatically uses every slice, and it's time-consuming to rearrange the files in the sampler afterwards...

thanks!
