Motion detection to midi with puredata

another experiment with puredata, webcam image is passed through pix_movement object and a pix_blob turns the result into two midi note streams which are sent into reason via midi yoke. the image is the output of the pix_movement (difference between frames)



I put the pd patch at http://sites.google.com/site/skriyl/Home/pd-projects (motion noise.pd)



The patch outputs on midi channels 1 and 2. I used midi yoke and PD's midi output, then piped this into propellerheads reason, where you can use the "advanced midi" to set up midi bus A then lock down channels 1 and 2 to specific instruments in the rack. I used an NNXT with glockenspiel patch and nn19 with strings patch

First play with PureData

I was thinking about making a midi "harp" and thought of trying with a webcam, using puredata to analyse the images and generate midi/sounds. This is the first time I have played with PD and I don't really know what I am doing with it yet... you'll see I am not quite there with the midi harp yet, but I am impressed with how quickly you can get something fun working in PD



Here is the PD sketch, which I got to by hacking about with one of the GEM tutorial sketches
