Reply to Midi-fighter midi signals

Is there anywere I can find a detailed explanation on what midi messages the buttons on the midifighter sends in 4 banks mode.

The reason I ask is that I have been looking at the TSI for instant gratification, and it seams to have more then 12 different midi note on/off messages for each bank. How can that be done with 4 bank buttons and 12 other buttons?

Best Regards
