Now as for a round robin...

When programming drums, a continual repetition of the same sample will sound unnatural, and, in extreme cases (drum rolls, or bass drum blast beats, for instance...) will give an effect known as 'machine gun'. A Round Robin will play a different sample for each successive note, sometimes each in turn, or, even better for most drums, randomly. This gives a more natural rendition. 3 or 4 RR's are enough for many applications (that's to say, 3 or 4 sets of samples to be triggered...), but 8 is good too..! If the samples are well recorded, the result is almost imperceptible, but the end product has a far better 'feeling' to it.
I'll bow to your superior expertise concerning perms; it's been a long time since I went to the hairdressers.
