Fatar TMK 88 - Velocity problem

[fova]

In December 05 I bougth a new master keyboard Fatar Studiologic TMK 88. It has 88 semi weighted keys.
Yesterday I found that there is something strange with the instrument. During playing some keys play little louder than others and some others play little weaker even if I used the same power of keystroke. It looks like an electronic problem not a mechanical one because weaker one is for example "G" key from each octave, louder one is "E" key from each octave, etc.
It was extremely obvious during playing of scales (C, D, E, F....) where I used the same power of press for each key. All of them were OK and suddenly one was little weaker. During playing of composition it was not so obvious.

Is anybody here who had a similar problem? Is it a common problem of TMK 88? Is there any way how to repair it?

I can, of course, return it to seller since it is still in guarantee period but it will take some weeks before I will get a new piece so I would like to avoid such solution.

Thanks.

My first suggestion would be to restore the programmable settings to the factory presets. I'm not familiar with the TMK 88, but I have a Studio Logic 880 PRO LS (or whatever the number is) and occasionally it will act up. Since the Fatar keyboards have programmable velocity settings and aftertouch etc., I would follow the procedure for factory reset. It may return everything to normal. Mine plays great.

Could you tell me how this is restored on your keyboard? From this I can got any idea how to do it.

Thanks

other than your problem...how has it been treating you so far?

I saw they're for sale for just 149 at thomann here in europe.

I've a TMK-88 and it's fine for organs, strings etc but I want to throw it out the window for piano... it has a naturally low velocity curve and notes jump out and in unexpectedly all over the place. Just been reading the SL-880Pro has lots of options for changing velocity settings but I can't find any info on this for the TMK-88. If anyone can help me out on this it would make me happy.

I can change the velocity curves on my sound module to accommodate the TMK-88, but this isn't the main board I use, so it's painful to have to keep switching settings when using a different board.
