Proximity sensors trigger playlist and volume sliders / total neeewbie!

Hi everyone, trying to get my bearings around where to even begin creating an interaction that would:

1. Trigger a playback of 11 audio file playlist (all 11 at once) via touch board proximity sensor. All tracks have volume sliders and are triggered to begin playback at Vol 0.
2. Trigger Vol slider on Track 1 from Min to Max via touch board proximity sensor.
3. Trigger Vol slider on Track 2 from Min to Max via touch board proximity sensor... etc.
4. When all tracks have played out once - new track (one audio file) begins and plays out.

Would be v helpful to get some pointers where should I be looking to begin with this. Really clueless with this one, haha. All I have atm is a basic proximity sensor sending some FDAT to Max. So nothing really. This is my first interaction project ever.

Many Thanks guys
Xx
