How to "Fix" the rattling noise on your Numa X Piano ( maybe Nord too) and TP110 mechanism Show-off

I did reupload this video because I did insert a part that is the actual greasing of the key, It is from an old video of My SL73, but the process is EXACTLY the same.
As you noted I put Fix between quotes, that is because there is nothing to fix, there is nothing wrong with the keybed of your Numa's Fatar Keybed, the only thing to fix is your OCD, that needs to be put on check buddy.
That noise comes from the contact of plastic to plastic because the grease has been displaced towards the sides in the some of the non critical parts of the mechanism.
