I have a Mackie DL16s that I am trying to multitrack into Studio One 5 Prime. For some reason it will only recognize 2 channels and will not let me add more. But, when I open Studio One 2, it works fine and I can see all 16 channels. Anyone know what is different? with Studio One 5 vs Studio One 2? I tried this with and without Universal Control installed and it behaves the same way. I also have the Mackie driver installed already. Thanks!
