Webcam to Pd to VCV Rack

A little experiment with Pure Data (aka Pd) running a patch using a webcam for data input. Motion detection results in three sets of continuously changing values that are converted to MIDI note and controller data. The MIDI output is routed to VCV Rack for the final conversion to audio.

Pure Data with GEM is required for this patch, along with a webcam, of course. The original Pd patch for webcam to MIDI conversion can be found at My version of the patch is located at
