Roland KR 3000 second hand - key problem

[musicspirit]

Greetings, I have the opportunity to acquire a second hand Roland KR 3000 .. the only problem is a couple of the keys volume sensitivity is stuck on maximum volume and when you play the keyboard they really pop out LOUD making the keyboard pretty impossible to play as you can imagine...

I have seen spare replacement keys on eBay.. my question is:

1) if I bought the keys individually could I replace these myself or is it a specialist job for a technician?

2) Is there perhaps another procedure that would cure the problem without buying new individual keys? ie the keyboard was left in a dusty place and that might be why the contacts are damaged

Any helpful answers appreciated!

best

When a keyboard is sounding max velocity on a couple of keys the problem is dust and crud under the contacts of those keys.

Buying new keys won't help.

The solution is cleaning or replacing the contact strip under the keys in question.

Usually all that's required is opening it up and removing the contact strip and cleaning it carefully with denatured isopropyl alcohol and then replacing it as you found it.

It's not too big a job for a DIY person but be very careful to mark all connectors and screws and put them back exactly as you found them.

It helps to take a few photos as you dismantle to use as a reference guide.

Here's a few videos on how it's done in general.
