# Organum Vivum - a interspecies interface

Organum Vivum is an interspecies interface advantaging the characteristics of organic material as well as exploring the possibilities of combining natural and build organisms in sound synthesis. Bacterial cellulose items, working as sensors, are translating our direct interaction with them into a soundscape controllable with touch and breath. In order to communicate in human level through the instrument we’ll have to be aware of the behaviour of a natural material and it’s, sometimes unpredictable, responses to our actions. The result is a sonification of direct interspecies interaction between a human and a micro-organism.

The circuit has 5.1 k resistors as reference resistance and the analog input pins of the arduino as the input device. The values of the resistors were determined by purely experimenting, while having the openFrameworks application, PulsumOSC by Leslie Garcia, running. This way we were able to get some permanent values. The design of the circuit also made it necessary to implement four diodes.…
