Hi,
yes, the new TP6X Fatar production has this annoying problem.
These keyboards originally had a rigid steel base and were very solid. For some years now it has been replaced with an ABS base that tends to bend.
I solved it by building a 5 cm wooden strip on which I added a strip of felt. This strip has two feet so as to unload the weight onto the base of the organ frame.

Ja, das Problem ist wirklich nervig -- seit ich das zum ersten Mal bemerkt hatte, konnte ich es auch nicht mehr ignorieren. Und bei dem (Auf-)preis, der für die TP6x verlangt wird, überhaupt nicht okay.

Yes, the bar rests just after the steel support, in a position that I would define as just beyond the center of the keyboard.
In that photo I was calculating the distances and I used synthetic wool, then replaced with a compact strip of felt.
In addition, I added a strip of hard felt inside the keyboard, without altering the key dip, (between the keys and the ABS base, as Viscount does in its keyboards; to do this you need to remove all the keys) This allows a solid landing and without rebound of the key.
This work was done for all three keyboards, and I must say that I have completely solved the problem. Now it seems to play a real professional keyboard such as a pipe organ.

Bei dem Preis, den so eine Digitale kostet, ist es eine Schande, dass man selber handwerklich tätig werden muss um ein eigentlich selbstverständliches Ergebnis zu haben. Zumal das ja früher offensichtlich nie ein Problem war. Meine NOBILIS von 2021 neigt auch dazu ...

Zumal es eine bewusste Verschlechterung der Qualität zu sein scheint. Ich bin relativ sicher, dass Käufer einer TP65LW, die ohnehin schon viel Geld ausgeben, auch noch die (doch sicher nicht mehr als) 10...25 Euro Differenz an Produktionskosten pro Manual oben drauf legen würden.

I believe Fatar changed the design of these keyboards about 20 years ago.
Some Ahlborn models from the late 90s still had steel frames, later I only saw ABS frames.
And yes, Fatar's "Ivory feel" surface is terrible: it deteriorates after a few months.

These are the old version with the all metal frame.
Didn't have key velocity. But the construction was much more solid.
