Polyphonic one-octave-down pitch shifting like on an EHX POG. Unfortunately, tracking is much slower on an LVX than on a POG, and you can only have either octave up or octave down, while all pedals of the POG family can do both simulataneously.

Disclaimer:
Most of my patches are made from scratch (some started from factory presets). Most require firmware 1.1 (or higher). Most were programmed with an expression pedal hooked up to the LVX. So, if the preset does nothing or way too much, you may have to connect an expression pedal and experiment with pedal positions :-)
