What John is describing uses the Elastique algorithm, introduced several years ago to BIAB. It allows pitch shifting without artifacts if the shift is only a step or two.

What Trevor is describing, inversions, cannot be directly controlled in BIAB. The best you can do is continue to regenerate until you hear an inversion you like. RealBand can do this on specific phrases.
