Snareroll in Aphex Twin - 4

Just like everyone, I really like the RDJ LP and just love how those snare rolls sound on tracks like 4. Now it’s quit obvious that most of those idmy tracks must have been made with a tracker, also considering AFX posting that ProTracker Video, but I keep wondering why those snare rolls sound so smooth and pleasing, do you think it’s because they’re actually triggered on a Hardware Sampler?
