more crappy cover bands can perfect their mediocrity

@Vitaliy Actually it is kinda of like magic. And it's not a level playing field. Rare the individual with perfect pitch capability, and if you're not born with it, or if you're not trained as a child from a "master", it likely won't ever be learned. The process of figuring out a song is fundamental to developing whatever talent a person is born with. But for the package loop guys, this might be their ticket, like paint-by-numbers painters, or free chord progressions for garageband....or autogenerating video makers. Sadly the democratization of music has only produced progressively worse music, like all digital revolutions. False prophets. Maybe that's their motive. There's some interesting political theories on the disappearance of melody in contemporary music. Three-note melodies dominate our brains, like subtle voice-of-god weapons.

Obviously you don't know how rare it is for an adult to learned perfect pitch. Perhaps you're thinking of relative pitch ? And mozart ? Symphonies at 6 ? Great musicians often exhibit their skill predisposition before 2 years old, many times to parents that aren't musically inclined. Let me see....taylor swift ...or annie lennox. That's a tough one ! And I have no idea what's your meaning of "filtering" ? What I know about this program is that musicians that exclusively use it , will never develop necessary skills. Perhaps just to check if they were right , or not ? And what I know about contemporary western music is...it's gone way downhill since I was a kid. And so it goes....with photography and film as well. I do appreciate my polyphonic clip-on tuner however.

Perfect pitch is what this program does. And it probably outperforms most humans. Computers can beat us at chess too. Does that mean we don't learn to play with people ? I agree, the problem is with the system, but that type of filtering always existed. But now the system is being manipulated for other motives rather than profit off talent, imho. The rulers (the system) are dumbing humans down on purpose. In america, white kids from suburbia are speaking like they grew up rapping in east baltimore. How many Avenger movies does a person have to endure ? ps...I shoulda said "child prodigies" show their skills before the age of 2...not "great musicians". Obviously musicmanship can be learned, and can be vastly improved with hard work, at any age. And even prodigies are created by their nourishing environment.

Well, actually, perfect pitch and perfect relative pitch, and absolute pitch have some serious professional advantages.
Just as one example, suppose someone says something to you, and you write it down. Suppose someone says something, and you can't, in fact write it down. That's a type of literacy. But that's also a musical skill. You hear a song, you write it down. At the conservatory, we are required to hear a four part Bach chorale and write it down. At a minimum.
These abilities affect all aspects of music, including improv--you hear a riff, you know what the notes are, you riff on the riff. If you are exposed to music at an early age, you develop some extra brain layers. If you aren't, you don't. Same thing with languages--if you wait too long, you can learn them but it isn't the same. Lack of exposure to music (which the situation now as programs are simply removed for huge parts of the country) puts you at a huge disadvantage if you choose music as your career, but almost all disadvantages can be overcome by extra hard work and extra training. At the top level, that extra 1 or 2 percent of ability makes the difference in who gets a job, since the competition is so steep.
Who knows where all this is going? It used to be that pop musicians were in fact very highly trained. That might change for a significant percentage of the industry. As far as Classical, I think it will probably stay conservative for a while....and all the fake stuff will be used in videos as it already is on albums.
