I have a K2-88 that is about 6 months old. Yesterday at a gig A1 made a clicking sound, has some resistance and does not return to full release position. You can feel a definite mechanical resistance when depressing this key. Oddly, this is probably the least played key on the keyboard. I only use it to trigger a few phrases in a few sequences. Does anyone have any idea if what this might be?

Perhaps it's the same thing on original Kronos : Keybed is going to the front of the unit and make noises. Put your unit upside down, loose the screws that holds the keybed through the wooden board, they are slightly tiner than those all around the metallic shell. Put your unit on the back (the side with connections) and tighten the screws, that should do the trick =)

I agree with the excellent suggestion that Niarf made.

Do check that there's a gap between the keys and the front bar.
(Also any obvious front bar damage in that area).
The gap can be adjusted by slackening the larger headed screws underneath,then either use the cardboard spacers that came with the Kronos,or anything else suitable,by placing them between the keys/front bar and re-tighten the screws.

As a side note....the gap can be set by eye judgement as long as it doesn't go too wide and the keyframe is prevented from moving during screw tightening etc.

The smaller headed screws will not provide any adjustment.....they hold the board to the frame and have pre-set positions.

Try this first,then report back etc.

Best Wishes.

If possible, I'd let KORG repair it since it's only 6 months old. Yes, you can probably do it as suggested, but just my 2 cents, do it under warranty repair in case you have a problem in the future. The it's documented. That's what warranties are for.

Good luck and sorry you're having a problem.

Can't argue against the warranty repair route and is worth considering.
However,a quick check could help eliminate the suggested cause,the presence of a gap and if the screws are fully tightened etc.
Further than this would be a matter of choice,but dependant upon comfortable capabillites of an owner,it may be easier for some,but not for others to attempt.

Many gigging musos do these checks/adjustments as a routine due to the physical movement of the instrument…..a static/studio one would have less of a need to do so,though.

It may be that the problem is elsewhere,of course,which would definitely mean a warranty repair.

I also wish JPROBERTLA good luck with finding a solution.

Am I right in thinking the the RH3 keybed is still suffering issues ?

I am currently on the edge of buying either the K73 or K88 and this all makes me jittery about spending close on three grand in the case of the K88 for a pro league keyboard to then start having mechanical keybed failures like are being reported.

I was under the impression that these problems had been addressed back in 2003 and as these RH3 keybeds are made by Korg themselves how can the latest K series have issues still ????

At three grand no expense or design should be spared and Korg users should not be in the position of Beta a Testers for this. Sorry if this sounds harsh as I believe the Kronos to be very desirable for a lot of reasons and some will say these are small percentage problems, but it still has rumblings from the period previously and if I was unlucky enough to wind up with a malfunctioning Kronos with key issues I would be seriously P off.

Maybe I will sit on the fence a while and see what gives

If you mean the double strike problem,I believe that has been cured for newer models.
Older ones may present something similar over time,but replacing the key contact rubbers usually remedies that.

This topic concerns the movement of the keyframe and is not regarded as a major problem in itself.

So,yes....go ahead and treat yourself.....then enjoy the whole experience of the Kronos !!!

Best Wishes.

I don't ever recall a Pro Keyboard that had to have the Keyframe tightend by the user especially for a instrument that will get road use albeit it fully flightcased. Would not using a lock nut adhesive on the screws or bolts that hold and position the Keyframe prevent these fasteners from working loose?

Just seems a half arsed solution that Korg manufacture a three Grand instrument which will inevitably be moved and then have to either rely on a service centre to put it right or rely on DIY remedial work from the users.

I have to admit that while I am at the threshold of saying hell just get it and see the thought of loosing it for repair work for weeks on end could just end up outweighing what a competent keyboard this is.

Decisions, Decisions !!!!

There are many of us that share your sentiment and opinion regarding the saga....myself included.
However,setting the misgivings aside and playing the instrument tends to melt away such things.
Believe me...I've had some problems with my Kronos,but soon became lesser of importance when getting into music making.

The usual turnaround at Korg Uk is within a week,for parts that are in stock.
The longest wait in my case was two weeks overall.
So,here in the Uk,it's not too bad.

Hopefully you won't ever need to have a repair !!

There....I've helped you make the "right" decision ....then

I did send my Kronos to warranty for that, three times, now I do it myself, they can't verify =)

Niarf is that a Kronos 2 you have ?

Thanks Pedro, I have not had much faith in Korg UK after they accepted my brand new Triton Pro back after seven days of buying it where it sat in their service department for three weeks !

I need to carefully consider how I will spend my money

I don't believe you should over react to 1 or 2 users experience. At least, I do not. And it would seem logical that the screws attaching the keybed just happened to be a touch loose.

Tomorrow, you will likely read something else that makes you pause. The next 4 days you will read how great this board is. And its a fabulous keyboard for the $.

all the 1st and 2nd gen Kronos 88 came with 4 or 5 inserts ( cardboard?) that made the keybed inert when transporting/shipping.

while many likely discarded those inserts, it would seem cautious to keep them and reinsert them when moving this heavy board. its a 10 second step.

I understand what you are saying Greg but I have in all my years of using keyboards as well as selling them needed to have cardboard inserts to hand to block the board whilst in transit and have never heard of such a practice on any other keyboard.

Korg, Yamaha and Roland have always had high quality keyboards IMHO and one would expect that in 2015 Korg would have continued this process.

I always have my keyboards in Full Flightcases and move my boards myself with kid gloves and that is the method I would use with a Kronos should I get one. What would be a stopper for me is that if I done all that and then found issues with the keybed I would kick myself.

I hope to spend some time with a kronos later next month and hopefully that will allow me to fully test the New RH3 action and build quality of the Kronos 73 and 88, I think only then that I would make a choice

How long ago was that ?

My experience was last year,over a period of several months in total.......I have mixed feelings regarding Korg UK.
Some of their work and responses were excellent,but unfortunately their diagnostic skills let them down in my case.
(Can't find the problem...so we can't fix it....).

Initially my keyboard was sent via the dealer,a two week turnaround,but when I sent it direct.....Monday collection,it was returned on the Friday.
The state of the original carton was in a really bad condition,holes everywhere.....but the Kronos remained in good state.
Had difficulty in moving it from an upstairs bedroom (my "studio"...) was a task in itself on my own,the K73 is do darned heavy.

Anyway,overall,despite an unresolved problem,I can't really complain about Korg UK.

If you're wondering what my problem was (still is...).....it's the velocity variation on some keys using the German Pianos.

The end opinion from Korg UK,including their main demonstrator,was that it's a characteristic of the German Piano and they are all the same......
They did invite me to their workshop,together with my gear,to investigate further,but I had to decline their offer...due to health reasons.
So,I accepted their final conclusion that there wasn't anything else that could be done.

I've got around it by using the Japanese Pianos instead,with my own settings etc....which play correctly and am happy with the results.
Every other voice plays fine as well.

Those who have not had any problems with their instruments obviously can't really appreciate the impact it can have on an owner,but in my opinion it shouldn't really put
anyone off buying a Kronos.
Being such a wonderful instrument can offset such things,eventually....as said,playing it soon overcomes the negative side.

Forgive the longevity of my post.

Hope your decision will be the right one for you.

Best Wishes.
