I follow the right steps from the ableton manual I'm pressing midi then midi mapping shows up then I press a slider with my mouse and when I move that slider normally it would be assigned but nothing seems to happen ? The same happens for knobs.
In the akai mpk49 manual they say for editing the sliders you have to change the CC (controller number) but then i have to now the CC numbers they not talking about manually change like the ableton manual explains...
Has somebody the same problem getting frustrated about it...
