Can M-Audio Radium act as a piano apart from the midi controller function? If not, what has both facilities?

I need an instrument that can act as a piano/keyboard (able to play without being hooked up to a PC) and also a midi controller with the pitch bend and modulation wheels. I wanted to buy the M-Audio Radium but I'm not sure if it can act as a piano. I need suggestions. Also, if the instrument suggested has a head-phone jack, that will be a biggg plus. Thanks for your time.Can M-Audio Radium act as a piano apart from the midi controller function? If not, what has both facilities?
