Reply to Ableton drops

Hi im getting some trouble with my ableton for some reason it start to sound some audo drops from time to time in the basses and in the drums im using my m-audio my laptop works perfectly well with ableton but the last days i have some of thi problemsin my s4 too

Also another question about massive why some parameters move even i dont make any automatisation? its just continue moving some knobs that i have maped in my keyboard but i dont record anything
I hope someone had some answers thanks
