This composition is generated by 140 characters of Supercollider code, or 124 if you exclude the hashtag. A recording of this code’s output appeared on the ‘sc140’ album compiled by Dan Stowell in 2009. The piece feeds a sawtooth wave into a feedback delay line, which contains a band pass filter and some distortion. These filter frequency randomly modulated at a rate that differs from the period of the delay line, resulting in syncopated rhythms and a continuously evolving sound. This is a new recoding, made in 2014. Because the piece uses random numbers, the two recordings are different, with the newer version happening to produce a noisier, more aggressive sound, especially towards the end.
