If it's over HID, it's a different story, though. Yes, it is only MIDI. The scenario is: 1) send a greeting message to the mixer 2) receive a greeting message 3) send another constant message 4) receive the response 5) compute something and send it back 6) receive the confirmation message 7) start sending a keep-alive message each 200 ms Specific received messages might be consumed by kernel (invisible for user-space), but others should flow undisturbed to the user-space. The sent messages should be injected and intermixed with normal messages coming from user-space. The kernel should not claim exclusive access to the MIDI device, because user-space tools might want to use it too. Is there already anything similar, for inspiration? Franta
