My interface is a Focusrite Saffire PRO 40. The input tabs are already selected in the song setup menu, but still the track is not arming any more. It used to work fine until i had to change my mother board and reinstall all my software. I think i have two installs of PreSonus studio One 4 Pro left. Everything is fine otherwise.
Thanks.
