Hi everybody finally I found it! :) I can use first fader as mod wheel, second fader as vibrato, third fader as expression etc. I want to help you. It was really simple. You dont need to assign faders, knobs or use different xml etc. :)
First we need to donwload Korg editor to select our cc numbers which we want.
After it, start nano kontrol in CC mode. Press cycle and set while plugging it into the computer.
Than open Studio One, open "Configure External Devices" if your nanokontrol is added remove it. Add as "new keyboard". If you want you can write manufacturer device name etc. Its not necessary. When you added as "new keyboard" choose Receive from "NanoKONTROL2 1 SLIDER/KNOB" and Send to "nanoKONTROL2 1 CTRL"
Than open new project. Choose one instrument what you want. Enlarge track channel and dont choose your main keyboard choose "All Inputs"
And use your nanokontrol as a CC controller :)
If you want to change you CC number of your faders, close Studio One, open Korg Kontrol Editor. Click top Left button and choose Control mode from "Cubase" to "CC". Than change CC numbers as you like. CC1 is Mod Wheel, CC21 is Vibrato, CC11 is Expression etc. After you choosing what you want, in Kontrol Editor click "communication" and "write scene data" and accept it. Close Kontrol Editor its not necesseary to save it because you saved with "write scene data". Open Studio One and dont forget, sometimes in track channel "All inputs" changes to your main keyboard you have to check it. Enjoy! :)
