Repair of some keys: Roland sk-500


I'm trying to fix 7 keys on a Roland sk-500.
Some mute, some sounds too loud, etc..

I've never done this before so I don't know what this goo is
and couldn't find any answers

Under keys of Roland sk-500 - Album on Imgur

Do i have to remove it for the repair and what is it called?

Maybe there is tutorials /already a thread someone could recommend for this issue to read or watch.
Any advice is much appreciated


EDIT: I found now that i might just need to change the rubber contact underneath
But the goo, I still don't know about that

I'm not familiar with that keyboard, but I have had a few Rolands (the last one being a D50) and it used to get dirt in the pads under the keyboard. That would cause dropouts or notes to sound at full velocity. I would just take the keyboard apart then clean off the contacts on the pads. It's a pain but it works.

Those grey rubber things are the culprit. Just make sure you get them seated properly after you clean them.

It's hard to know from a picture, but I would guess the goo is just (lithium?) grease. If so, there's nothing to worry about with it unless it's dirty or out of position. Cleaning it off would probably cause worse action and/or stickiness or squeakiness.

For what it's worth, on one of my keyboards that got squeaky on a few keys, I've had acceptably good luck with a bit of vaseline strategically applied.

I guess I can take away some of it? another person told me it was an unnecessary amount of it I could use vaseline if I accidently take away too much?

Can anyone link me a site that sells plastic synth bags?
