I am looking for a good model for creating professional accompaniment for a melody line

I am looking for a good model for creating professional accompaniment for a melody line.

It might be something MIDI related in my collection.
This is a collection of Spaces, but if you find Spaces, you can find the models used.

Whole HF MIDI Spaces

Thank you for the suggestions, I have looked through some of them. I am looking for a model that will convert midi into a professional piece of music with accompaniment, but without the leading voice. A violin teacher needs a backing track for a student, an accompaniment for the piece that the student is performing.

I found something like that.

The second space was down with an error, so I duplicated it and it worked.
By the way, it looks like HF is doing server maintenance right now, and I tried to trace the model from the source code, but I get an error.
