This is a repository of various scripts I used to generate random sequences of notes for a music production I worked on! I used the mido python library to create midi tracks conforming to certain rules; the tracks sped up and slowed down, and varied in range of notes along with its speed. There were two kinds of sequences I was looking at particularly:
- Markov chains: I created a sequence of connected notes and assigned a transition probability in each direction, which I varied to increase and decrease "randomness". Here is what that looks like, where the initial and final segments have higher probability of moving toward the starting position:
- Random series: I generated random numbers between a low and a high value. I varied the width of the envelope with speed, as shown below:
While initially, the notes are quantized to the D major scale, this quantization is done away with halfway through with the intent of making an unnerving shift.
I then exported the out files onto a DAW and used them as a basis for my production! This repository also includes the final production output, created in surround sound but outputted in binaural audio.
