Xpantastic!

Hello I'm new to the xpander (and synthesizers in general) and was wondering if someone could help with a little advice.

I have an evolution mks-149 that has lots of assignable knobs that i would like to map to various parameters in the xpander (i really dont like the encoders on the xpander, they take so many turns to get from 0 to 127, and I can hear them clicking loudly through my headphones as I tweak a sound). I am using cubase and it receives midi from the knobs as I turn them but then what? the xpander receives pitchbend and modulation from the wheels ok but how can I tell the xpander to take data from a knob and map that to the (say) resonance. Can somebody point me in the right direction on this?

I hope I'm not asking a dumb question but I find all this VERY confusing!
Thanks,
Nick
