Hi Watson,

It looks like that "Monitor" knob is the volume control for the "Mon Out" outputs on the back of the MBox, nothing to do with input monitoring.

I'm not sure the MBox 2 actually provides hardware input monitoring. One review I found online said this: "The Mix control has gone and so the Low Latency monitoring feature is handled by the Pro Tools software, just as it is with the 002 and 002R interfaces." I also couldn't find any information in the MBox 2 Firewire's manual about enabling monitoring without ProTools.

If you open your Band-in-a-Box song in RealBand and do your recording there, RealBand can provide input monitoring, as long as you use an ASIO or WAS audio driver.

Thanks
