Ruby patterns for contemporary dance music
summary
Claims that a complete dance track is possible with only Ruby code, not Sonic Pi; actual build is a tiny pure Ruby synth that writes web-playable sound files and a simple arranger. Uses square waves at 440 Hz, white noise, ADSR envelopes and a state-variable filter to sculpt timbre; models a snare by pitching a body tone up and mixing filtered noise; sequences via a 16-step step sequencer at 120 BPM and adds a ring-buffer delay for echo. The prototype runs and produces a recognizably rhythmic song though it’s rough around the edges.
