In my case, I built my own, through 10 years of organic instrumental input for the system to chomp through.
That's how you apply machine learning to the discipline of music.
It's also apparently wrong: https://magenta.tensorflow.org/datasets
Thanks for your contribution.
You say that I am applying a false premise and that I am apparently wrong -- but what kind of nonsense have those datasets output that comes even close to what I [0] have?
Also, you strongly misunderstand the value of having to build your own dataset of actual human input to achieve anything good in AI-assisted music-making. Good musical AI does not simply seek to mimic a dataset. That's such a pedantic oversimplification of this noble, difficult task that those of us who actually care about this issue face.
This problem cannot be solved like an object detection problem. You have a lot to learn before you start trying to insult those of us who have devoted much of our lives to the "problem" of AI in music.
This is art, buddy. Stay away from it if you are going to treat it like a mindless AI researcher at some institution.
