I see you online.Please,do you know haw to solve problem with Midi Error.
I am test my Audya with Test program and test show some Midi error,allso I haw problems like Filipelou but I prefer your instruction and solve that.

Please if you know enything about Midi Errors.

No dusan even loading the sam file before i get an error on KetA02 and the checksum is 86AC4217

What is the 2011 update?? version 4.2B? How to check that update?

Filipe
That checksum is wrong.That is oly what i know about.Sorry cos I cant help you much.
About 2011 update Tone mean the last OS update vida USB sick when you can fined last OS 4.2b and you haw allredy in your kayboard.
What I can see after solve Ket02 is styles load a litlle slower to ram.Dont know what is the reason but that is the last fact.
Maby is right to try reload checksum Ket02 again.You haw nothing to lose...
Good lack

I dont know if the sam file is loaded because nothing happens on the screen but if that checksum check i made solve the problem of internal audio files,for me is fine.

The 4.2B version of the site is the same on the pen right?
Well i have that version.

Filipe,
only indicator if SAM fail is lodet is a little noice when you push Enter button.That you can hear like when HD want to load something(know that is not good anaf explanation)

About wersions of OS must be the same all coppys,but maby somethig go wrong and in some coppy mis little part of file.
My coppy of OS is from Ketron official sita and belive is with no little errors.

I am fairly certain you must have a MIDI cable connected from MIDI in to MIDI out forming a loop back. Its standard practice on any keyboard or organ.
