Another AI app that is in the works at YouTube is called Music AI Tools. This one relies on the user supplied vocal sample, that it can morph into audio of different styles. For example, you can upload a vocal sample of yourself humming a tune, and the Music AI Tool will be able to convert that into a guitar strumming.
There are a few images online showcasing what the interface of this tool will look like. There is not a lot of noise about this at the moment as YouTube has confirmed that it is still in its nascent stages and there is still some work to be done.
