Not correct! Korg has always marketed they arranger top models towards professional players. Here is an excerpt from the Pa800 brochure:

"The Korg Pa80 is the most successful Professional Arranger keyboard ever produced. Used by tens of thousands of musical professionals in every country of the world, the Pa80 is the industry standard. So, developing the next generation of Arranger from Korg - the Pa800 - required we understand the needs of the modern musical professional whilst respecting the technology chosen by so many musicians worldwide."
