Chamelon Guitar (by MIT Media Lab)

It’s a 99-in-one guitar. It has different small bodies, equipped with piezo sensors. They can get the resonance of the small body, and simulate that for the whole. I think this is a really simple, and pure idea, that is relatively easily implemented.

CATEN (David Letellier)

Created for the Saint Sauveur chapel in Caen, Caten is a levitating sculpture, determined by gravity and guiding the evolution of a sound composition.
300 wires suspended from two ropes, connected themselves at each end to a slowly rotating arm, form an evanescent surface which interacts with the architecture.

At each turn, the engines emit one of the first 4 notes of the scale (Ut, Re, Mi, Fa), creating a sequence of intervals, constantly reconfigured. Low frequencies resonate in the space and emphazise the transcendental character of a place once dedicated to faith.
The name is derived from the term catenary, which describes the plane curve formed by a rope hanging between two points.

Konkreet Performer

Konkreet Performer is a live music performance controller. It has a beautiful circular multi-touch interface that reconnects the musician’s actions directly with the music. Although their description sounds a bit too commercial, I think this is a good example of what’s possible to do with multi-touch devices.
