hi all,
So im having issues with some keys. (posted in this forum) I have come to the conclusion ill have to open up and take a look to see what the issue is.
I haven't done any maintenance to this keyboard at all. I've had this for approximately 5 years now. I played another korg keyboard at my local music store, with what I'm thinking are the same keys as the kronos because it also had a "RH3 keybed from Japan" sticker like my kronos. all i have to say is wow! it feels so much better than mine.
So is normal to have to do maintenance of any sort on the keys? Or anything that would need replacing over time? I would like to tune it back up to like-new. I plan on keeping this kronos for another while.
thanks! _________________ Korg Wavestation EX. Nord Lead 2X anniversary. Kronos 2 88. Korg Minilogue. Microkorg XL. Roland MC-707

only you know how you play the keys, hard or less heavy, and how often you play your K
or whether you bought it used or new. Or gig with it.
I call those contributing factors.
Just the same, I wouldn't expect keys on my K88 to act funky after 5 years. _________________ Kronos 88. MODX8

you didn't explain the issues[ if you posted this separately, I missed it, sorry]. That detail might help narrow down what other folks would suggest.
No harm in removing the bottom cover and taking a look. Maybe there is some debris in the mechanism
I keep a dust cover on my keys when not in use. Based on my carefulness with my 8 yr old Kronos, the key bed does not need preventative maintenance at 5 yr mark, etc. _________________ Kronos 88. MODX8

As GregC just mentioned, it depends on the player's way of playing, if the unit is transported often to gigs, mostly placed on a steady surface or in shaky keyboard stands, how many hours of playing are on it, etc.
I practice several hours daily on my K2 with lots of advanced classical piano and after 3 years it still works just fine. As a comparison, a previous keyboard with a Fatar action was starting to give up after about one and a half years. I also did a few mods on my K2, so opened it quite a few times - all that to say I know the RH3-88 action is well-made and very solid.
Any digital piano or synth action will slowly wear out with years of use. Problems with uneven velocity are usually caused by dirty or tired rubber contacts. They are an easy fix and inexpensive if you ever need to replace them if cleaning them fails to fix the problem. For other symptoms like key noises, they often come from compressed/worn stop felts or rarely from worn hammer parts (for players with heavy touch). Those components don't cost much either but it's not for everyone to DIY as one needs precision and lots of patience to disassemble quite a few things. |

okay, this was kinda what i was getting at. I basically wasnt sure it i should clean up the contacts, etc. i wasnt sure if it would make a difference, but by the sounds of it, its possible it might help. obviously alot of factors are at play here. sorry for the poorly worded post aha. _________________ Korg Wavestation EX.
