It's More Fun to Compute
summary
Live demos show Ruby driving real synths via Ruby + Sonic Pi + MIDI using a small JRuby/DRb server that routes notes to Korg Volca and Minibrute hardware and mostly works despite occasional USB latency and GarageBand interference. A Ruby gem stack maps MIDI ports to YAML, a DRB MIDI router sends envelopes and chords, and a musical test reporter emits pass/fail notes; sonified algorithms compare bubble and quicksort and bubble sort oddly wins subjectively. Source code and demos sit on GitHub and the hardware setup is reproducible.
