Wholeheartedly agree using computers as a compositional aide is a fantastic thing, it's really quite satisfying to define some rules by which the program can modify the inputs (melodies, chords, drum patterns) and have it output interesting results.

I coded up some jungle music not long ago: https://www.youtube.com/watch?v=GPan4gRSwZs&t=79s

I'm working on a procedure to modify the drum breaks in a conventional way, meaning I have to think less about keeping them interesting while live coding.
