Rupture d'équilibre


The main source behind "Rupture d'équilibre" is a computer program I designed to simulate the behavior of a pendulum. The program lets the user assign a mass to the pendulum, define the forces which will drive it and a damping factor, allowing the user to access all the pendulum parameters in real time. Its position and speed are then used to drive all kinds of MIDI devices, from a sampler to signal processing units.

The idea was to get the feeling of a "real" event occurring, and perceiving it through the sound it makes. Random forces may be added so that the equilibrium is disrupted, and real-time fader control is used to change the state gradually or abruptly.

Depending on the parameter's values and on the sounds used, the results are sometimes quasi-organic, sometimes pretty cold and inhuman.

 An hypnotic swing plays hide and seek with sounds and memory, creating an atmosphere where nothing remains certain...

"Rupture d'équilibre" (First version), composed at ARTeM studio, was premiered at the 1994 Festival Ars Musica in Brussels, Belgium on the 27th of March 1994, and was finalist at the I. Concorso Internacional de Musica Eletroacustica de Sao Paulo 1995 (Brazil). "Rupture d'équilibre" (Final version, March 1997) was premiered at Discoveries XXXVI in Aberdeen, UK on the 21st of May 1997 and was finalist at the Musica Nova competition (Czekia, 2000).
