Tony,
When I go into my store this morning, I will spend time with playing sounds and report back to you.
The 16 real voices are all brand new sounds with special attention given to a very realistic sound. Using effects and aftertouch and dynamics to make these sounds sound more realistic.
After playing the 16, I found myself looking for more pages with another set of 16, but it looks like there are only 16 preset real voices.
More later!
