Hey - Yes, I got to play the Pa588 at Summer NAMM. As George says, it is the Pa500 but with the same RH3 Graded Hammer Action, Stand and Half-damping Pedal that come with the SP-250.

The additional "PIANO" sound is from the C-720 - the Korg top-of-the-line home console. Four sample layers deep and with string resonance and hammer samples, etc.

Some guys just demand the 88 notes, and won't give it up to get the Pa Engine. So Korg made the Pa588 for them.

For some one like me who is a piano player first, it is nice that the Style Engine just keeps pace with me as if I was just playing piano alone. I dug it.

At the booth, Korg said the price will be about $2600 - a hundred dollars higher than what George Kaye guessed.
