today i tried to check sum test in my Audya and i get KetA05 error..what can i do for fix it?

Why did you do the check, do you have any problems with the KB


Tony

Yes.i have problem with balance of outputs..right output sound is low and left is brillant than right..i use seperate outputs but same; all rights are low then lefts.i opened rear of KB and checked all sockets and sliders.but nothing happened...i will try to reinstall OS or first sound upgrade usb stick..i will make a record from kb than put in the web..you will hear the problem..anyway, have a solution for checksum error?

necdetdoni,

If you have a Checksum error, perform the following to reload the FLASH in that particular chip (which for some reason has gone 'bizar').

* Turn on your AUDYA.
* When it boots, press DISK to display the HD contents.
* Create a TEMP folder where you will be copying files into (shown below).
* After creating the TEMP folder, Scroll down to the file "9708f1av00.sam and press ENTER to load it. This prepares AUDYA to load the relative FLASH file next.
* When done, to to the SYSTEM folder and press enter (aknoledge warning by pressing ENTER again).
* Select the FACTORY folder and press ENTER.
* Select the SOUND folder and press ENTER.
* Go to the file "Audb0600.PCM" and highlight. [This is the file associated with the KetA05 chip]. Press DISK MENU and press ENTER to select this file (blue dot next to it).
* Press COPY (F1) to copy this file.
* Go back to temp folder created above and press EXECUTE to paste this file in there.
* Get out of DISK mode.
* Go back into disk and go into the TEMP folder to highlight and press ENTER on this file "Audb0600.PCM" to load it.
* When done, restart AUDYA.

Thanks,

AJ

AJ,

This is the first time I have seen this procedure and there a lot of people who have had problems with volume problems and Int Phase error, is this an official procedure and if so why have Ketron not issued this. Also it appears complex for someone whose first language is not English, would it be possible to do a YouTube clip for it and then anyone could follow it. And why is this flash going bizar as you say??

Regards Tony

PS This sounds a bit odd, that file Audb0600.PCM is for Chip 05, only Ketron could come up with something like that, presume Audb0000.PCM is for chip 01, this is what you said below:

"Go to the file "Audb0600.PCM and highlight. [This is the file associated with the KetA05 chip]. Press DISK MENU and press ENTER to select this file (blue dot next to it)."

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

Very well said AJ

it's tough to make Tony happy.

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???

Tony

Don't forget Tony - on SZ you are stumbling across a tiny, tiny % of Audya owners - those that don't post here are too busy enjoying a fully fuctional instrument. Believe it or not SZ is not the center of the universe.

All the checksum test does is makes sure the sizes are correct, if the size (checksum) is wrong it is corrupt and will need reloading from the hard drive.

Its standard practice (in the UK anyway) to ask a customer to run the test if they have a suspected issue. As AJ says it is very rare for an error to occur, I have only seen it happen once in the UK.

The reason for not posting the information publically is because we do not want people poking around in the system folder without good cause..If its not broke...don't fix it.

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

I have some problem with check sum, too. The test shows me KetA02 check sum error. Than I have done the reparature procedure as AJ wrote. Check sum was OK, but - the Styles instaled from Pen Drive was corrupted (with the blue point). Than I have reinstalled my Pen Drive - OK, Styles and Sounds seemed to be all right, but the check sum KetA02 shows error. AJ, can you help me, please? Sorry for my bad English.

Wouldn't be nice to be able to just clear these flash faults at the push of a button, it should be possible, at least for this chap Ferry. It's not asking too much is it.

Looks like the same chip O2 as well, thats funny!!!

And why are these people in Europe having to ask AJ on SZ 3000 miles away, there should be a techincal note produced or a patch fix, I work with flash upgrades on kit ebery day without hard drives. A laptop, cable and software is all you need and the kit is flash updtaed in seconds. Why is this problem with CSUM errors happening???


Good luck with it Ferry

As i posted earlier my keyboard went to dealer to check the problems but in particular sound left/right voice problem ,i have played with two different keyboards and these have also the problem.

AJ,
I allso chek my Audya for some errors and found error on
F2 KET A02 86AC504E 88F51D48 Err.
My question is if I want to fix that error,can i prefer the same procedur like You sugest for CET A05?

Thank you

I only have a moment, but don't worry about the F2 KET A02 error, there is a discrepency in the test program itself that gives a fail... Ketron are aware of this problem. It does not affect the keyboard in any way, its simply the test program is incorrect.

Are you sure? What happens when you are on the stage and you Audya fail out - that´s a great shame. The keyboards reliability is very important for me and I wouldn´t risk some problems every evening. I hope it will come some solution.
Regards
Ferry

errrrrragggggh,

TWD this is just what I mean, little sippetts of info held by a numbers of people, perhaps a fact sheet would put peoples mind at rest, if I run CSUM test what will I get and my KB is OK. I don't gigg with my KB but some people the Audya is their working tool and if it falls over in front of 100s of people wooops.


I will run a test on my KB and be back shortly

Tony

Tone,
I agree with you,its not some big deall,but if errors in program test mean incorrects in test program,what then mean athers incorrections,what members haw?
My question is:haw to do ather tests in Test program?I mean DSP test who dont working at all.The same things its for Micro and Voicetron test.
Eny sugestions?

TWD is correct about the F2 KET A02 error, there is a discrepency in the test program itself that gives a fail...

I have tested my KB.

Well there you go, you learn something every day, the day you stop learning is the day you die.

End what is heppened?Haw Test passed?

Dusan,

My KB is OK even with an error on chip 02, what TWD is saying is it is a common fault with all KB.

Tony

Ok then Tony.We must live with that nececery errors.....but please tich me haw to do some ather test like test for DSP,Mic and Voicetron test...on my kayboard dosent work at all.Something I doing wrong?

There is not an error with the keyboard, the checksum is fine the problem is the test program needs 'calibrating'.

Dusan, hold down F1 when you turn on your keyboard to enter test mode followed by F5. Then use the F buttons to select the test you want to run.

TWD,

Sorry I didn't mean there was a problem with the hardware, what I didn't know it was compare flash problem, it's good for everyone to know this now, at least when they run the test and see the error they will know not to worry about it, it does need a fix I suppose since if there was a real error on that chip you would know if it was an real error or the calibration was wrong. TWD this must be a product of the last upgrade, because my CSUM test has been Ok until now.

Tone,
thank you for sugestion.If I pres F1 for panel test and F2 for DSPO (0708) they work and I can see result of that two test.But,if I pres F3,F4,F5,F&,and F7 kayboard swich to exsact test but after that nothing hapened.Scren after a will not show eny progres or result of particular test.
Dont know if is a right procedur or I must pres some ather butons to see eny progres or result.

Thank you

Dusan

Press ENTER to run all the test on the flash mem it will go through all the test unitl the last chip has been tested.

Tony

Why run the test? when the test result shows Error, it's really OK. Is it when the test shows OK, there is an error?
skude

Tony,
you prabably dont anderstant what I say in provious post. You start Audya hardware test with F1 hold button and after a will pres F5 to swich what are you want to test.With F1 button you can test panel lights ON and Off,with F2 button you can test DSP shecksum and with F3,F4,F5,F6,F7 you can test ather stuf like DSP1,DSP2,INPUT,USB,and MICRO.
If you chouce (for exsample F3 or F7) or eny ather button except F1 and F2 after I press Enter button nothing hapened.Kayboard dont show eny progres or result of test...
I only ascking if that normal or I am doing somethin wrong.
Thank you once again.

Dusan,

Yes mine is the same, the mic test and perhaps TWD will tell us about those.

Tony
