Let me start by saying that ketron make the best arranger keyboards in the world and i have been buying them for the past 20 years or so. but they have the worse customer service on the planet, i have called them, emailed them and sent messages via the website many many times but never get a reply. my problem is , i have an audya 76 that i bought used and there are errors on the hardware, firmware ketao2 d7dt01f6 these are the error messages i get when i do a hardware test. I just cant believe that on an AUDYA there is no way to do a restore to factory setting, (i have done the f10 and unplugged)many times no joy.
If anybody knows how i can get this keyboard back to factory settings please let me know. thank you in addvance.

Good one!
Hoping they weren't using google translate, here's my understanding:

- Hook the Audya with the PC.
- Look for the AUDYA:\SYSTEM\INIT folder browsing from the PC
- Make a backup (just in case) onto your PC
- Delete the content of the folder AUDYA:\SYSTEM\INIT
- Safely remove USB connection
- Restart Audya.( turn off and then on again)

Most likely, the files and styles are ok in there. It is the way that the O.S. sees them... Just like the indexing function in Windows, sometimes it can go wrong and the function does not display correctly the content of the HDD.
That's the reason of deleting the incorrect INIT file... This is my guess. After deleting, most probably, at the next reboot, the O.S. will create another INIT file, and will fix the problem. Give it a try - you cannot go wrong.
Good luck!

That is correct danielbordeiu
