I still haven’t had a chance to look into it. Sound demos were definitely underwhelming. It’s kinda doing what the harmann neuron synth was doing back in the early 2000s, but worse. Or maybe the same. You probably haven’t heard of the harmann neuron for a reason.
And the Izotope stuff is alright for pop and rock probably, but not super well tuned for dnb or idm or house. All it knows is “this is a synthesizer and in a normal mix it would sound good to do this” so it does it. Then you toss another synthesizer at it and it does the same thing. It can’t fathom that one of these is a lead, one is a bass layer, then there’s another bass layer and a separate lead effects bus and so on. But the AI is mostly in the ability to identify different instruments, which it then takes to a lookup table of settings. Kinda like how Excel does calculus (it doesn’t, just looks up common statistics solutions without actually integrating the area under the probability curve).
