I have been using M Audio Oxygen 49 with no issues up until a couple of days ago. It began to not show up as a midi instrument. So I removed it and set it up again. However, now it does not show up in the Receive From button. Instead, my Focusrite 1820 shows up in there. This was not happening before. The controller is USB based and powers up when I turn on the computer. I have no idea why the interface shows up. The interface does not have a USB port to connect anything to it. Very confusing.
I am using Studio One 4
