I'm a bit new to Processing. I'm coming over from the Arduino IDE, so it's a bit familiar, but still new to me.

Anyways, right now I only know how to make boxes and move them across the window.   Anyways, for a project, I want to be able to control iTunes with processing, so that I can use an Arduino to control it directly, rather than via infrared. The app could make a keystroke to control iTunes, or controlling it more directly somehow would be good too. I would like to be able to change the track, pause/play, and adjust the volume (in iTunes, or my Mac volume) And yes, I am using a Mac for this project, running 10.7.2.

Also, is it possible to check on iTunes, to see if it's playing music or not, or even if it is running? This would be very useful, giving my app some feedback instead of blindly pressing buttons.

Any help would be appreciated 

Thanks,
