Subject:Fryin' the CX3- (DANGEROUS and UNSAFE V2 UPGRADE)


All CX-3 owners,

Last night, after reading about the upgrade
avaliability, I downloaded it and proceeded to the
upgrade. Unfortunately my CX3 got fried along(I almost
feel like crying), even though the utility said it was
upgraded successfully.
After the process was done, it doesn't power anymore.
That's it; it's death or at least in deep coma. A
fomer gorgeous instrument is now only useful to make a
fire pire $2000 worth!!
My conclusion, after much thinking and then rethinking
is that the program has a bug and it's not safe using.
I repeat, IT IS NOT SAFE!.
This doesn't mean necessarily that your CX will die
along the process. The program could either flawlessly
operate the upgrade, as it could kill the organ, in
spite of all cautinary measures. I strongly discourage
you from self-upgrading. I'd rather advice on having
it upgraded by an authorized Korg technician. If the
CX is fried, then it'll be their responsability and
you won't be on your own. If you still wanna do it
yourself, I recommend you to keep reading as I'll try
to prevent you against the unfortunate incidents that
led to mine's defunction.

Ok, so I proceed with the upgrade instructions.
Disabled screen savers and energy economizers. Set
CX3's global channel on 1 and reboot on transmission
mode.
Performed all tests successfully(steps 1-4), and then
crossed fingers and went for the non-protective fifth
step: that's where the actual transmission takes place
and it's the most critical stage. After a few minutes
of transmission, a dialog popped up. My heart just
bounced. It said a timeout error (7) had been
produced, and I was adviced to re-hit the "start"
button, as it would send data all over again.
If this persisted to fail, I should close and reboot
the program. It also informed me that I should NOT
power the CX off.
I did what the dialog said, but it never happened to
happen. Timeouts kept hapenning, all at different
progress times and places (I mean that it didn't get
stuck repeateadly on the same data). Sometimes
happened shortly after the upgrade started, sometimes
it would take a long while. After a good amount of
tries, it got thru. A dialog box said the upgrade was
successfully installed and the Korg's display read
"Received EOF". I click on the dialog box and says
"Enjoy new V2 firmware", and the program closed
itself. I turn the power off on the CX, power on again
but it didn't light up. It's dead, long gone.
As I said, after much thinking, I think I know where
the problem lies.
This is VERY important, as following the program
instructions CAN FRY YOUR UNIT as well. The program
ain't SAFE.
Whatever you do, should you ever have a timeout and
the dialog box appears to you saying to retry
transmission data hitting "start" button, DO NOT DO
IT. I repeat DO NOT DO IT.
I happened to observe that the data transmission
operates in two different stages: first the program
sends the instructions for the SUB processor and
immediately after sends those for the MAIN processor.
NOW, IF you happen to experience any timeout during
the SUB transmission, whenever you hit start it will
skip that transmission and go directly to the MAIN
transmission, leaving the chain uncomplete.
If you are as unluky as I am and the MAIN
transmission finishes, YOU WON'T BE ABLE TO RESEND
data and thus INSTRUCIONS WILL BE UNCOMPLETE.
I repeat, there's a BUG in the program and if a
timeout happens during SUB processor transmission and
hit start again, IT WILL SKIP that transmission and
transmit directly MAIN processor instructions only,
LEAVING THE SEQUENCE UNCOMPLETE.
I guess that in case it happened during MAIN
transmission, it would be safe to hit start again, but
I cannot assure you anything.
All I'm saying is not to go the way I did. Instead,
and should you experience the same problem I'd restart
the application as needed.
I understand that by perfoming the upgrade I was
taking chances. I used a regular midiman joystick port
midi connecter. I guess this wouln't fit Korg's
definition of a pro midi system, even though it always
worked well and passed all tests.
However, now it's too late for me to try with a better
configuration.
I have no clue how much is gonna cost me, and to be
honest, I don't even wanna think about it for now.
Only shipping costs are going to be a hig tad,
without a doubt. Plus a new main board (Jerry, do you
have a figure perhaps?). Ouchy!!!. This is gonna hurt
for sure. It hurts already.
SO beware. Now, I'm out for some real hardcore
whinning. Thanks god I still have an electro to gig
with.
