A work in progress based on a midi conversion using midicsv and Sonic Pi programs developed from ideas by Joe McCarty published on https://in-thread.sonic-pi.net/t/playing-midi-files-on-sonic-pi/358
Here I am experimenting with using differnt synths for different voices, adding fx-level commands to balnace the parts, and dupplicating the pedal part an octave lower. Some timing issues, but not a bad overall rendition. The piece is played entirely by Sonic Pi using internal syntsh :tri, :pulse and :saw. Also added gverb effect.

Sonic Pi plays a series of dreamy notes based on an A, which interweave, in and out of tune. Two relentless tones, a tb303 synth on A1 and a chiplead synth on A4 accompany them, together with some percussive drums, and the whole fades in and out of tune as it progresses. Here two complete cycles of the piece are played.
