Vodhrán: collaborative design for evolving a physical model and interface into a proto-instrument
Bibliographic record
Abstract
This paper reports on the process of development of a virtual-acoustic proto-instrument, Vodhrán, based on a physical model of a plate, within a musical performance-driven ecosystemic environment. Performers explore the plate model via tactile interaction through a Sensel Morph interface, chosen to allow damping and localised striking consistent with playing hand percussion. Through an iteration of prototypes, we have designed an embedded proto-instrument that allows a bodily interaction between the performer and the virtual-acoustic plate in a way that redirects from the perception of the Sensel as a touchpad and reframes it as a percussive surface. Due to the computational effort required to run such a rich physical model and the necessity to provide a natural interaction, the audio processing is implemented on a high powered single board computer. We describe the design challenges and report on the technological solutions we have found in the implementation of Vodhrán which we believe are valuable to the wider NIME community.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
