I'm not understanding why latency should be an issue, especially since you have a M-Audio M Track interface.

The audio interface will combine the sound you are sending to the interface (typically microphone or instrument) with the sound coming from the computer (Band-in-a-Box instrument tracks audio output) and blend the two audio signals together for you to hear through the headphones. This is taken from the M-Audio website:

"Improved Monitoring for Better Recordings
M-Track offers ultra-low latency monitoring of the input signal—either through the speakers or via headphones. The monitor mix knob adjusts the balance between the direct inputs and the playback from your computer software. In addition, the input signal(s) can be monitored in stereo or mono using the convenient Stereo/Mono switch. This makes it easy to record new parts or add parts to an existing composition. The Headphone output offers its own level control."
