So I guess the Pa1X PRO can NOT do what you want??? JJ has not bothered to answer your post and he is one of only about 2 people on the planet that own the Pa1X PRO at the present. He would be the one to know whether it can or can't. I guess all the information on the Korg PA site about the Pa1X PRO doesn't mention it huh?

JJ, where are you when we need you? The gentleman has a question about the Pa1X PRO for you... ^.

The Pa1X PRO would be a new contender to supplement the SD1 if it does what you want it to do. I think you may find the Yamaha PSR 9000 PRO a worthy contender too. You want 76 Keys, right? Both the Pa1X PRO and PSR 9000 PRO have 76 Keys. The Tyros has 61 Keys.

Best regards,
Mike
