Johan Eriksson is a music-maker currently writing his PhD at the Birmingham Conservatoire (UK) in the field of composition through modular synthesis and live-patching. Particular interest lies in the Pure Data programming language. By blurring the lines of composition, performance and instrument design his work explores novel outputs for music made with modular synths. Based in Stockholm, he collaborated with Swedish synth company Teenage Engineering in 2014 developing software to control their OP-1. That project grew into a virtual modular synth in Pure Data called Xodular which was given a warm welcome by the community. Recently Eriksson has been exploring live-patching in Xodular and begun the development of a dedicated hardware interface.
