And this is exactly why they've put all their resources on developing more Real Tracks. The players are putting those nuances in because they're real players, not a GM soundset.
Something else to consider is how serious does a person take this as their hobby? If you compare this to anything else people do for recreation that costs a substantial sum and it's really very inexpensive. Compare the $1,000 minimum cost to skiing, both water and snow, golfing, model airplanes, whatever. People spend thousands per year at least on those things. Under a thousand for some software or Biab plus the Ketron SD2 is nothing. If you're serious, step up and open your wallet. Five grand is really more like it. You want articulation and control over samples? Go on YouTube and heck out a Tyros 3 keyboard by Yamaha or the new Korg Pa2X. This stuff is out and available already, it just takes some bucks but at the same level as other major hobbies.
