So the way that the light interface works is, there are 16 sensitive areas when they sense how bright the light is falling on them. The signal from that is read by this little computer which is called an arduino. When light falls onto one of the sensors its picked up and the brightness is showing on the screen here. And you can use that data from the light interface to control any parameter you like. When it’s bright it is just making a note loud and there are 16 different notes all over the interface So the actual thing itself is fairly simple but then it’s taken years to make sounds look like they belong to this machine. And the sounds can change, you know there’s different, I guess you can call them different instruments in the computer. So there is one which is tones and one which is noise and there is one which is rhythms and you can combine them all together. To me they’re like interfaces and instruments so I’ll make an input I’ll shine the light at it and it makes a sound, just like when you hit the drum or play the guitar DJ’ing is more working with pre-recorded material. This is generating things live.
