Question about modulation of frequency band crossovers – MeldaProduction Forum

I’ve recently gotten MRhythmizerMB and MHarmonizerMB, and there is one thing I can not figure out:
some of the presets and devices of these, when examined in the band editor, show the crossovers of the bands to be modulating. But nowhere can find any controls related to this modulation, nor have I come across any documentation acknowledging it. Surely I am missing something, but I can’t figure out what it is. Any help would be appreciated.
