Honestly, I have no idea.
The computer to the left controlled the huge LED-Wall running through the club.
OF COURSE I played around with it all night. It was able to display a huge equalizer (connected to the DJ mixer). Awesome stuff.
One little note to the small KORG nanoPAD: The pads are velocity-sensitive. I connected this value to e.g. the pixelate-size. Tha harder I punched on it, the larger the pixels got.
