My computer recognizes it but doesn't always send MIDI to my device. I tried plugging it into a powered USB hub but nothing. Tried to update drivers, nothing. I'm on OSX, for reference. The lights are on, the computer recognizes and sees the interface, the green light is on - but not flashing when notes are being passed. The problem does not occur with my other interface (Scarlett). The problem seems to go away when I restart my computer and open the DAW first, but comes back after exiting. I tried other DAWs. I googled the problem, other users report the same thing. Therefore, the problem lies in the interface itself.
