I’m looking into building a simple tuio dj interface in Max/msp. I looked into Mathieu Chamagne’s excellent MMF project, but I want to go without video projection (just a wacom tablet or maybe wiimote on my main screen). The main problem for me is figuring out how to handle the inputs, in particular the rotary encoders. You would, I imagine, need to track 2 cursors and decide if they are moving in a “circular manner”, whatever that means in mathematical terms. I tried reverse engineering MMF, he seems to be doing a polar<>cartesian conversion, but I don’t really see that solving the problem.

Many thanks in advance for your time and assistance
