Strange.
My Kronos 88 did not have the cardboard spacers when I pulled the unit out of the box.
All of my white keys are sitting right at the front of the bevel. Near the back of the keys, there is a good strip of felt showing.
Is this normal?
How do I get the cardboard spacers?
They were never in the box.
Here are two pics of my 88:

Sorry, I don't know why yours doesn't have the spacers. But, as long as your key action is good, you're good to go!

whoa, that 2nd photo is a surprise. I can't believe the keys are level with the bevel ( ? ) or front metal strip.

Your 88 keys should be 1" higher or above the front metal strip

Hey all... I have a sticky G below middle C, and I slipped a paper in front between the keys and ran it down the length of the keybed top to low and in reverse. Both times the paper stuck at that dreaded G.

I'd love to try the spacer fix by I didn't have any with my Kronos 88. Any recommendations?

Also I'm trying to be super sure on the procedure. I don't see two bolts that stick out more unless you count the rubber feet. The nearest I can see are three screws towards the front ahead of some smaller ones. I think the OP had a 76 so maybe that's the difference?

Thanks in advance

I don't think there is a difference. Loosen the large bolts on the bottom, scoot the keybed backward just a smidge, and then retighten. There's nothing magical about the spacer: It's just thick paper (or skinny cardboard). You could use a couple pieces of construction paper for example.

Good luck,
Mark

I have this same problem after getting my K back from repair, and I tried loosening all the bottom large bolts, but my keybed was still rock solid and didn't move when I tried sliding (pushing pretty hard) the spacers in.
Should I have the K upside down, or right side up on a stand when I do this? I did it the right side up on my stand - I didn't dare unscrew anything when it is upside down - and I also didn't dare removing the bolts - just unscrew them a good bit but they're still in.
Thanks,
C

I was able to do it right side up.

Hope that helps,

I have to claim dumb user error on this one.
I had only loosened the large-head-screws on the bottom along the center line and not the ones towards the front. Once I also loosened the screws on the bottom front side the keybed slid back leaving enough room for the keys to go up and down without touching the front bar. This forum is such a great resource!

Thanks all,
C

I am SO HAPPY TO FIND THIS, people at guitar center and other musicians thought I was going crazy.

MAke no mistake, this problem with the keys clicking happens with Kronos X also, and I went thru 4 korg kronos. A guy at guitar center said he does not even wat to sell me anyhting because I was annoying. I will work on mine and let you guys know the results.

By the way Korg also thougt I was making it up.... I'm happy to find a group of people that understand these annoying isssues.

Thank you

Hi Sharp,

Can we make this thread sticky? (Pun not intended) It seems to be helping people.

Thanks,
Mark

I just want to say that I have a Kronos X 73 only two weeks old which developed a sticky B on the lowest octave with associated clunking noise.

I was going to send it back but I tried this fix and it totally worked. The keyboard is smooth as ever now. Thank you so much.

You're welcome.

Sharp, what would you think about making this sticky?

Thanks,
Mark

Thanks for the help in this thread maphill.
Do I have to loose every screw with large head underneath the kronos or is it enough with the ones in front raw, nearest the keyboard?

Before I try to unscrew the keyboard I tried to insert a piece of paper between the sticky key and the frontpanel, and then take the paper out again, and that helped to get rid of the sticky key problem. Very Happy
So now its only the clonky sound on release that is the problem. And to fix that I guess I have to loosen the screws.

Now i found out, by another thread on this forum, that the problem I have that make the keys touch the ftontpanel and make a sound, is because Kronos doesent have any support on the middle rubberfeats, only at the edges.

Thanks a lot! +1. Solved my problem too. (Started after the extra hard drive was installed. Unfortunately the musicshop was bankrupted, so couldn't return to them)
