Building Beats

Have you been wondering what to do with all those Lego bricks you ‘grew out of’ a few years ago? Well, before you put them on ebay, why not try building your own beat sequencer. By combining those little Danish bits of plastic with the DJ software Ableton Live, SoundMachine converts the colour information of the bricks to generate a synthesised beat.

The creator uses Lego motors and a Java program called Processing to scan the colours that pass underneath to send MIDI messages to the software. It basically does the opposite of a graphic equaliser using Lego. Excellent.


We’re not sure if the sequencing capabilities stretch to Lego men and their tiny accessories, but you could always try… Just don’t get caught playing with your Lego by the wrong person!
