Exploring Situated Stabilities of a Rhythm Generation System through Variational Cross-Examination
It addresses the problem of understanding how digital musical instruments adapt to different contexts for designers and researchers, but it is incremental as it applies an existing framework to a specific case.
The paper investigates GrooveTransformer, a real-time rhythm generation system, by applying Variational Cross-Examination (VCE) to analyze its deployment in three artistic contexts, identifying key factors like system invariants and collaboration that led to its versatility.
This paper investigates GrooveTransformer, a real-time rhythm generation system, through the postphenomenological framework of Variational Cross-Examination (VCE). By reflecting on its deployment across three distinct artistic contexts, we identify three stabilities: an autonomous drum accompaniment generator, a rhythmic control voltage sequencer in Eurorack format, and a rhythm driver for a harmonic accompaniment system. The versatility of its applications was not an explicit goal from the outset of the project. Thus, we ask: how did this multistability emerge? Through VCE, we identify three key contributors to its emergence: the affordances of system invariants, the interdisciplinary collaboration, and the situated nature of its development. We conclude by reflecting on the viability of VCE as a descriptive and analytical method for Digital Musical Instrument (DMI) design, emphasizing its value in uncovering how technologies mediate, co-shape, and are co-shaped by users and contexts.
