I'm reawakening this thread because this has been a constant battle for me... sometimes the Metronome works just fine, then the next time I go to record I spend the first hour of the session fighting to be able to hear it. All the settings look right, always, should be pretty straight-forward... sometimes I can only hear it through the headset, sometimes not at all... if I choose MIDI, the click is recorded on the track I'm using that doesn't help. I could just record several minutes of that and use it, but I don't prefer it, I really would like to figure out how to use my audio Metronome consistently. I can hear my keyboard just fine... any more thoughts? I can't imagine having to reinstall the X3 patch occasionally as a solution.
