Apple's announced an interesting feature in a Logic update due very soon that will allow you to seperate a fully mixed track into stems based on instrument type. I've messed around with some of the AI based tools currently out there and know there are some more serious options available even now, it's kind of wild to see tech able to reverse engineer a track in this fashion.
A use case that facinates me is, imagine you just put up some sort of stereo mic to record your band jamming and capture everything in the rawest most live fashion possible. Then, drump the track into Logic, pull it apart and polish it as needed. If "Stem Splitter" can do this, that's pretty worthwhile.

Re: Logic Pro Stem Splitter
This tech has been around for a little while now, usually in expensive restoration suites like iZotope RX.
Like many miracle drugs, it can sometimes work well enough to broadly accomplish what it says on the tin, but there are some trade-offs.
Of course we'll probably start to hear more and more of those unintended behaviors, and they may wind up interesting, and in 20 years people will be seeking them out and copying them...

Re: Logic Pro Stem Splitter
This would be cool for bootlegs. Boost/clean up parts. (autotune if it's siouxsie).

Re: Logic Pro Stem Splitter
I've done some cursory messing around with Stem Splitter. It works although as one would expect: not perfectly but still quite good. I took a track from an album I worked on and when all the now separated stems were played together it was like nothing had happened. Individually, the drum, vocal and guitar stems came out well with some modest artifacts, while a very full range bass track fared less well, when heard in isolation.
I can see a lot of different applications. In my case I'd been doing some work where I'd recorded in a single track a drone with playing over top, as it was all coming off the same pedal board. I can now break that up and as long as I keep the two tracks playing it will still sound pretty good, I'll just be able to properly mix the once joined components. Stem Splitter would also be very useful to strip the drum track out of a mixed track, convert that to MIDI and remap to the drum sounds of your choice, and capture the performance in better fidelity. I'm also weighing how I can use this to clean up a bunch of old boombox band practice recordings.
As someone who once paid a grand for Logic 20 years ago when barely anything was included beyond the DAW itself, it's pretty wild you get this tech for a $200 now.
