After I reopen a mix on Studio One 5, my Atom seems to work but when I open Impact to work on a track the Atom works with the mouse on the screen but no sound on the Atom when I touch the pads. The lights lite up correctly but no sound. I then tried to reconnect but no good. I unplug the USB cable and then replug and then it works with no issues until I exit and come back in to the mix. Not sure if there is a fix but if anyone has an answer, that would be great. Thanks
