I know the conversation here has run its course, but I just wanted to add: whether or not Emily Howell is seen as something that "works really well" as an automated system is probably up for debate.

For example, one of the most popular pieces from Emily Howell is this fugue: https://www.youtube.com/watch?v=jLR-_c_uCwI - we really don't know how much influence Cope had in creating this piece of music, because the process of composition was not transparent at all.
