Keybed Velocity Problem

[drewtheshmoo]

Hi guys,

I think `velocity` is the term. But I've got a couple of keys (both C#s incidentally) where there's little room between the note sounding soft and sounding like the PA has just fallen on it. And it doesn't take much pressure on the key to make it go full volume.

Is this a problem that's easily fixed? Does it need to go back for repairs? It's well looked after and doesn't get knocked around so I don't understand why these notes are dying, but it makes it really difficult to play anything that involves C# in the upper octaves without it sounding plonky on those notes.

Thanks

I think you will need to replace some rubber contact strips - I've done it sucessfully with my Pa keyboard a couple of times.
You can get them from here:

Thanks for that. I've taken it apart and given it a little rub down to see if that works. If not, I'll buy some more contract strips like you suggest.

Do you know anywhere I could get the hammer for the krome 88? I've had a look on the same site you linked to, but they don't have the hammer for the krome.

Can't find anywhere in the UK that does parts so might have to ship them over from the US anyway.

Thanks again

I just want to add "me too". Perhaps a generic problem? In my case the lowest G# and (intermittently) D# one octave up from the middle. Neither have been particularly heavily used or hammered. (I'm not a hammering type of player.)

The first time this happened I got a real shock. It produces a nasty audio effect. I thought one of the loudspeakers had blown up.

The most heavily used keys in the middle are beginning to generate a rattling sound, I mean mechanically, not electronically audible.

I purchased a Korg Krome and within 6 months it has a severe double triggering problem where a couple of notes play as loud as can be played on the release of said notes. This becomes a very serious problem when playing a slow soft love song live when all of a sudden DONG! These notes will double trigger at highest volume 8 out of 10 times. Anyone with a solution please fill me in. As of right now I feel like throwing this thing out the window but I paid a lot of hard earned dollars for it so a fix would be awesome. Please help me anyone.

I've had this problem on older keyboards in the past, all Roland in fact. I've no idea if Korg keys use the same system so this may be no help at all, but...
It was quite an easy fix (if you're prepared to take the keyboard apart) by cleaning the contacts under the rubber strip with a cotton bud and alcohol.
Dirt, dust, abuse, and keyboards - don't mix.

My Bb key is doing this ... has anyone fixed this? .. did you clean the contact or replace it?
