Just curious on why you gave up on it? Too much board for your needs, etc?
Zuki I had two Pa4x units, ......best arranger kb I have ever played..
it's ALL PRO for gigging...

Needs did change, I reassessed my priorities, and restructured my rig for what I am doing now. That's not to say down the road I won't have to do it again.;) But for now I am happy. I would recommend the KORG Pa4x to anybody who is serious about their music,....they really addressed the NEEDS of the Pro player this time. Good luck to you.
