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.
