Neurime
- an instrument inspired by neural networks -
Eszter Ozsvald, Michael Rosen

Neurime is an adaptive large scale instrument inspired by neural networks.

The interactive system perpetuates both individual and cohesive growth. Each neuron, represented by a discrete audio channel, changes in complexity with the frequency of its activation; through additive synthesis and modulation, each oscillator's resonance can evolve or devolve. As a system, the instrument learns each neural connection. A neural connection is established when two or more nodes are activated simultaneously. Their relationship is indexed, including hierarchy of strength through the connection's distance.

Neurime also has a memory for patterns and rhythmic gestures. While a neuron is held, it will dynamically store the activation of others. If that same neuron is held again, the pattern will be repeated until released. As the performance or installation progresses, each individual story evolves.

My first "acoustic" guitar. The idea was to explore how spiders feel the resonance of caught pray in the mesh. The hexagonal wires are in different potential; once the guitar string is pressed towards hexagonal wire, the exact location can be sensed and mapped. An additional piezo transducer is used to pick up the string's vibration.
While playing on the guitar, a corresponding bug-noise is generated; ultimate conversation between predator and pray.
