Help! Fix for Fatar Keyboard Squeaks (Kurzweil PC88, Ensoniq, Korg)

Help! Fix for Fatar Keyboard Squeaks?

What is the fix for a Fatar weighted keyboard that squeaks?

See below.

Note: on many keyboards - getting to the keyboard assembly is an hours work at least. SO..... if your tech does it figure on 4 hours of work - in my opinion.

Or..... do it yourself like I did!

OK. I sourced out the problem.

Which is NOT really available on the web. SO here is it.

For all those who have squeaky Kurzweil PC88's or Ensoniq weighted keyboards, this IS the reason why they squeak.

It's the worn out felt on the hammers. The solution is ONE of 3 things:

1) HARDEST Replacing the felt (hardest but cheapest longest solution) IF you can find the right felt
2) MEDIUM Getting new hammers which means the felt is new
3) EASIEST Easiest solution: putting a slight amount of grease on the felts

Thanks for the information!
It will be a big help to those who need Fatar repairs.

Been there and done that with an Ensoniq KS-32, TS-12 and a Fatar StudioLogic 1100.

You can add, cracked hammer weights, broken key stops and assorted other repairs to my list.

That is why I will never, ever, ever again purchase any keyboard that has a Fatar action.
The plastic they use is far too brittle and it ends up cracking.

It's the plastic equivalent of "pig metal".

And for anyone considering purchasing a Fatar based keyboard used, make certain to pick it up and put it on end.
Listen for plastic parts rattling around inside.


BTW you can get the felt at a craft shop.
If it's a little too thick, you can press it down under some heavy books.
I found the perfect stuff though.

Peace!

The felt strips are 1/20th of an inch thick and 1 5/8ths inch long, 5/16th wide.

One for every hammer - so for me 76 hammers X 1 5/8th of self adhesive felt strip. Thats 123.5 inches or 10.3 feet of 1/20th inch thick felt strip.

If you have an 88 note keyboard you need 143 inches or 11.9 feet of 1/20th inch thick felt strip.

The felt strip that goes under the keys is 1/8 inch thick and 1/4 inch in width.

For the 76 note version you will need 2 - 42 inch strips (total 84 inches of 1/8 inch thick & 1/4 width felt)

For the 88 note version you will need 2 - 48.5 inch strips (total of 97 inches of 1/8 inch thick & 1/4 width felt)

Yep...
It's an arduous task at best.

BTW you don't have to replace all of them, although as long as you are inside the unit it makes sense.

Never again.

BTW, looking at your picture felts.jpg1, you can clearly see how poorly the hammers are manufactured.

See how some of them have the weights showing through the plastic and others have the weights completely encased in plastic?

The ones with the weights showing through are the weak ones.
They will crack and fail because they are weak.
It's usually along the sides that they crack.

It's piss poor manufacturing IMHO.

My studio has a Roland 700 as a controller and I use a Roland RD-150 as my gigging weighted keyboard.
I hate unweighted units.

The RD-150 gets a lot of abuse and has never in all the years I have owned it so much as made a clunk.

I had to have the entire Ensoniq KS-32 Fatar action replaced 3 months after I bought it, under warranty.
The replacement wasn't much better.

Great!!
Thanks!

I still have the KS-32, but it's just a sound module now that gets triggered from my Roland.

I unloaded the TS12 and Fatar 1100.

On a side note, I always enjoyed Ensoniq synths.
At least they had character to them unlike some of the others at the time.

Hi. I have an Ensoniq KS-32 that needs the felt replaced on a number of the hammers. It has squeaking and clanking. I have been searching on the web for 1/20" or 0.050 or 1.27 mm felt, but have found almost nothing. There is plenty of 1/16" felt to be had, but I want to do it right. Lots of work to replace them all. Can anyone help me to find a source either on the web, or in the USA. Thanks. Bob

Great thread! I wish there was more about this as new products come out with fatars and they probably all need some service one day. I have 2 squeaky keys on my Sl mk2 and searching for the silicone based grease. As i read it is quite hard to apply?

I have an Ensoniq ASR88 with squeaky keys. Really not looking forward to diving into this one. Are modern 88 key controllers better designed than the Fatar?

I'm at the place where it's almost easier to just buy a Kontrol88 or something, rather than apply grease to 88 keys in this beast.

Anyone else have experience with this?
