So far I find Aria unusable

It requires me to select chords, so I select chords - and then it tries to overwrite them! And so far all of its suggestions have nothing to do with the chords selected, it just gives me back a seemingly random jumble. I haven’t figured out yet how to ask it for melody suggestions on selected chords, which is what I would be really interested to try. Is there a guide for using it? What experiences have other folks had with it? Thanks!

Hi, after selecting a couple of measures you have three options on what Aria should create for you: Chords, melody and both.
To get a melody for your chords, just use „Create Melody“.

Please let me know if this helped.
