I have a SpectraLayers 8 license. Not sure I know how to do this but I can give things a shot at some point with some effort and/or guidance.

Sure, this is possible in MAGIX Spectralayers Pro. And I assume in similar packages as well.

You would record the vocal melody from midi into a 'wav' type signal (available in several softwares) and insert it into a song in Spectralayers. You would then select this signal and its Harmonics (available in Spectralayers), cut it, paste it into a separate track, and Bob's your uncle.

The human voice is not perfect. The vocal will waver around a note/frequency unless it's a modern auto-tuned monstrosity. Unless your midi follows exactly every single human imperfection with pin sharp accuracy alongside its timing and with the exact same harmonics, It Isn't going to work particularly well.

Izotope RX pro has the ability to remove things like foldback and headphone spill, but both the source that fed the headphones or foldback needs to be available and in 100% sync for this process to work a fraction of a millisecond out, and it doesn't work so well the more out it is timing wise the wosre the results. - The same principle as above.

Currently when music is demixed it removes the sound and leave a hole where that sound was, so everything in the same frequency gets separated. Sound, when intertwined with many other things is far too complex for computers to simply separate anything you like. I think it will come, but we aren't there yet.
This conversation reminds me of the time Gilligan found the bush with the mind-reading seeds:
Professor: It's scientifacally impossible to read another person's mind!
Ginger: Go ahead Gilligan, read my mind for the Professor! Who am I thinking about?
Gilligan: Hmmmm...Rogery Hudpeck!!! Rogery Hudpeck???
Professor: See? It's Impossible!!!
Ginger: No! Gilligan's right...I couldn't make up my mind. I was thinking of Rock Hudson AND Gregory Peck!!!

I agree with Bazilnerk! It will take time, but it's already being refined at an exponential rate. It might be far-out to disassemble Beatles music. But, it's scary to know that machines will be able to sort the din of a crowded room into individual conversations, identify the individuals involved and then plot their locations against recent movement and finally enter the pending concerns that might be urgent or incomplete(warrants, unpaid debt, AWOL, etc). Oh, look!!! Here comes the handcuff-bot! And, ALL of the bots are named HAL, Johnny Cab, Or Judas.

Okay, that's kind of different to what i was thinking. I was thinking more of guiding an AI demixer by giving it the melody of the harmony, so it can decide which vocal is which. SL is a manual spectral demixer isn't it, so is 'dumb" in the sense that it doesn't know what anything is unless you tell it.

Come on, there must be some hackers reading this. Here's your chance to make your name.

No, it was just that I don't think I've ever in my life expected anyone to "respect" me. When I was a kid it was only old people who talked about respect, and now that I'm old it's only teenagers who talk about it. Go figure! :?

Annotated source separation is a thing but recent research has focused on blind separation.
