Shared Buffer #X will be a live coding improvisation by a quartet of globally distributed performers (Bergen, Norway; Sheffield, UK; Hamilton ON, Canada; Montreal, Canada), all working on a single piece of shared code. The performance uses Tidal, a mini live coding language that represents polyphonic sequences using terse, highly flexible notation, providing a range of higher-order transformations. The performers are connected via various pieces of software for Internet-mediated sharing and collaboration, including parts developed for this ongoing project. Shared Buffer Study #X is part of a series supported by the research project “Live Coding and the Challenges of Digital Society” (McMaster University Arts Research Board).
