Feedback means returning the effect sound back into the
input. The feedback level specifies the amount of sound
that is returned. Cross-feedback is when the effect sound is
returned back to the opposite-side (left or right) input. The
cross-feedback level specifies the amount of sound that is
returned. In modulation-type effects, raising the feedback
value will make the sound richer and more spacious.
Negative values will invert the phase.
