I did not downvote you but I think you are being downvoted because computer-aided music production and algorithmic music composition are two very different things; when using a DAW program, musicians still need to enter notes using some sort of GUI (nowadays the most common interface is called "piano roll")[1].

Algorithmic composition, on the other hand, is less common, and mostly relegated to avant-garde or art music, although there are examples in popular music such as Brian Eno[2].
