Sequencer Wheel

For the past month I’ve been working on a hand-cranked beat sequencer.  This device grew out of a bunch of ideas I’ve had while working on my residency at DPI.

In short, the sequencer consists of two large, concentrically-mounted wooden wheels.  One of the wheels rotates on an axle and the other which has sixteen sliding levers attached to its face remains stationary.  As the front wheel rotates, a switch mounted on its back is depressed by levers on the back wheel which have been pushed toward the wheel’s center.  Each time the rotating switch strikes a lever, a sample is triggered on the attached computer.  It is possible to play repeating sequences of samples by rotating the wheel at a constant rate.

The following video shows the operation of an early cardboard prototype:

Since shooting this video almost a month ago, I have been building a more substantial prototype out of wood.

Tonight, I’ll be testing out the wheel with the software I wrote before I made the cardboard prototype.
