Controller mode/ableton question

Hey there, forgive me if this is a dumb question, I'm very knew to the OP-1... I plugged my OP-1 into my laptop to control ableton and was hoping to be able to set up the mappings myself, I can get it to control a soft synth but when I put ableton into midi mapping mode I cannot map notes or knobs to anything. I know there is a predefined script but can you set it up as you would another midi controller and just set keys/knobs to whatever you want?

Thanks!

Oh, I should say, I put it in controller mode when I tried this

try op-1 mode

Thanks, I sorted it, I was actually just being stupid in the end, I had switched on the correct ableton live settings. Thanks for your help
