I have seen the new announcement on the front page of the main site (Regarding the use of AI in metal music), and I agree for the most part. But I have a hypothetical situation, one that some might find a little stupid, but to me it is a burning question.
If a metal band used Vocaloid (vocal synth program) for its vocals, would that be considered use of artificial intelligence?
- The vocals are not technically human, yet they are composed by a human.
- There would be no proof that the band played live at some point, because, well, the vocalist is a program.
But, if the instrumentals of the songs were preformed by humans, and the vocals are the only things done by a computer, would it be considered use of AI or would it be perfectly fine?
Again, just a hypothetical question. :D

I think you need to realize first of all that Vocaloids are in and of themselves not AI technology. The user still needs to input their own musical compositions, tuning, and lyrics. Vocaloid is no more AI than your typical piano synth programming.
