Is it possible to use a USB/Midi keyboard controller and detect which keys are being pressed?

Hi,

For my final year project at University I was planning on making a game that relied heavily on music to direct the gameplay. My question is, is it possible to detect keystrokes from a keyboard midi controller in Unity? I've been conducting some research and some people claim it is possible through various plug-ins although I haven't been able to find any concrete answers. Hope this is clear enough.

Thanks, Ed.
