Emerald Tablets revitalizes discarded interfaces, digitizing tablets from 1996, with custom software running on embeddable, single-board computers. The performer’s drawing gestures are mapped to feedback-driven synthesis networks and signal mixing procedures with further control and processing with a MIDI controller and guitar effects pedals. It is an improvisational piece where the performer learns the gestural correspondences to sonic circumstances while playing; and drives the piece forward based on emergent dynamics. A primary aim of this work is to explore new directions through resuscitating old interfaces categorized as deficient or electronic waste. This work passed peer review and was performed at the International Conference on New Interfaces for Musical Expression (2014 Goldsmiths, University of London).
