Sonic Pi - BEAM up the VJ
summary
Live‑coding music system evolved from an Overtone/Clojure prototype into a two‑week Ruby port for Raspberry Pi, using SuperCollider over OSC with timestamped scheduling to avoid GC jitter; concurrency is exposed as named live_loops so drums and bass run in time. Migration work moves IO and timing into BEAM/Elixir with C NIFs for MIDI and a Ableton Link synced metronome, and embeds Phoenix LiveView to drive browser visuals (Hydra, p5) for Phoenix LiveView driven visuals — used in classrooms and live venues successfully.
