Lego Techno Midi Hack 2014 NI MASCHINE controlled by Lego brick sequencer, controller

A quick video from MidiHack 2014. 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. Made at MidiHack 2014 at Spotify HQ, Stockholm. The Team: Tobias
