I just updated my PA4X. It was relatively painless but it took a while.
So far I am very pleased with it. The factory default sound, levels, e.q. are improved. The mic sounds great without changing anything!
I have not yet loaded my Songbook and User styles back. First I want to explore what they have done. I've already noticed that some of the styles are improved and the Keysets (OTS for Yammys) are improved on some.
Not sure how many new styles are there, but I'm pretty sure I've discovered a few I will use.
I have not loaded the free set from Korg that they just released.
I may have to skip golf and/or fishing today just to play with it!
Susan is making Gumbo anyway, so maybe I'll hang out, eat Gumbo and take a dip in the pool! Life is good.
