Currently, one of the best instrumental results (if not the best). Not so good vocals.
(for older models) The combination of 3 different aggression settings (mostly the most aggressive in busy mix parts) gives the best results for Childish Gambino - Algorithm vs our top ensemble settings so far. But it's still far from ideal (and [not only] the most aggressive one makes instruments very muffled [but vocals are better cancelled too], although our separation makes it even a bit worse in more busy mix fragment).
As for drums - better than GSEP, worse than Demucs 4 ft 32, although a bit better hihat. Not too easy track and already shows some diffrences between just GSEP and Demucs when the latter has more muffled hi-hats, but better snare, and it rather happens a lot of times
(old) Samples:
Also, it automatically picks the first fragment for preview when vocal appears, so it is difficult to write something like AS Tool for that (probably manipulations by manual mixing of fake vocals would be needed). Actually, smudge wrote one.
Very promising results even for earlier version.
They wrote once somewhere about limited previews for stem mode (for more than 2 mode) and free credits, but haven’t encountered it yet.
They’re accused by aufr33 to use some of UVR models for 2 stems in the past, without crediting the source (and taking money for that).
Now new, better models are released. Better instrumentals than in UVR/MVSep, and not the same models.
It used to be possible to get free 30 seconds samples on dango.ai, but recently 5 samples are available for free (?also) here:
