Same problem, bro.
My ATOM works well with other apps like Melodics, but when I start S1, pads and buttons dont change the color if I navegate or I change instrument (Impact, MaiTai, etc). Its supposed that ATOM change the colors for visual guide of what Im doing
I tried to "reconnect" in "external audio devices" but just change the color of the pads to the state in these moment and keeps static untill I click "reconnect" again (Ex. If Im using MaiTai and I click on "reconnect", the colors of the pad change to black/white keys mode, but if I change to a Impact the colors keep the black/white keys mode.
Pls help :C
