Korg CX3 v2 double-triggering issue

(apologies for the exact same post on another forum, just trying for as much info as possible)

Well, I received my new (used) cx-3 today from Guitar Center...and despite me specifically asking the guy about whether the keys had lips on them--and him saying "no"--it's an older one with the lips. Serial number is less than 600, wish I'd thought to ask that instead.

And sure enough it double-triggers, and it's worse than I imagined.

I've seen other posts concerning this, and some suggestion of fixes and workarounds, but I've also seen info that suggests it can't be fixed (or the fix stated was "replace keyboard")

Now on the good side I have 30 days to return it to my local GC. I don't really want to do this if I can get around the double-triggering; the board is in fantastic shape and came with a nice anvil case and was a good deal. It sounds really good to me and it feels nice to play (the small lips on the keys don't seem to get in the way, though I only played it for a few minutes before having to get back to work...). Not to mention I just returned a pc361 two weeks ago after UPS destroyed one of the corners...these issues are not my fault but it's no fun to be returning these boards.


The possible fixes I've seen:
- firmware update. I don't want to risk "bricking" the thing, though I could bring it back if that happened...as it is the thing is not really playable with the double-triggering bug. I'll talk with my local GC and see if they'd do it (with me not responsible)

- midi the thing to itself. Meaning turning local off. If the thru still works to allow the CX-3 to be a midi controller I could deal with this, especially if it's a set-and-forget thing. Obviously a hassle to have a midi cable connected all the time and it irks me to have to do it.

Any thoughts? If there's risk involved it's going back.

give me a buzz - I'm going to sell mine, maybe we can work out a reasonable deal and then you can send that one back to GC. I have a second gen unit in good shape and is a later build so doesn't have that issue.

You can PM me or call me at 408-391-5381. I am in San Jose, CA, so not sure if shipping would be a killer - but I should have a decent box to ship it in.
