rmx2 mapped to ableton

hi folks

i.m trying to map rmx2 to ableton live 9 , the buttons work well , but i got issues with the faders,that is, its impossible to get a precise control with the faders, they send a illogical and not stable numbers sequence, how can i get control over this number flux and have a precise mapping on live9? 
i thought about using the midi mapper , but it does not recognize the rmx2...
thanks for cooperation 

Hello dubast,

You are probably lost with the MIDI 14-bit resolution.
Please make sure you set MIDI learning in Ableton in 14-bit as described here
