I just purchased the Cubase LE 4 bundle with OMEGA and Lexicon Plug in. I've just got it running, but I CAN'T HEAR THE CLICK FROM THE METRONOME coming out of the head phones. I called Lexicon Support and they can't seem to figure out what it is. I've checked all the settings and they are fine. I am running on a DELL Windows XP. Can anyone help?
