Hi Torito!
Best way to do that is to send the data of the kinect to Smode through OSC.
I've find some app which could do the job:
Kinect
Some resources use Pure Data to get the data of your Kinect. I advice you to look at the doc about OSC in Smode. There is a tutorial of Vincent Le Moigne about the control of Smode with a Xbox pad a t the end (it's using Pure Data too).
Cheers!
