it is the nx chip with less wave rom and less polyphony and without the excellent amp and speakers of the 7k. Less sounds, less styles, less panel banks, no custom, no wide colour screen, no EW expansion. Historically there has always been a midrange model launch in between the top model launches, only skipped by the 6500.

I know it is excellent value at it's price point because I've heard it, particularly since the CB7 is included too in the UK package, and will give the psr2100 a very good run for it's money, but at the end of the day if you play them, neither of them are a 7k.

so cheer up
