No I have not ordered the PA4X. I am done being beta tester. If I get one it will be after the first of the year.
And the SD7 is sold as well. I had it five months and was not able to use it reliably on the job. I feel it is now at last ready to sell to the public, but I lost patience.
I will play either the PA3X or Yamaha PSR S-970 for now. I am pleasantly surprised by the Yamaha. It works as it is supposed to when I turn it on, and it sure is easy to carry around.
