Live Coding Music with Ruby
summary
A Ruby gem called banjo generates live-coded music by loading channel classes and calling their perform methods on an EventMachine timer, using a 0–15 sweeping counter and modulus checks to trigger notes (e.g. play when counter % 4 == 0). MIDI output goes through udmidi to a DAW (Logic/GarageBand). Tempo maps to poll rate (60 BPM → 1s ticks; 120 BPM → 0.5s/quarter beats), classes reload live, and a live demo briefly freezes; Linux support and duration-as-fractions remain todo.
