This is an in-depth tutorial on the Pure Data software program. It is a completely text and image tutorial and is organized much like a textbook. Will take significant time to go through, but if you have little understanding of what PD is, this is a good place to consult

This is a good intro video to pure data. Shows you the process of making a sound and connecting objects. Does not provide much background as to what objects are, what objects are available, or how to when to use different objects, but it is a good way to see PD in action
