Sá, Adriana2014Sá , A 2014 , ' Repurposing video game software for musical expression: a perceptual approach ' , Default journal .1646-3730Proceedings of the International Conference on New Interfaces for Musical ExpressionThe article exposes a perceptual approach to instrument design and composition, and introduces an instrument that combines acoustic sound, digital sound, and digital image. We explore disparities between human perception and digital analysis as creative material. Because the instrument repurposes software intended to create video games, we establish a distinction between the notion of “flow” in music and gaming, questioning how it may substantiate in interaction design. Furthermore, we describe how the projected image creates a reactive stage scene without deviating attention from the music.
