trio (August 2013)
The second work in the pervado series, trio creates ambient music – with a twist of Eastern spice – that is structurally controlled by changing environmental conditions. Data from photoresistors, thermistors and motion sensors is continually polled to a Pure Data patch, where a network of intricate mappings is used to control the development and movement of the music. The project files can be accessed at Bitbucket; they are distributed under a Creative Commons Licence.

pervado – the latin term to pass through, penetrate, reach – is a set of works that use changes in local environmental conditions to generate and structure musical material. Influenced by Brian Eno's ambient music concept, works of the series all use sensors to poll data from the surrounding environment and create a soundscape that is unique to the current locale. Sensors include photoresistors, thermistors, PIR motion sensors and humidity sensors. Data from these are mapped various parameters that control rhythmic, melodic, harmonic, timbral, textural and structural elements of the work.
