Upcoming publication @NIME on LoopBoxes - a modular set of tangible interfaces for digital musical instruments. We tested the LoopBoxes in two field studies, on a music festival and a school setting for children with special educational needs (SEN). People enjoyed playing overall, but we also identified some challenges when adapting the instruments for very specific user needs.
