Point of Instability

Born out of a meeting with synth Serge at the Erkki studio of Sibelius Academy in Helsinki, Pointof Instability is a study in micro: microgestures, micro-rhythms, microsounds, and microvariations.

A sonic portrait in black and white, a puntillistic flow in search of a purity of sound. The title has an autobiographical reminiscence and is related to the generating machine. Operating with a few patches, the slightest variation due to the shift of a potentiometer or one of the two joysticks can have dramatic effects on the sound. The goal is therefore to find a tiny point where the circuit is unstable and where anything can happen.
