OpenCV and Python process a webcam video to recognize Lego blocks through a translucent Lego base plate. This is sent via OSC to a second computer running a sequencer that sends out MIDI into Native Instruments MASCHINE. Does step sequencing, filter on an XY pad, fader for beat delay and a rotary for even more reverb.
The awesome Team:
