If it does the arranging for you, I wonder if it could work like BIAB--you choose your ensemble and style, chord progression, perhaps a melody, and it creates the orchestration for you?

If not, if one has to enter all the notes it will play, then I don't see how it is doing the orchestrating for you?

If it doesn't do that, it would be nice if there was a product that did---like BIAB for a full symphony orchestra, or a section of one.

Not that that would replace orchestrations done by humans, as BIAB does not replace human musicians.

But it could be a useful tool/
