I watched this Kenny G. video this evening, thanks for posting Dan.
Years and years ago I heard somewhere that pro mixing engineers would do this for their clients; basically stich together the best parts from multiple takes.

Fast forward to now where I've never personally done this, but play my bass, keyboard or drum pad thru the entire song and if I sufficiently mess up (which is often), then that Take gets deleted and I start over.

But here is where some enterprising programmer could make his/her mark. Imagine if a DAW could have a knowledge of timing and pitch mistakes and that I've made a handful of takes on say, the bass. It would start by analyzing Take #1 and stop at the 1st mistake it found. It would then scroll thru the other Takes to find the best section to replace the problem area. It would then continue in Take #1 and repeat untill the entire bass performance has been optimized on the minimization of errors by stiching together the best from all the takes similarly to what Kenny is manually doing in Reaper. I'm not even sure if AI would be needed for this.

Truth be told, I have somewhat mixed feelings about this. On the one hand, I'd end up with some pretty good and error-free final bass recordings. But on the other hand, would the final result really be "me"? And how damaging would this be to my playing ability?

This idea reminds me of Auto-Tune so maybe this has already been implemented?

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
