Serge, Congratulations on getting the Korg Pa900.
Having just upgraded to Tyros 5 from Tyros 4,
I can't afford to buy a PA3X too, so I'm now considering a Pa900 instead of the PA3X.
Does the Pa900 utilize the same 'Grand Piano Sample' & the same 'TC Helicon Voice Processor' as included on the PA3X?
Does the Pa900 include a Chord Sequencer? Is there a Pa3X/Pa900 feature comparison chart available anywhere?
In the meantime, just checked FedEx Tracking and it says my Tyros 5 will be delivered to me on 12/24. Just in time for Christmas.

Happy holidays & the best in 2014 to all at Synthzone.

Scott
