Every note on the retentional layers represents the starting point of a new cycle of the feedback loop that keeps the original note as a time object in memory. Lines connecting the notes illustrate the sequence of on- set repetitions per feedback loop. The crossovers of the sequences are based on the different durations within the original rhythm. This polyphony of retentional rhythms has a number of remarkable properties. All layers are different from each other. None of them is identical to the original rhythm Figure 3.
