Kinda off-topic, Rock Band 3 Keyboard Algorithm

[sdasda7777]

Hi, could anybody who knows how Rock Band 3 Keyboard key transmision works explain it to me?
My MIDI doesnt seem to work, so I want to create program to emulate it, but there doesnt seem to be any system in the way keyboard transmits keystrokes in form of Analog sticks and Triggers.
Thanks

PS: I know its not PS related, but I think this comunity is the one to know something about it

PPS: PS is AWESOME, GREAT work
