Envelope filter kind of auto wah sound into triplet delay. Expression pedal adds feedback, holding current preset footswitch slows down delay to half time.

Disclaimer:
Most of my patches are made from scratch (some started from factory presets). Most require firmware 1.1 (or possibly 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 an experiment with pedal positions :-)
