Reply to stepsequencer in ableton with midifighter?

hi,
i just ordered a midifighter and have some questions:
1. what are the 'digital inputs'? i wanna use the midifighter for note input in ableton live and will need the four banks mode to access more notes. four banks external seems a bit more usefull but how are banks switched from the 'digital inputs'?
2. is it possible to switch banks with the supercombos?
3. is there some mapping(or m4l) to use the midifighter as a 16 stepsequencer in ableton?
4. can i set the midifighter to sent note events on 'all' midi channels?
5. is communication bidirectional so that the leds light up when a selected midiclip is running?
thanx,
gee hgt
