[2015 University Project] Parse MIDI text files and randomly compose new pieces through the use of a Markov chain algorithm.

Instructions

These instructions assume you already have the knowledge needed to compile and run Java source files.

1. Convert your .mid file to text using this free online tool with the "absolute" timestamp option
2. When saving to .txt, only copy the lines that are formatted as follows: 192 On ch=1 n=36 v=23 (for optimal results, parse and compose different instruments separately)
3. Edit the absolute file paths for the input/output files in the main function of Main.java
4. Set the composition's desired duration and speed progression by changing the parameters of the composeScore call
5. Compile and run the program
6. The score text file can then be used to make MIDI notes with your method of choice; an example of how to play the notes with Pure Data is provided below:
