I wonder if any of those services can generate editable output for a software like Ableton or Logic Pro.

Seems to be more useful as an "assistant" for music producers, similar to how Copilot operates.

Google has actually released Magenta [0] which is a plugin within Ableton that can do just that. It's pretty cool, it generates interesting melodic content at the click of a button.
