I made an interface on Mrmr to emulate a controller to play games. I would like to use the xy pad to control the mouse position. Is this possible, and how can I do it?

Also, I can probly figure this myself with a bit of thinking, but how can I map buttons on Mrmr to keys on the keyboard? I am using udpreceive and routeOSC for all of this.

I realized how little info i actually put there. im running on OSX and Mrmr is on the iPod Touch. I can read the messages sent from Mrmr and from the mouse and keyboard. I just dont know how to map the OSC messages to the Keys and Mouse.
