This paper describes the ongoing process of developing RAW, a collaborative body–machine instrument that relies on `sculpting' the sonification of raw EMG signals. The instrument is built around two Myo armbands located on the forearms of the performer. These are used to investigate muscle contraction, which is again used as the basis for the sonic interaction design. Using a practice-based approach, the aim is to explore the musical aesthetics of naturally occurring bioelectric signals. We are particularly interested in exploring the differences between processing at audio rate versus control rate, and how the level of detail in the signal––and the complexity of the mappings––influence the experience of control in the instrument. This is exemplified through reflections on four concerts in which RAW has been used in different types of collective improvisation.
