Can you class auto-tune as an instrument?
Chuck that in the bin with bagpipes too
There’s loads of post production tools for cleaning up the sound in the mix. I think things like auto-tune and quantise are a bit of a cheat, you are either in tune and in time, or you’re not.
that said, with things like drum machines, MPC’s etc some artists have deliberately bypassed these functions to create some great organic sounds.
you probably know all about him bro, but J Dilla was a pioneer for creating offbeat rhythms with his MPC, simply because he refused to be confined by the quantise function.

It was before your time on here. But HIAG lost his **** when he found out I was a gigging musician.
