Tony,
As I have stated before, and I will mention again, I work with and for Ketron on various projects as an Engineer and one heavily involved with the GUI, design and code of our products, so from a design prospective this is information I ought to know ... so yes, this is an official procedure (which you may verify by contacting us at ketron@ketron.it if you wish to get more info on).
I have not made this available because this is the first time I am seeing a customer of ours complain of a 'Checksum' error! It's best to provide detailed 'engineering' information only when needed - else you may end up with a lot of people 'experimenting' with thier products and then getting back to us for solutions to problems that could have been initially avoided all together. I believe however, that we have provided our distributors with this information to use when/if needed.
Mind you, this procedure mentioned above is NOT for 'Init Phase error' correction (which is related to the Hard Drive or Sound board) but for the Checksum error the customer above was requesting assistance with.
I don't know why 'his' flash went bizar but there are a couple of environmental factors that could make a flash memory 'forget' it's contents and he could have encountered one of such ... I don't know for a fact and won't speculate either.
The file - 'Audb0000.pcm' is infact for KetA02.
Hope this answers your questions/concerns, and let me know if I can help you with any others.
Thanks,
AJ

Leezone,
I am easy to please, I don't like been drip fed information, if there are problems and people know the answers and people are struggling with kit, there needs to be full discovery and disclosure. Why is flash memory falling over, I have never heard of anything that is so unstable, it's like Miscrosoft 3.00, why are so many people frightened of turning on their Audyas, will it work won't work and if it doesn't who shall I turn to. Leezone, don't quote me look at the people with problems, it might be you next week and me the week after.
And this is more confusing there is no logic to this "The file - 'Audb0000.pcm' is infact for KetA02.
AJ is it possible for you type out the full list, which pcm is for which chip just in case our KB goes Hyper!
AJ what could these be "I don't know why 'his' flash went bizar but there are a couple of environmental factors that could make a flash memory 'forget' it's contents and he could have encountered one of such ... I don't know for a fact and won't speculate either.
Are the Audya electronics sturdy enough for World Wide power supplies, is there a pattern for these probelms???
Regards
Tony

TWD,
As you know I am not stupid, well nearly not, I don't have a tweek out of my Audya, there were problems in the early days but that is now all behind us. But there are still people with the same age old problems, INT PHASE ERROR, left and right side sound not working and people running CSUM with miss correct match. There must also be other people who are not on SZ who have the same problems, I can't believe they are only SZ users. TWD all I am saying is this, if there are quick fixes like a car known often occurring problems that the Ketron and AJ appear to know about that can help someone why is it not common knowledge. You know of all people TWD, in this day and age no one and I mean no should be able to damage a PC throught the keyboard (save for format drive "C") and likewise no one should be able to damage their musical KB loading or unloading software, they should be bomb proof, I have a Tyros 4 and I know of nothing that Yamaha would not tell you not to do. An update for a fix would be on the Web as and when you need it. I see the problem with Ketron is you are allowed to wander anywhere into the system files and this is where people go into stupid mode. With damaged flash there should be a simple routine, a press of a button 3 times with some warning to reload the flash, I am not even certain if you need any warning loading flash back on should be childs play. BTW is the process AJ is suggesting to this chap correct to reload one chip and is this what he should be doing, the KB has just come back from the dealer.
Regards
Tony
