LFO sync
When turned from off to on it resets the phase of the LFO back to the start of the cycle. Used to sync the LFO to the track.
LFO period (s)
The cycle period of the LFO in seconds.
LFO depth (ms)
The maximum delay the LFO will use to flange, in milliseconds.
Feedback (%)
The amount of the delays output that is mixed back into the delay.
