Rhythm Games: Audio Cues

I am a very new user for Torque, so someone please inform me if we will eventually reach this topic when exploring the tutorials, but is there any information or any tools available to recieve audio based events in TorqueScript? I know that a lot of people have been working on rhythm games across the forums, but we don't know exactly how this is best done.

Our Goal:
The player presses a button within a given number of milliseconds of a particular sound playing in the BGM, an event is thrown.

I felt this was best handled by midi (That's how Guitar Hero does it), but even so, my team doesn't know what additional software is necessary, how much it will cost, and how much additional time it will take to develop.

Can anyone shed some light (or point to another relevant thread)?
