I cannot hear audio play while I have midi instruments playing. I have a drum loop in ultrabeat and when I play my Roland fantom G8 thru input 1, I can hear sound when ultrabeat is not playing or when in record mode. I cannot listen to my drums and play the keyboard at the same time. All software is latest version. Other products Roland Fantom G8 with mono cord into input 1 of duet. logic Pro 9 Mac OSX Lion Apogee duet - maestro 2

Hey Jex, Glad you found the answer in a previous post! :)
