I am a Pa1X owner and lover of the board.
I sold my TyrosI to get it. I still have the PSR 3000 Yamaha, but I will probably sell it because I spend the majority of my time on the KORG.
However, I see something in the new Roland which I like, so I posted the demo here. The Korg really needs 128 notes of Polyphony.
Where did you hear that KORG was going to introduce new arrangers this year? I haven't heard that and no one is talking about it on the Korg Forum.
