I created two Unit Generators, a Saw-wave Oscillator and Phasor; they were both patched through chorus and reverb effects before chucking to the DAC. The depth of both chorus effects was controlled by a random number generator, as was the frequency for the chorus on the Phasor.
I used the data set of Sheep in Australia & New Zealand as provided by the Time Series Data Library. I copied the first ten data values and pasted them again at the bottom.
