This piece is written by Joshua Haagen, and is published with the composer’s permission. It was originally written for Saxophone Quartet and drums, but I have converted it to run on Sonic Pi and use the internal :dsaw synth to voice it, with some reverb and wobble fx applied. The midi drum track was modified to audible notes, which were then read by Sonic Pi and used to select suitable percussion samples to play. I like the strong rhythms and the intricate parts, especially at the start of the second section (after the bar rest). The code can be downloaded from my gist site.
