Themain source behind "Rupture d'équilibre" is a computer program Idesigned to simulate the behavior of a pendulum. The program lets the userassign a mass to the pendulum, define the forces which will drive it and adamping factor, allowing the user to access all the pendulum parameters in realtime. Its position and speed are then used to drive all kinds of MIDI devices,from a sampler to signal processing units.
Theidea was to get the feeling of a "real" event occurring, andperceiving it through the sound it makes. Random forces may be added so thatthe equilibrium is disrupted, and real-time fader control is used to change thestate gradually or abruptly.
Dependingon the parameter's values and on the sounds used, the results are sometimesquasi-organic, sometimes pretty cold and inhuman.
Anhypnotic swing plays hide and seek with sounds and memory, creating an atmospherewhere nothing remains certain...
