I just love how versatile Sonic Pi is. Having moved from setting up my Glockenspiel, I chilled out with some Bach on Sonic PI, but then moved on to play with my polyphonic midi input program. I played around with some chords and found a progression I really liked. I did some further composing with my keyboard, and played around with the sequence playing at different pitches, and altering the octaves of the parts. With added gverb and using the :blade synth I found the whole sequence very hypnotic. You can listen to it here.
