Ableton Forum

Hi all. I'm using Ableton Live 7, controlling it with an Alesis Micron on a Macbook. The Micron is working great as a keyboard controller, but I can't seem to map the xyz knobs and sliders. When I try to map it, it doesn't assign anything. On the other hand, when I move sliders & knobs I see the Midi activity in the top right indicator of Ableton Live. Anyone have suggestions as to what to try, to make this work?

Thanks!
