Led toggle on NanoKontrol Studio with Reaper

[tit-france]

Hello, all, sorry for my english ( french class )

I buyed a NK Studio fotr use with reaper. My NK 2 workde fine, but with the studio, on cubase setting, all is right except ... the sliders ( always moves 2 by 2 like if tracks are multi selected.

So i decided to "relearn".

the project start slowly to works except for the led, who are on "momentary" . exemple, i click on "mute", the led is blinking but doesnt stay lighted when mute is activated.

I try to put in "external led" in Korg Kontrol Editor, but doesnt work anymore. ( output seems to be activated in Reaper midi preferences).

Somebody know how to resolve this aenigma ?

Merci d'avance
