John, yes, I know sounds and styles are identical. That was what I mean with "similar sounds and styles".

About key size, it is possible I overemphasize it. But I can't understand the logic to put these different keys in PA50. It is the first time Korg put these "smaller PSR keys" in an arranger.
At the end, I can't understand really the Korg logic to make a new kb, the PA50, when it is absolutally similar in sounds, styles, buottons, functions, to PA60.

By the rest, I think PA50 is a great kb for its price, of course. But I would like it more if its keys were more standard size.
