@gsagostinho Thank you for your comments about the music. About the L system, it was chosen the simplest one 010 where 0 leads to 01, and 1 to 0. The next iteration (01001) was the one that is mostly present in the composition.
The first part that last until 1:48 min approximately the L system is present by way of contraction of the chords (0) and expansion (1). The chords itself are not chosen randomly by the computer, let's just say that I manually choosed them respecting the 01001 pattern.
The next part which starts aproximately at 2 min and last until 3.25 min it is a sawthoot wave modulated and again the 01001 is present which 0 means descend and 1 ascend in the index of modulation.
The middle part where the single sawthoot wave is making its solo the 0 means descend and 1 ascend in frequency. And the other chords are controlled by the same rule of the very first part of the composition.
The last part which starts around 5.14 min has an algorithm to generate sound until it starts to make foldover which randomly selects pitches respecting the pattern 01001, with 0 descend and 1 ascend.
I hope this explanation help to get a better picture of whats happening in the composition. And thank you again for you interest!
