As a part of Yamaha/RCA's "Making Fun Serious" exhibition at Chappell of Bond Street (a big old music shop),Â Marek Bereza created this sound sequencer installation which is controlled by reactive nodes spread across a two dimensional mesh. There were 8 steps in the sequence and 7 different sounds. Each cell has a depth sensor with which you can turn the cell on or off. The cells each have a light indicating whether they're active or not and a light indicating the which part of the sequence you're on. The concept belongs to Giuseppe Guerriero and the electronics hardware was done by Stefan Dzisiewski-Smith.
