is it possible...

...to map whenever I press some button on midifighter(for fx) at the same time current positions of the FX knobs in traktor are shown with leds at novation nocturn http://images.thomann.de/pics/prod/206095.jpg?

or the same thing with bcr2000 (still didnt decide which to buy)?

sure it's possible. map the knobs output to the led of the nocturn, if you now press the corresponding button on the MF, the leds should show you the position.

I have a nocturn that i use for production because its so handy that the automap controlls all my vst's.
When I tried it with traktor I hated using it because the mappings never saved properly and when they did sometimes they wouldnt reload properly.The other thing I didnt like was the feel of the encoders,even after I adjusted the sensitivity on traktor they still didnt feel right to me for eq's etc.

I picked mine up for €35 on adverts.ie so for that price I cant really complain!

In my country novation is 90 eur and BCR2000 is 130eur. After your post, bcr2000 now is the first option for me.
Ive already bought MPD24(it has midi in for bcr2000) but it hasnt truly 360 knobs, it send only absolute values.
Do you have any other controller in mind with faders and 360 knobs, with leds, and some buttons?
Just need some other controller beside VCI100 to use for 3rd deck and samplers.
