I think that if people get to have Universal Basic Income, and society can be arranged to provide it without causing big problems to society, then it doesn't need to be tied to Automation in any way, and instead can simply be viewed as a core benefit of being a member of society. That seems like a more elegant approach.
People would not want to be told 'oh, it seems like we are going to scale back automation some, so everyone is going to only get 50% of the UBI they have been receiving previously'.
Anything that is fun for you that makes musical noise is a good option for you! Presumably you are not attempting to be a world class music producer right away, and are more interested in having a bit of musical fun. Go for it.
