Next on schedule after this is the Tyros 3 format; so we will finally be up-to-date with all current keyboards within shortly hopefully .....
Guess the T3 comment says a lot.
Anyway, the latest update of SW XT is 4.03, and PA3X are in the menu. So are Audya, but only as a load option as far as I can see.
sorry to see your problems with Audya still not ended. Hopefully you believe in Santa Claus, if no solutions this year ..... maybe next bring up something to fix it.
Guess you know the Ketron way: T T T
