Feline Dreams is a iOS Synth One single pass piece tuned in a 12 note harmonic series segment using the arpeggiator and hold button.
Collaboration between Paul H. Muller and myself using a similar harmonic series tuned Synth One patch (click on the cat to get to the Audio Kit page) in a semi-aleatoric composition – Paul provides a server he programmed that uses the rules of Terry Riley’s score notes for In C to sequence 6*4*8 measures of music in vertical and horizontal layers.
