How do I get the LFO to reset on each note?

First, make sure that you have modulation assigned to something (Ex. Pitch, Filter, etc..).

Patch from the KB GATE output in the ARP/SEQ module, to the SYNC input in the MODULATION module. Now, each time a note is played, the cycle of the modulation LFO will be reset with each new note. Slower LFO speeds can act similarly to a second envelope, while faster LFO speeds can impart swing, act as a flam / ratchet, or even be used to mimic delay effects.
