Arduino to Ableton Live

Hey guys, I've been working on a project to try and get temperature controlled sound using arduino and ableton, from my understanding I need to use a chain of programs to get this running, but the code is eluding me thus far.

I believe I'll need to have Arduino > Processing > An osculator > Ableton

If anyone could give me some tips / tuts to achieve this it'd be great.

If you have code please post it as it makes it easier to debug.

Furthermore: what is abletron? Do you have an URL or datasheet or ..?
