InkQuencer is a step-sequencer that lets you make beats by drawing patterns on paper.

You play back the patterns by putting the drawing in front of a camera. The program receives the images from the camera and draws a saled down,  32 by 30 pixel isometric version. On each beat from the metronome, the  scrubber runs through a new column of pixels and plays a sound if the pixel is black.

“The InkQuencer creates a new way of interacting with a traditional electronic music interface,” says designer Sebastian Thielke. “The possibilities of playful and randomised music sequencing is taken back into the physical world allowing for a more direct tangible way of experimenting with sound and rhythm.”
