Iannis Xenakis e il sistema UPIC

UPIC is a computerised musical composition tool, devised by the composer Iannis Xenakis. It was developed at the Centre d'Etudes de Mathématique et Automatique Musicales (CEMAMu) in Paris, and was completed in 1977. The name is an acronym of Unité Polyagogique Informatique du CEMAMu. Xenakis used it on his subsequent piece Mycènes Alpha (1978), and it has been used by composers such as Jean-Claude Risset (on Saxatile (1992)), Takehito Shimazu (Illusions in Desolate Fields (1994)), Aphex Twin [1], and Curtis Roads.

Physically, the UPIC is a digitising tablet linked to a computer, which has a vector display. Its functionality is similar to that of the later Fairlight CMI, in that the user draws waveforms and volume envelopes on the tablet, which are rendered by the computer. Once the waveforms have been stored, the user can compose with them by drawing "compositions" on the tablet, with the X-axis representing time, and the Y-axis representing pitch. The compositions can be stretched in duration from a few seconds to an hour. They can also be transposed, reversed, inverted, and subject to a number of algorithmic transformations. The system allows for real time performance by moving the stylus across the tablet.

Blair Neal - Color a Sound

Color a Sound is a sound installation by Blair Neal, that invites participants to color on a transparency and hear a corresponding sound. Sound is triggered when it passes a line, observed by MaxMSP software running in the background. Different colors control the octave of a note, blue – low, green – middle and red – high. Modes can also be changed so that blue colours trigger 808 drum sounds instead of chimes.

The interaction is meant to be very simple and playful, hence the major scale. It would be much more difficult for someone to walk up and have fun with a chromatic scale. Like any instrument, one would have to spend a lot of time to make a composition worth listening to and this is just a demo of the sonic abilities/responsiveness.
