ok, so i'm trying to create a motion tracking system using two microphone inputs(using a 4 channel mic pre on Windows XP) and a GEM with just a small moving sphere. The idea is to have the sphere move on the x axis depending on the volume levels of each microphone.(ie. as the volume increases on the left microphone, the sphere moves left, and visa versa). So far I have created a very crude version, but I am using two separate Pd consoles to separate the audio outputs, therefore I have two separate GEM screens with a sphere in each. Ideally I would like to have one GEM screen with both mics effecting the single GEM. Is this possible, or am I stuck with two screens.

Thanks guys, that helped tremendously. I attached the audio patch if anyone is interested.
