I wrote the software for a physical sequencer as part of Yamaha/RCA’s exhibition at Chappell’s of Bond Street. It was Giuseppe Guerriero’s concept and Stefan Dzisiewski-Smith did the electronics.
Basically it was a step sequencer with 7 rows of 8 cells. 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.
All these sensors went into a single arduino, then into a PC running openframeworks with an adapted version of thump, my iPhone sequencer.
Other news, I got onto the next stage of the Design London Incubator. 10 down 10 to go.
