Cool tech demo, not even close to a level quality I'd consider paying for
I agree that the quality isn't ideal, but I think this tool helps artists iterate much faster and cheaper. I wouldn't focus on the quality of the output, beyond the threshold which allows the artists to generate a reasonable idea of what they eventually want to make. Think about all the hard work that traditionally goes into composing a single title. Artists will spend days, weeks and sometimes months trying to itera…
I find this very useful as someone who's just learning how to play the guitar. My knowledge of music theory is still limited, and it'll take me years to get to a place where I can express myself in a way I'd deem "satisfactory".
