Does anyone know how to use the softstep 2 with mobius?

I just bought myself the softstep 2 and have managed to get it working with ableton live 9, but I cant figure out how to use it with mobius yet.

I watched this video tutorial : https://www.youtube.com/watch?v=Kb879h2Cdz0

Unfortunately it's aimed at softstep 1 users and I cant follow it. Any help? Thanks!
