In principle you could remove the strip which shall simulate the "snap" point of tracker touch.
On the FATAR web site
http://fatar.com/Pages/Intro_production.htm you can check which modles have got the "snap" and which not.
However, be aware that the touch (i.e. the key weight) of their models beginning with "TP/60L" is still very soft when you compare it to pipe organs with mechanical action. What I mean is that the keys sink in with little weight and there is not much more needed to pass the "snap" point.
Contrary, the key weight for real tracker touch is much harder - see for example some diagrams at the site for Schwindler keyboards
http://www.fabiomancini.altervista.org/hauptwerk/tastieraENG.html.
My recommendation for a theatre organ:
If you plan to go with FATAR keyboards I would choose the TP/60LF model ("F" stands for the front shape of the keys).
I would not take out the strip for the "snap" effect as this assists a little your touch, i.e. it helps you to not only hear but also to feel when the key is halfway depressed an the sound is triggered via MIDI.
If you want to take out the strip (for a few keys as a test) you can do this. But note that the touch is extremely light and the keys may not quickly enough come up again. It might thuis be necessary to replace th 61 coil springs at the key ends by harder ones and also distinguish with their hardness between natural and sharp keys.
Of course, the keyboards of the original theatre organs with electro-pneumatic consoles did not possess a "snap", but since this is very soft with the above mentioned keyboards I do not consider this helpful rather than a disturbing addition.
