Work in progress paper.
In this work-in-progress we introduce our prototype, a portable speaker augmented to be used as an electronic music sketchpad which allows musicians to play, record and compose multi-track music on the fly. We developed the MusicFabrik cover for the portable speaker, a playable textile cover which, although in functional sketch stage now, shows promise of becoming a useful tool for impromptu loop creation and collaborative music playing. We present our initial user encounters of the sketch. See video:https://youtu.be/pe2QaYv1Imo.
