Thanks Mike for the link to Irish Acts. They are now the best independent resource for Korg Synthesizers and Arrangers.
I hope Frankie gets his AwarenessEngine website up and running soon. I know he put a lot of work into managing the Pa80 discussion group. He loves arranger keyboards.
By the way, the 62 note polyphony limit on the Pa1X series does not hamper your playing in real life. Besides, you can always play the leads on a second keyboard and access the arrangement tracks via MIDI from the Pa1X.
