hmmm. ytlevine: Can't speak for you, but as a still satisfied Tyros2 owner, I'm going to (try to) wait till the next gen Korg arr comes out first to compare it with Tyros4.

My feeling is that though each Tyros release improves on the last, the Tyros sound engine remains distinctly Yamaha Tyros, so keep thinking it might be nice for a diffferent (more Korg 'alive' vs 'cd produced') sound, especially if Korg comes up with something arranger kb revolutionary, like adding Karma features and/or M3 sounds, which would up the competition ante against T4. Though I'm able to settle with 61 notes, If Korg's able to include 76 keys in the case size of the PA800, that would be heaven to me! The problem now is whether I've got the patience to wait till the next Korg release (Feb/Mar 2011?) before upgrading. - Scott
