I should probably share what I have mine at, just to help you along.
My Starting point for an ableton midi setup:
Midi preset 2:
All encoders set to continuous,absolute,midi ch2 (at first you might have to turn the knobs a couple times for the encoder to catch up) sorry I'm not a midi pro
Pads 1-16 are assigned to midi ch 3,midi note, gate, midi note 35-51 with 35 being pad 1 and going up from there.
Like I said, just a starting point. Far from ideal.
This setup allows you to control a synth on the keyboard and drums on the pads at the same time with out switching midi channels.
Hope that helps out a few of you.
