Hi Deanne,
no really, it's actually based on the PA3X without all the bells & whistles.

http://www.sonicstate.com/news/2012/09/05/-new-korg-arranger-keyboards/

PA500 was based on the PA800/PA2x.

KMA really is sort of unique.

Unlike Yamaha , Korg appear to bring out the Top of Line arranger first, then the mid level arranger a year or so later, wheras Yammie put NEW features into the mid level PSR's first, then bring out the top of the Line arranger.

On a very quick look it doesn't seem to be much different than my KMA except
for key size and the songbook.
