NONLINEAR – ‘‘Feedback-As-Instrument’’ (Work in progress)

Nonlinear explores the magic of unstable systems through audio feedback.

Nonlinear relates to the concept of no-input mixing board performances but uses a software emulation instead of hardware. No external sound source or soundgenerator is used.

Instead, an over-complex network of effect modules feed into each other, combined with mappings where each turn of a knob changes several tonal parameters simultaneously in different directions.

Where no-input mixing boards use the ground noise of the electronic circuitry, its digital pendant gets excited by malfunctions of software modules that produce bursts of sound in irregular intervals making it impossible to fully control the sonic events.

The artistic challenge lies in wrestling with a hard-to-control instrument, the poetry of the sonic outcome in its raw, rampant character full of insecurity and unpredictability.
