I had to do a quick and dirty test to make sure that I could combine morph states with a biped and animation for one of my upcoming freelance projects. Here is the result: Happybox is not happy. As you can see it works, the morph targets are overlayed over the keyframed biped head movement without a problem. Just make sure you put the "Morph" modifier [u]under[/u] the "Physique" modifier and not the other way around. Else your morph will also transform your keyframed movement back to its own 0 state.
