Up to eight pitch shifted voices are created from vocal input or instruments. Separate algorithms for optimal shifting of vocals/monophonic instruments and for any other kind of audio.

Position each voice in space ( left and right / front and back )

Modify the voice character from male to female and vice versa.

Pitch shift each voice in the range of +/- one octave with preserving of formants for natural sound.

Applying separate feedback delays on each voice creates complex rhythmical patterns.

Seems good however

I played with this app briefly but the AU and IAP are not working... I'm sure they will fix this soon. I was able to use Audiobus 2 with it, but I don't really use audiobus and it's supposed to have AU and IAP. I'm using iPad Air 2 and iPhone 6 on iOS 10.3.2 both have same problem. Tried both AU and IAP in Cubasis, GarageBand, and Modstep.

Great for harmonizing single voices and treble instruments

That's all I've tried so far, but it worked great with these. It's best to use this app on clean, sounds pre any effects processing, I've found.
