A REAL MIXER
Unlike standard computer I/O boxes based on a patch bay concept, the Lexicon Omega Studio is designed and built around the same paradigm as large-format recording consoles. An 8-input, 4-Bus, 2-output USB I/O mixer with inserts, instrument input, MIDI I/O and complete metering and monitoring functions gives you the freedom to record up to 4 tracks at once and mix without the need for additional mixing hardware.
This is what we're talking about. Play with the mixer and check the levels and balance. If that's ok then open up Cubase or whatever DAW you're using and check that balance as well.

Yup exactly. When you installed the software, it's very possible the mixer/control panel also installed but you didn't notice it because if it's like mine, it didn't create a desktop icon.
Look in the start menu and check for a folder named for the interface or something very similar. Open it and look to see if there's an executable in there. That's where my control panel was hiding. You can create a desktop icon from there.
