Hello audio lovers...
I'd like to ask if anyone knows exactly what types of software, tools and voices various AI sites use to create their songs.

We've got a bet going among friends: Some maintain they exclusively use GM instruments (like Xpand or similar Roland/Yamaha) and voices trained with software like Replay and similar.
Others, however, say no, meaning they use most advanced instruments like Kontakt and specific plugs AU-VSTs/Synthesizer V.
Does anyone know something more precise and confirmed about this? Perhaps there's an official page where one could learn?

I’m waiting for your opinions to win the bet...

AI don't create songs like humans do. They don't use virtual instruments.
Engines take real songs, analyse them and "concatenate" audio elements on demand.

Here is a beginning :

Of course, it may sound like GM or Kontakt instruments, because real songs use GM, Kontakt ...
But AI don't generate MIDI notes to feed a virtual instrument.

 

Soundful has a sound engine as far as i know, with their own synths and sound library. Its more of an algorithmic generator, they use machine learning models to generate midi then use that to generate a song. There might be using direct ai models for some of the options like the vocal chops generator.
