MIDI to HID?

I've seen several programs converting HID (Controller) signals into MIDI.

I need the other way, i have a midi keyboard which i want to use as a controller.
Any suggestions?

There is a version of Bomes Midi Pro thats going to come out that will have this.
There are a heap of Lord of the Rings MMORPG players(never played it) that like to use their piano to play their in-game instruments and are using a beta of Bomes Midi Pro to do this.

LoLz... That's f-in brilliant... Using MIDI to play your MMORPG musical instruments. :D
