The performance is generating music in real-time by writing code (Rust) into a Jupyter notebook. Using a notebook allows partial re-evaluation of parts of the program without pausing execution of other parts, allowing music to be seamlessly built up from simple waveforms to complex multi-layered soundscapes without periods of silence while my code recompiles. I use a synthesizer library of my own design - CAW (the Combinatorial Audio Workstation) - which allows synthesizers to be built in the paradigm of Functional Reactive Programming (FRP). The synthesizer library also allows a stereo-oscillographic visualization of the live output, and for live interaction via graphical widgets (e.g. knobs) in addition to responding to live code changes by (re)evaluating notebook cells.
