Quick question about a good robotic control software

Hey everybody,
Ive been toying around with the idea of casting one of my current sculptures in silicone and installing some servos in the head to give it movement. I have done a LOT of research on the subject and will be investing in a arduino multicontroller, which will power and control 4 separate servos. The problem I am having right now is finding an effective software to easily program all four servos to run at the same time and also incorperate sound, so that can be played back together to look like the character is talking.
I stumbled on this siteMini SSC II Serial Servo Controller/Robo-Ware Order Page,
but im a little wary since it looks like it hasnt been updated in a long time. If anyone knows software that is more up to date but has that same general purpose, I would really appriciate the help since this will be my first sculpture with movement and sound incorperated. Thanks!
