Maschine/Traktor LED mapping help needed please.

Hi everyone, I'm having trouble with some LED mappings and hope someone can help me out.

1, I have 4 buttons that each put one of the 4 decks into focus. How can I output LEDs to the 4 buttons to show when a particular deck is in focus?

2, I have a shared 'Play' button ie. you press one of the deck focus buttons I described above and simultaneously press the play button to get a deck to start.
Now what Im trying to do is, when you select say 'Deck A Focus' and that deck is playing, I would like the 'Play' button to flash. But then if I change the focus to deck B and deck B isnt playing, then for the flashing to stop.

3, Is it possible to output a flashing LED to show when a deck 'Is In Loop'?

Many thanks in advance guys!

Great. I ask for some help with LED mapping and get spammed with some crap about Family Guy.

I'm still looking for help btw, just something relevant to my post. :)
