I had problems with a midi track not recording as what you’ve described. I had three tracks at 192kHz. One vocal and a pair of stereo keyboard piano. I had wanted to track the midi from keys but only managed to get one out of three takes through. I didn’t know this after the session. Thankfully the DI out from the keyboard isn’t “bad”. I can only guess it might be a driver issue. I have operated RME UFX and RME UFX+ from the PC laptop before and audio works as it should. (On a MAC however, I do have audio conflicts with having both UFX and UFX+ drivers installed.) What is puzzling to me is “two midi take” didn’t get through instead of all three. Could there be other settings that I’ve set wrong? What’s the difference between midi record and VSTi out record?
