Lauchpad for effect rack

My dream would be:
Controlling specific parameters on specific tracks with a lauchpad, and with light feedback.
For exemple, controlling a looper on track 9
1 pad for Rec button = Red light
1 pad for Play button = Green light
1 pad for Dub button = Yellow light
1 pad for Stop button = White light
1 pad for x2
1 pad for /2

I dont understand how to proceed…….

Thanks a lot
