"Korg Arrangers are not a “take out of the box and play”; they take a good amount of programing to get them up and ready."

Amen! I am trying my very best to be patient until I get everything like I want it on the PA3X. I can take a Yamaha, Roland or Ketron right out of the box and play a job the same day.
I'm slowly getting there with the PA, and learning to appreciate it's capabilities.
