Need help with TS12 76 weighted keys

[Italianesq1]

Hello
I have a ensoniq ts12 keyb.
The white keys make a strange crack noise
While the black ones doesn't. Is this normal?
Here is the video.

Thank you

Rick

Hi Rick and welcome to Keyboard Forums!

That definitely doesn't seem normal, have you got in touch with the manufacturer? Has it always done this or has it just started recently?

I asked to the previous owner who sold me the keyboard,
before sending it he told me it was completely checked and that
It was ok... I am waiting for his answer hoping that some TS12
user can give me some hints on this problem...
Thank you
