How do I get the knobs to work on my usb midi keyboard? (Oxygen 8)

I'm trying to interface my Oxygen 8 usb midi keyboard with some max patches. I've gotten it connected and able to receive note in values when I press keys, but I am hoping to figure out how to get Max to detect the knobs on the keyboard so I can use them to adjust different levels and effects in jitter and Max. Is there a way to detect these type of things on midi keyboards? Thanks
