Cubase LE level indicator.

Started a new project, added an audio track (like I usually do) plugged in guitar and when I pluck the strings the output activity indicator lags what I’m actually playing. I’ve used this software and Lexicon Omega interface for a long time. Its perfect for what I do. I checked to make sure the interface was correct in Device Setup. Can any one help? Thanks

What is your Input Latency in the VST Audio System? What do you have the Monitor Mix knob on your Omega set to (9 o’clock, 2 o’clock, etc)?
