Note that this is not yet available to the public but i assume will be eventually (although why someone would want to take something as rewarding as writing music and automate it is beyond me). Also, conspicuously omitted is any information on the training data which might be copyrighted?
Wow, that's very impressive. Another example of how things are likely to change. Creating complete 'songs' through singing could open up a huge area of new entertainment to rival Karaoke maybe?
