Using drawings and a guitar pedal to create one-man-band music: the Illusio

This paper presents a new digital musical instrument, the Illusio, based on an augmented multi-touch interface that combines a traditional multi-touch surface and a device similar to a guitar pedal. Illusio allows users to perform by drawing and by associating the sketches with live loops. These loops are manipulated based on a concept called hierarchical live looping, which extends traditional live looping through the use of a musical tree, in which any music operation applied to a node affects all its children nodes.
