Just spotted this tangible step sequencer on Synthtopia, I like the way that the webcam is underneath so that it avoids occlusion problems. Nicely done – shame that the webcam isn’t also used to track different colours in the same way as the bubblegum or skittle sequencers though. The project was built using SensoMusic Usine.
