Motion Tracking to Sound or MIDI.

Hi there,

I'm new to Max and needed some advice.

I am trying to achieve this: http://www.youtube.com/watch?v=KPI41zKYxUE&feature=channel_video_title

Just a simple means of webcam tracking to create sound. I understand libraries like cv.jit will be involved but are there any important steps I need to take into account in order to make a working version of this?

Any help or advice is appreciated and apologies if a similar thread has already been made. Very interested in this area of work.
