Coin Sequencer is a physical interface for sequencing audio samples. It uses four IR transmitter/receiver pairs to detect reflective objects (such as coins) passing under one of four tracks. When such an object is detected, an audio sample is triggered on the computer.

I have a suggestion for placement of the coins. If you were to get a piece of paper or felt (non-reflective of course) and draw lines evenly across to show the actual beats, it would be easier to place them accurately. you could even make some for 5/4 or 3/4 times.

Out of all the MIDI sequencers i've seen on Hack-A-Day, this (analog!) sequencer has got to be the most original yet! love it!
