0013         <comment>Amount of gain in delayed signal into right and vice versa.
0014 Gives a delay effect of left signal in right output and vice versa which gives widening effect.</comment>

0018         <comment>Cross feed of left into right with inverted phase. This helps in suppressing the mono.
0019 If the value is 1 it will cancel all the signal common to both channels. </comment>
